Response to Arguments
Response to Arguments
Applicant’s Amendments and Arguments filed 03/10/2026 have been considered for examination. Claims 62-81 are pending in the instant application.
With regard to the 103 rejections, Applicant’s arguments filed 03/10/2026 (see pages 8-9 of Remarks) in view of the amendments have been fully considered but are not persuasive at least in view of the reasons set forth below. Therefore, the 103 rejections of the previous office action will be maintained in the instant office action.
Regarding claims 62, Applicant argued:
In the argument, regarding the claim 62, recited as “a set of flags … wherein the set of flags includes a separate flag for each feature of said more than one feature,” Ishii does not teach or suggest the use of a set of flags where each flag represents a distinct feature that can be combined into a signaled "set."
The Patent Office conflates "indices" with "flags." An index is a value used to select one specific state or entry from a pre-defined list. In contrast, the claimed "set of flags" requires a structure where individual indicators (flags) correspond to specific features. For instance, as noted in Section 1-1 of Ishii, the table includes a highSpeedFlag, which is a singular binary indicator. However, the other elements are indices or parameters used to select a UE category (e.g., NB-IoT vs. Normal UE). One singular flag is not a "set of flags" where a "separate flag" exists for each feature. As illustrated above, an index selects a single row, whereas a set of flags (like a bitmask) allows for the simultaneous indication of multiple different features. Ishii lacks the teaching of a single PRACH resource selection that is governed by a set of mapping flags to indicate a combination of multiple different features.
Further, based on Paragraphs [1086] and [0679], Ishii teaches using different preambles to distinguish features, rather than using the mapping information itself (via a set of flags) to define which features are associated with a specific resource.
Therefore, claim 62 is allowable over the combination of Cozzo and Ishii.
In response to Applicant’s argument, Examiner respectfully disagrees.
In the argument, Applicant argued regarding the part of the claim 62, recited as ““a set of flags … wherein the set of flags includes a separate flag for each feature of said more than one feature,” combination of Cozzo and Ishii fail to disclose. However, Examiner respectfully disagrees.
Applicant argues that the patent office conflates “indices” with “flags”. However, Examiner respectfully disagrees.
First of all, in the claim, regarding “set of flags”, the limitation is that the set of flag indicates a set of features mapped to the PRACH resource and that the set of flags includes a separate flag for each feature. Based on this limitation, the indices, parameters, config set or Information Element (IE) can be “set of flags”, since they can have this functionality or the structure for the set of flags in the claim. For example, in the table of Ishii shown in Page 7-9, PRACH-Configinfo contains the indicators such as Configlndex, highSpeedFlag, zeroCorrelationZoneConfig, and prach-FreqOffset and each indicator represent its feature and is mapped to PRACH resources. Thus, PRACH-Configinfo can be “set of flags” defined in the claim and each indicator can be “flag” defined in the claim. Further, in Section 1-1 to 1-4 of Ishii, various examples can be found. Thus, Ishii clearly disclose this matter.
Further, regarding the second matter, recited in the argument as “Ishii teaches using different preambles to distinguish features, … to define which features are associated with a specific resource,” based on Paragraphs [1086] and [0679] of Ishii. However, Examiner respectfully disagrees.
As Applicant said in the agreement, In Paragraph [0679], Ishii teach that Fig. 12B approach use two preambles to distinguish features for two different time periods, respectively. However, for each period, only one preamble is transmitted using the selected PRACH resource for indicating the set of features with some indicators. It still satisfies with the claim 62, since in the claim, there is no limitation about the number of preambles and the number of periods or time durations. Namely, in the one time period, the approach of Fig. 12B is corresponding to the approach of the claim, such that “the PRACH preamble is transmitted using the selected PRACH resource for indicating the set of features to the network node,” as recited in the claim. Thus, the approach inf Fig. 12B shows that in the different time periods, for the different feature, the different preamble can be applied for the efficiency. Therefore, the Applicant’s approach can be considered as the single preamble transmission using PRACH resources with indicators of set of features, while as shown in Fig. 12A, Ishii, to extend the Applicant’s approach when the wireless device receives multiple requests from the network node, but the PRACH resources regarding some request are not available, transmits different preambles using different PRACH resources in the different time period, sequentially, when the PRACH resources per the request are available. Thus, Ishii’s approach in Paragraph [0679] can be considered as a kind of extension of Applicant’s approach for the special case, since when considering one time period, Ishii’s approach discloses the approach of the claim. Thus, clearly Ishii discloses the claim 62.
By the above reasoning, the claim 62 is clearly disclosed by combination of Cozzo and Ishii and, in similar, the claims 72 and 81 is clearly disclosed by combination of Cozzo and Ishii.
Therefore, the 103 rejections in the previous office action are maintained in the instant office action in the below.

Claims 62-70, 72-76, and 78-81 are rejected under U.S.C. 103 as being unpatentable Cozzo, Carmela and et. al. (Int. Pub. No.: WO 2022186614 A1, hereinafter “Cozzo”) in a view of Atsushi Ishii (USPub No.: US 20180317263 A1, hereinafter “Ishii”)
Regarding claim 62, Cozzo teaches that a method performed by a wireless communication device, the method comprising: receiving, from a network node, information that indicates mappings between a plurality of Physical Random Access Channel, PRACH, resources and a plurality of sets of features; (Cozzo, in Fig. 11 and in Paragraphs [128]-[130], teaches that in step 1110, a UE (such as the UE 116: a wireless device) is provided a configuration for first and second TDRA (Time Domain Resource Allocation) tables, wherein the first table (the first mapping table) is associated to a Msg3 PUSCH (Physical Uplink Shared Channel) transmission with repetitions (the first feature) and the second table (the second mapping table) is associated to a Msg3 PUSCH transmission with no repetitions (the second feature). In step 1120, the UE is provided a configuration for a first and second PRACH resources partitions. Here a first partition is associated to the first TDRA table and a second partition is associated to the second partition, and an RSRP threshold. The partition can be based on (i) PRACH preambles or (ii) PRACH preambles and ROs(RACH Occasions). In certain embodiments, the RSRP threshold that the UE uses to select a PRACH resources or preambles partition is associated to a Msg3 PUSCH transmission (step 1120). Here the Msg3 transmission can be with or without repetitions. The threshold can be same as the threshold rsrp (reference signal received power)-ThresholdSSB (Synchronization Signal Block) configured in RACH-ConfigCommon IE that the UE may use to select the SS (Synchronization Signal) block. In step 1130, the UE selects a TDRA table based on RSRP measurements and the configured threshold. Therefore, it is clear that a wireless communication device (an UE) may perform to receive, from a network node (a base station), information that indicates mappings between a plurality of Physical Random Access Channel, PRACH resources and a plurality of sets of features.) selecting a PRACH resource from among the plurality of PRACH resources, the received information indicating a mapping between the selected PRACH resource and a set of features of the plurality of sets of features; (Cozzo, in Fig. 11 and in Paragraphs [128]-[130], teaches that in step 1110, a UE (such as the UE 116: a wireless device) is provided a configuration for first and second TDRA (Time Domain Resource Allocation) tables, wherein the first table (the first mapping table) is associated to a Msg3 PUSCH (Physical Uplink Shared Channel) transmission with repetitions (the first feature) and the second table (the second mapping table) is associated to a Msg3 PUSCH transmission with no repetitions (the second feature). In step 1120, the UE is provided a configuration for a first and second PRACH resources partitions. Here a first partition is associated to the first TDRA table and a second partition is associated to the second partition, and an RSRP threshold. The partition can be based on (i) PRACH preambles or (ii) PRACH preambles and ROs (RACH Occasions). In certain embodiments, the RSRP threshold that the UE uses to select a PRACH resources or preambles partition is associated to a Msg3 PUSCH transmission (step 1120). Here the Msg3 transmission can be with or without repetitions. The threshold can be same as the threshold rsrp (reference signal received power)-ThresholdSSB (Synchronization Signal Block) configured in RACH-ConfigCommon IE that the UE may use to select the SS (Synchronization Signal) block. In step 1130, the UE selects a TDRA table based on RSRP measurements and the configured threshold. Therefore, it is clear that a PRACH resource from among the plurality of PRACH resources is selected based on the received information indicating a mapping between the selected PRACH resource and a set of features of the plurality of sets of features.) and transmitting a PRACH preamble using the selected PRACH resource, for indicating the set of features to the network node, (Cozzo, in Paragraphs [125]-[126], teaches that a gNB (such as the BS 102) can configure more than one TDRA (Time Domain Resource Assignment) table that a UE (such as the UE 116) can use to determine a resource allocation for a Msg3 PUSCH transmission, and configure partitions of PRACH resources associated to the TDRA tables. One table can be associated to Msg3 transmission without repetitions and one or more tables can be associated to Msg3 transmission with repetitions, or all tables can be associated to Msg3 with repetitions. A UE can select one of the configured TDRA tables and transmit a PRACH preamble in a RACH occasion (RO) or in a set of ROs selected from the PRACH resources associated to the selected TDRA table. The RO or the set of ROs can be used by any of the preambles of the different partitions. After reception of the PRACH preamble, the gNB can schedule a Msg3 transmission in an allocated resource, wherein resource allocation is done using the selected TDRA table. The UE then transmits a Msg3 PUSCH according to the indication of a PUSCH time resource allocation field in RAR from the selected table. A gNB (such as the UE 116) can also configure in a SIB one or more reference signal received power (RSRP) thresholds that a UE can use to select a TDRA table from the TDRA tables configured in the SIB. Therefore, it is clear that a PRACH preamble is transmitted by using the selected PRACH resource, for indicating the set of features to the network node.)
However, Cozzo does not explicitly teach that wherein the information that indicates the mappings between the plurality of PRACH resources and the plurality of sets of features comprises, for a PRACH resource of the plurality of PRACH resources, a set of flags that indicates a set of features mapped to the PRACH resource, wherein the set of features mapped to the PRACH resource comprises more than one feature; and wherein the set of flags includes a separate flag for each feature of said more than one feature.
Ishii teaches that wherein the information that indicates the mappings between the plurality of PRACH resources and the plurality of sets of features comprises, for a PRACH resource of the plurality of PRACH resources, a set of flags that indicates a set of features mapped to the PRACH resource, wherein the set of features mapped to the PRACH resource comprises more than one feature; and wherein the set of flags includes a separate flag for each feature of said more than one feature (Ishii, in section 1-1, 1-2, and 1-3, in Paragraphs [0051]-[0053], in Paragraphs [0071]-[0110], in Paragraphs [0131]-[0164], and in Paragraphs [0165]-[0176] teaches that in section 1-1 and in Paragraph [0051], UE receives necessary configuration information broadcasted as System Information from a current serving cell. The table in the section 1-1 show the PRACH resources and corresponding indicators (indices or flags) for multiple features and in Paragraphs [0071]-[0110], they are explained, respectively. In Paragraphs [0131]-[0164] in the section 1-2, based on the table, the selection of PRACH resource for PRACH preamble transmission is performed and the procedure of the selection is described in Paragraphs [0131]-[0164]. In this procedure, multiple resources and indices (flags) selected and their mapping are described based on the UE characteristics such as NB-IoT UE, BL (Bandwidth reduced Low Complexity) UE, or Normal UE (general UE). In the section 1-3 and in Paragraphs [0165]-[0176], by applying the selected resources, parameters and corresponding indices for multiple features, the procedure of PRACH preamble transmission performed by UE is described. According to this observation, multiple resources or parameters and corresponding indices (flags or indicators) for multiple features are selected for PRACH preamble transmission, based on the table in the broadcasted RRC System Information messages and applied for PRACH preamble transmission. Therefore, it is clear that the information that indicates the mappings between the plurality of PRACH resources and the plurality of sets of features comprises a set of flags that indicates a set of features mapped to the PRACH resource, where the set of features mapped to the PRACH resource comprises more than one feature and the set of flags includes a separate flag for each feature of said more than one feature.
It would have been obvious for one of ordinary skill in the art, before the effective filing date of the claimed invention, to combine Cozzo and Ishii to include the technique of wherein the information that indicates the mappings between the plurality of PRACH resources and the plurality of sets of features comprises, for a PRACH resource of the plurality of PRACH resources, a set of flags that indicates a set of features mapped to the PRACH resource, wherein the set of features mapped to the PRACH resource comprises more than one feature; and wherein the set of flags includes a separate flag for each feature of said more than one feature of Ishii in the system of Cozzo to provide methods and apparatus for performing a random access procedure (RACH) in wireless communications, providing a set of PRACH preambles to be reserved for upper layer to inform the network of a designated request/notification using the RACH process without performing a subsequent data transfer (Ishii, see Paragraphs [0002] and [0008]).).
Regarding claim 63, combination of Cozzo and Ishii teaches the features defined in the claims 62, -refer to the indicated claim for reference(s).
Cozzo further teaches that wherein each PRACH resource of the plurality of PRACH resources is mapped to a different one of the plurality of sets of features (Cozzo, in Fig. 11 and in Paragraphs [128]-[130], teaches that in step 1110, a UE (such as the UE 116: a wireless device) is provided a configuration for first and second TDRA (Time Domain Resource Allocation) tables, wherein the first table (the first mapping table) is associated to a Msg3 PUSCH transmission with repetitions (the first feature) and the second table (the second mapping table) is associated to a Msg3 PUSCH transmission with no repetitions (the second feature). In step 1120, the UE is provided a configuration for a first and second PRACH resources partitions. Here a first partition is associated to the first TDRA table and a second partition is associated to the second partition, and an RSRP threshold. The partition can be based on (i) PRACH preambles or (ii) PRACH preambles and ROs (RACH Occasions). In certain embodiments, the RSRP threshold that the UE uses to select a PRACH resources or preambles partition is associated to a Msg3 PUSCH transmission (step 1120). Here the Msg3 transmission can be with or without repetitions. The threshold can be same as the threshold rsrp-ThresholdSSB configured in RACH-ConfigCommon IE that the UE may use to select the SS block. In step 1130, the UE selects a TDRA table based on RSRP measurements and the configured threshold. Therefore, it is clear that each PRACH resource of the plurality of PRACH resources is mapped to a different one of the plurality of sets of features.)
Regarding claim 64, combination of Cozzo and Ishii teaches the features defined in the claims 62, -refer to the indicated claim for reference(s).
Cozzo further teaches that wherein at least one of the plurality of sets of features is mapped to more than one of the plurality of PRACH resources (Cozzo, in Paragraph [135], teaches that when a partition of PRACH resources is associated to a UE type (for example, a PRACH resources or preambles partition A is for RedCap (Reduced Capability) UEs and a PRACH resources or preambles partition B is for non-RedCap UEs, or to a UE capability, for example, a PRACH resource partition A is for UEs supporting a coverage enhancement (CE) feature or a group of CE features and a PRACH resource partition B is for UEs not supporting the CE feature or the group of CE features of partition A), for PRACH retransmission after the initial PRACH transmission, the UE uses the same PRACH resource or a different resource from the same partition. A PRACH resource can comprise one or more PRACH preambles associated to one or more ROs (RACH Occasions), wherein the mapping between PRACH preambles and ROs can be a l-to-1 or a 1-to-N mapping. Alternatively, initial PRACH transmission and PRACH retransmission can be resources from different partitions. In this observation, it is clear that one feature set may be mapped more than one of the pluralities of PRACH resources.).
Regarding claim 65, combination of Cozzo and Ishii teaches the features defined in the claims 62, -refer to the indicated claim for reference(s).
Cozzo further teaches that wherein two or more of the plurality of PRACH resources, but not all of the plurality of PRACH resources, are mapped to a same set of features (Cozzo, in Paragraph [135], teaches that initial PRACH transmission and PRACH retransmission can be resources from different partitions. For example, when a UE is provided a configuration for a first and second PRACH resources or preambles partitions, wherein the first PRACH resources or preambles partition is associated to non-CE features and the second PRACH resource partition is associated to CE features, if the initial transmission with a PRACH resource from the first partition fails, the UE can use a PRACH resource from the second partition for retransmission. Whether initial PRACH transmission and PRACH retransmission use same or different PRACH resources from different PRACH resources or preambles partitions can be configured in SIB. Therefore, it is clear that two or more of the plurality of PRACH resources, but not all of the plurality of PRACH resources, are mapped to a same set of features.).
Regarding claim 66, combination of Cozzo and Ishii teaches the features defined in the claims 62, -refer to the indicated claim for reference(s).
Cozzo further teaches that wherein a PRACH resource is a random access channel occasion (RO) (Cozzo, in Paragraphs [125]-[126], teaches that a gNB (such as the BS 102) can configure more than one TDRA (Time Domain Resource Assignment) table that a UE (such as the UE 116) can use to determine a resource allocation for a Msg3 PUSCH transmission, and configure partitions of PRACH resources associated to the TDRA tables. One table can be associated to Msg3 transmission without repetitions and one or more tables can be associated to Msg3 transmission with repetitions, or all tables can be associated to Msg3 with repetitions. A UE can select one of the configured TDRA tables and transmit a PRACH preamble in a RACH occasion (RO) or in a set of ROs selected from the PRACH resources associated to the selected TDRA table. The RO or the set of ROs can be used by any of the preambles of the different partitions. After reception of the PRACH preamble, the gNB can schedule a Msg3 transmission in an allocated resource, wherein resource allocation is done using the selected TDRA table. The UE then transmits a Msg3 PUSCH according to the indication of a PUSCH time resource allocation field in RAR from the selected table. A gNB (such as the UE 116) can also configure in a SIB one or more reference signal received power (RSRP) thresholds that a UE can use to select a TDRA table from the TDRA tables configured in the SIB. Therefore, it is clear that a PRACH preamble is transmitted by using the selected PRACH resource, for indicating the set of features to the network node. Therefore, it is clear that a PRACH resource is a random access channel occasion (RO).).
Regarding claim 67, combination of Cozzo and Ishii teaches the features defined in the claims 62, -refer to the indicated claim for reference(s).
Cozzo further teaches that wherein the information that indicates the mappings between the plurality of PRACH resources and the plurality of sets of features comprises, for a PRACH configuration, information that indicates a mapping of a first subset of PRACH resources of the PRACH configuration to a first set of features and information that indicates a mapping of a second subset of the PRACH resources of the PRACH configuration to a second set of features (Cozzo, in Paragraph [133], teaches that in the above, we have learned UE receives the information that indicates the mappings between the plurality of PRACH resources and the plurality of sets of features for a PRACH configuration. When a UE is provided a configuration for first and second PRACH resources or preambles partitions, the UE can determine whether to select a PRACH resource from the first PRACH resources or preambles partition or from the second PRACH resources or preambles partition based on an RSRP measurement. In this example, the first PRACH resources or preambles partition can be associated to a first TDRA (Time Domain Resource Assignment) table and the second PRACH resources or preambles partition can be associated to a second TDRA table. For a second example, the first PRACH resources or preambles partition can be associated to a Msg3 PUSCH transmission with repetitions and the second PRACH resources or preambles partition can be associated to a Msg3 PUSCH transmission without repetitions. In this observation, it is clear that the information that indicates the mappings between the plurality of PRACH resources and the plurality of sets of features comprises, for a PRACH configuration, information that indicates a mapping of a first subset of PRACH resources of the PRACH configuration to a first set of features and information that indicates a mapping of a second subset of the PRACH resources of the PRACH configuration to a second set of features.).
Regarding claim 68, combination of Cozzo and Ishii teaches the features defined in the claims 67, -refer to the indicated claim for reference(s).
Cozzo further teaches that wherein the different subsets of the plurality of PRACH resources comprise different sets of preambles within a PRACH resource (Cozzo, in Paragraph [125], teaches that a gNB (such as the BS (base station) 102) can configure more than one TDRA (Time Domain Resource Assignment) table that a UE (such as the UE 116) can use to determine a resource allocation for a Msg3 PUSCH transmission, and configure partitions of PRACH resources associated to the TDRA tables. One table can be associated to Msg3 transmission without repetitions and one or more tables can be associated to Msg3 transmission with repetitions, or all tables can be associated to Msg3 with repetitions. A UE can select one of the configured TDRA tables and transmit a PRACH preamble in a RACH occasion (RO) or in a set of ROs selected from the PRACH resources associated to the selected TDRA table. The RO or the set of ROs can be used by any of the preambles of the different partitions. Namely, the different TDRA table indicates different subset of the feature and the preambles of the different partitions. Therefore, it is clear that the different subsets of the plurality of PRACH resources comprise different sets of preambles within a PRACH resource.).
Regarding claim 69, combination of Cozzo and Ishii teaches the features defined in the claims 62, -refer to the indicated claim for reference(s).
Cozzo further teaches that wherein the information that indicates the mappings between the plurality of PRACH resources and the plurality of sets of features comprises, for a PRACH resource from among the plurality of PRACH resources, information that indicates a mapping of a first set of PRACH preambles for the PRACH resource to a first set of features and information that indicates a mapping of a second set of the PRACH preamble for the PRACH resource to a second set of features (Cozzo, in Fig. 11 and in Paragraphs [127]-[129], teaches that in the above, we have learned UE receives the information that indicates the mappings between the plurality of PRACH resources and the plurality of sets of features. Further, Fig. 11 describes an example procedure for a UE to determine a resource allocation in time domain for Msg3 PUSCH transmission by selecting a TDRA table from the configured TDRA tables in SIB (System Information Block). In step 1110, a UE (such as the UE 116) is provided a configuration for first and second TDRA tables, wherein the first table is associated to a Msg3 PUSCH transmission with repetitions and the second table is associated to a Msg3 PUSCH transmission with no repetitions. A TDRA table can be configured based on the corresponding feature by a base station. In step 1120, the UE is provided a configuration for a first and second PRACH resources partitions based on TDRA tables. A first partition is associated to the first TDRA table and a second partition is associated to the second TDRA table, and an RSRP threshold. The partition can be based on (i) PRACH preambles or (ii) PRACH preambles and ROs (RACH Occasions). In certain embodiments, the RSRP threshold that the UE uses to select a PRACH resources or preambles partition is associated to a Msg3 PUSCH transmission (step 1120). The Msg3 transmission can be with or without repetitions. The threshold can be same as the threshold rsrp-ThresholdSSB configured in RACH-ConfigCommon IE that the UE may use to select the SS (Synchronization Signal) block. Based on this observation, it is clear that the information that indicates the mappings between the plurality of PRACH resources and the plurality of sets of features may comprise information that indicates a mapping of a first set of PRACH preambles for the PRACH resource to a first set of features (the first TDRA table) and information that indicates a mapping of a second set of the PRACH preamble for the PRACH resource to a second set of features (the 2nd TDRA table).).
Regarding claim 70, combination of Cozzo and Ishii teaches the features defined in the claims 62, -refer to the indicated claim for reference(s).
Cozzo further teaches that wherein the plurality of PRACH resources from a plurality of random access occasions (RO), the plurality of ROs being a common pool of ROs dedicated for feature signaling; (Cozzo, in Paragraphs [125], teaches that a gNB (such as the BS 102) can configure more than one TDRA (Time Domain Resource Assignment) table that a UE (such as the UE 116) can use to determine a resource allocation for a Msg3 PUSCH transmission, and configure partitions of PRACH resources associated to the TDRA tables. One table can be associated to Msg3 transmission without repetitions and one or more tables can be associated to Msg3 transmission with repetitions, or all tables can be associated to Msg3 with repetitions. A UE can select one of the configured TDRA tables and transmit a PRACH preamble in a RACH occasion (RO) or in a set of ROs selected from the PRACH resources associated to the selected TDRA table. The RO or the set of ROs can be used by any of the preambles of the different partitions. Therefore, it is clear that the plurality of PRACH resources may be selected from a plurality of PRACH occasions in a common pool of PRACH occasions dedicated for feature signaling.) and the information that indicates the mappings between the plurality of PRACH resources and the plurality of sets of features comprises, for each of a plurality of features, a feature configuration that comprises information that indicates one or more ROs from the common pool of ROs dedicated for feature signaling that are mapped to the feature (Cozzo, in Paragraphs [125]-[126], teaches that in the above, we have learned a UE receives the information that indicates the mappings between the plurality of PRACH resources and the plurality of sets of features. Further, a gNB (such as the BS 102) can configure more than one TDRA (Time Domain Resource Assignment) table that a UE (such as the UE 116) can use to determine a resource allocation for a Msg3 PUSCH transmission, and configure partitions of PRACH resources associated to the TDRA tables. One table can be associated to Msg3 transmission without repetitions and one or more tables can be associated to Msg3 transmission with repetitions, or all tables can be associated to Msg3 with repetitions. A UE can select one of the configured TDRA tables and transmit a PRACH preamble in a RACH occasion (RO) or in a set of ROs selected from the PRACH resources associated to the selected TDRA table. The RO or the set of ROs can be used by any of the preambles of the different partitions. After reception of the PRACH preamble, the gNB can schedule a Msg3 transmission in an allocated resource, wherein resource allocation is done using the selected TDRA table. The UE then transmits a Msg3 PUSCH according to the indication of a PUSCH time resource allocation field in RAR from the selected table. A gNB (such as the UE 116) can also configure in a SIB one or more reference signal received power (RSRP) thresholds that a UE can use to select a TDRA table from the TDRA tables configured in the SIB. Therefore, it is clear that the information that indicates the mappings between the plurality of PRACH resources and the plurality of sets of features is received and for each of a plurality of features, a feature configuration may comprise information that indicates one or more PRACH occasions from the common pool of PRACH occasions dedicated for feature signaling that are mapped to the feature.).
Regarding claim 72, Cozzo teaches that a wireless communication device comprising: one or more transmitters; one or more receivers; and processing circuitry associated with the one or more transmitters and the one or more receivers, the processing circuitry configured to cause the wireless communication device to: (Cozzo, in Fig. 3 and in Paragraphs [68]-[70], teaches that as shown in Fig. 3, the UE 116 includes an antenna 305, a RF transceiver 310, TX processing circuitry 315, a microphone 320, and receive (RX) processing circuitry 325. The UE 116 also includes a speaker 330, a processor 340, an input/output (1/0) interface (IF) 345, an input device 350, a display 355, and a memory 360. The memory 360 includes an operating system (OS) 361 and one or more applications 362. The RF transceiver 310 receives, from the antenna 305, an incoming RF signal transmitted by a BS of the wireless network 100. The RF transceiver 310 downconverts the incoming RF signal to generate an intermediate frequency (IF) or baseband signal. The IF or baseband signal is sent to the RX processing circuitry 325 that generates a processed baseband signal by filtering, decoding, and/or digitizing the baseband or IF signal. The TX processing circuitry 315 receives outgoing baseband data from the processor 340. The TX processing circuitry 315 encodes, multiplexes, and/or digitizes the outgoing baseband data to generate a processed baseband or IF signal. Therefore, it is clear that a wireless communication device comprising one or more transmitters, one or more receivers, and processing circuitry associated with the one or more transmitters and the one or more receivers and the processing circuitry is configured to perform the wireless communication device.) receive, from a network node, information that indicates mappings between a plurality of Physical Random Access Channel, PRACH, resources and a plurality of sets of features; (Cozzo, in Fig. 11 and in Paragraphs [128]-[130], teaches that in step 1110, a UE (such as the UE 116: a wireless device) is provided a configuration for first and second TDRA (Time Domain Resource Allocation) tables, wherein the first table (the first mapping table) is associated to a Msg3 PUSCH (Physical Uplink Shared Channel) transmission with repetitions (the first feature) and the second table (the second mapping table) is associated to a Msg3 PUSCH transmission with no repetitions (the second feature). In step 1120, the UE is provided a configuration for a first and second PRACH resources partitions. Here a first partition is associated to the first TDRA table and a second partition is associated to the second partition, and an RSRP threshold. The partition can be based on (i) PRACH preambles or (ii) PRACH preambles and ROs(RACH Occasions). In certain embodiments, the RSRP threshold that the UE uses to select a PRACH resources or preambles partition is associated to a Msg3 PUSCH transmission (step 1120). Here the Msg3 transmission can be with or without repetitions. The threshold can be same as the threshold rsrp (reference signal received power)-ThresholdSSB (Synchronization Signal Block) configured in RACH-ConfigCommon IE that the UE may use to select the SS (Synchronization Signal) block. In step 1130, the UE selects a TDRA table based on RSRP measurements and the configured threshold. Therefore, it is clear that a wireless communication device (an UE) may perform to receive, from a network node (a base station), information that indicates mappings between a plurality of Physical Random Access Channel, PRACH resources and a plurality of sets of features.) select a PRACH resource from among the plurality of PRACH resources, the received information indicating a mapping between the selected PRACH resource and a set of features of the plurality of sets of features; (Cozzo, in Fig. 11 and in Paragraphs [128]-[130], teaches that in step 1110, a UE (such as the UE 116: a wireless device) is provided a configuration for first and second TDRA (Time Domain Resource Allocation) tables, wherein the first table (the first mapping table) is associated to a Msg3 PUSCH (Physical Uplink Shared Channel) transmission with repetitions (the first feature) and the second table (the second mapping table) is associated to a Msg3 PUSCH transmission with no repetitions (the second feature). In step 1120, the UE is provided a configuration for a first and second PRACH resources partitions. Here a first partition is associated to the first TDRA table and a second partition is associated to the second partition, and an RSRP threshold. The partition can be based on (i) PRACH preambles or (ii) PRACH preambles and ROs (RACH Occasions). In certain embodiments, the RSRP threshold that the UE uses to select a PRACH resources or preambles partition is associated to a Msg3 PUSCH transmission (step 1120). Here the Msg3 transmission can be with or without repetitions. The threshold can be same as the threshold rsrp (reference signal received power)-ThresholdSSB (Synchronization Signal Block) configured in RACH-ConfigCommon IE that the UE may use to select the SS (Synchronization Signal) block. In step 1130, the UE selects a TDRA table based on RSRP measurements and the configured threshold. Therefore, it is clear that a PRACH resource from among the plurality of PRACH resources is selected based on the received information indicating a mapping between the selected PRACH resource and a set of features of the plurality of sets of features.) and transmit a PRACH preamble using the selected PRACH resource, for indicating the set of features to the network node, (Cozzo, in Paragraphs [125]-[126], teaches that a gNB (such as the BS 102) can configure more than one TDRA (Time Domain Resource Assignment) table that a UE (such as the UE 116) can use to determine a resource allocation for a Msg3 PUSCH transmission, and configure partitions of PRACH resources associated to the TDRA tables. One table can be associated to Msg3 transmission without repetitions and one or more tables can be associated to Msg3 transmission with repetitions, or all tables can be associated to Msg3 with repetitions. A UE can select one of the configured TDRA tables and transmit a PRACH preamble in a RACH occasion (RO) or in a set of ROs selected from the PRACH resources associated to the selected TDRA table. The RO or the set of ROs can be used by any of the preambles of the different partitions. After reception of the PRACH preamble, the gNB can schedule a Msg3 transmission in an allocated resource, wherein resource allocation is done using the selected TDRA table. The UE then transmits a Msg3 PUSCH according to the indication of a PUSCH time resource allocation field in RAR from the selected table. A gNB (such as the UE 116) can also configure in a SIB one or more reference signal received power (RSRP) thresholds that a UE can use to select a TDRA table from the TDRA tables configured in the SIB. Therefore, it is clear that a PRACH preamble is transmitted by using the selected PRACH resource, for indicating the set of features to the network node.)
However, Cozzo does not explicitly teach that wherein the information that indicates the mappings between the plurality of PRACH resources and the plurality of sets of features comprises, for a PRACH resource of the plurality of PRACH resources, a set of flags that indicates a set of features mapped to the PRACH resource, wherein the set of features mapped to the PRACH resource comprises more than one feature; and wherein the set of flags includes a separate flag for each feature of said more than one feature.
Ishii teaches that wherein the information that indicates the mappings between the plurality of PRACH resources and the plurality of sets of features comprises, for a PRACH resource of the plurality of PRACH resources, a set of flags that indicates a set of features mapped to the PRACH resource, wherein the set of features mapped to the PRACH resource comprises more than one feature; and wherein the set of flags includes a separate flag for each feature of said more than one feature (Ishii, in section 1-1, 1-2, and 1-3, in Paragraphs [0051]-[0053], in Paragraphs [0071]-[0110], in Paragraphs [0131]-[0164], and in Paragraphs [0165]-[0176] teaches that in section 1-1 and in Paragraph [0051], UE receives necessary configuration information broadcasted as System Information from a current serving cell. The table in the section 1-1 show the PRACH resources and corresponding indicators (indices or flags) for multiple features and in Paragraphs [0071]-[0110], they are explained, respectively. In Paragraphs [0131]-[0164] in the section 1-2, based on the table, the selection of PRACH resource for PRACH preamble transmission is performed and the procedure of the selection is described in Paragraphs [0131]-[0164]. In this procedure, multiple resources and indices (flags) selected and their mapping are described based on the UE characteristics such as NB-IoT UE, BL (Bandwidth reduced Low Complexity) UE, or Normal UE (general UE). In the section 1-3 and in Paragraphs [0165]-[0176], by applying the selected resources, parameters and corresponding indices for multiple features, the procedure of PRACH preamble transmission performed by UE is described. According to this observation, multiple resources or parameters and corresponding indices (flags or indicators) for multiple features are selected for PRACH preamble transmission, based on the table in the broadcasted RRC System Information messages and applied for PRACH preamble transmission. Therefore, it is clear that the information that indicates the mappings between the plurality of PRACH resources and the plurality of sets of features comprises a set of flags that indicates a set of features mapped to the PRACH resource, where the set of features mapped to the PRACH resource comprises more than one feature and the set of flags includes a separate flag for each feature of said more than one feature.
It would have been obvious for one of ordinary skill in the art, before the effective filing date of the claimed invention, to combine Cozzo and Ishii to include the technique of wherein the information that indicates the mappings between the plurality of PRACH resources and the plurality of sets of features comprises, for a PRACH resource of the plurality of PRACH resources, a set of flags that indicates a set of features mapped to the PRACH resource, wherein the set of features mapped to the PRACH resource comprises more than one feature; and wherein the set of flags includes a separate flag for each feature of said more than one feature of Ishii in the system of Cozzo to provide methods and apparatus for performing a random access procedure (RACH) in wireless communications, providing a set of PRACH preambles to be reserved for upper layer to inform the network of a designated request/notification using the RACH process without performing a subsequent data transfer (Ishii, see Paragraphs [0002] and [0008]).).
Regarding claim 73, combination of Cozzo and Ishii teaches the features defined in the claims 72, -refer to the indicated claim for reference(s).
Cozzo further teaches that wherein each PRACH resource of the plurality of PRACH resources is mapped to a different one of the plurality of sets of features (Cozzo, in Fig. 11 and in Paragraphs [128]-[130], teaches that in step 1110, a UE (such as the UE 116: a wireless device) is provided a configuration for first and second TDRA (Time Domain Resource Allocation) tables, wherein the first table (the first mapping table) is associated to a Msg3 PUSCH (Physical Uplink Shared Channel) transmission with repetitions (the first feature) and the second table (the second mapping table) is associated to a Msg3 PUSCH transmission with no repetitions (the second feature). In step 1120, the UE is provided a configuration for a first and second PRACH resources partitions. Here a first partition is associated to the first TDRA table and a second partition is associated to the second partition, and an RSRP threshold. The partition can be based on (i) PRACH preambles or (ii) PRACH preambles and ROs(RACH Occasions). In certain embodiments, the RSRP threshold that the UE uses to select a PRACH resources or preambles partition is associated to a Msg3 PUSCH transmission (step 1120). Here the Msg3 transmission can be with or without repetitions. The threshold can be same as the threshold rsrp (reference signal received power)-ThresholdSSB (Synchronization Signal Block) configured in RACH-ConfigCommon IE that the UE may use to select the SS (Synchronization Signal) block. In step 1130, the UE selects a TDRA table based on RSRP measurements and the configured threshold. Therefore, it is clear that each PRACH resource of the plurality of PRACH resources is mapped to a different one of the plurality of sets of features.)
Regarding claim 74, combination of Cozzo and Ishii teaches the features defined in the claims 72, -refer to the indicated claim for reference(s).
Cozzo further teaches that wherein at least one of the plurality of sets of features is mapped to more than one of the plurality of PRACH resources (Cozzo, in Paragraph [135], teaches that when a partition of PRACH resources is associated to a UE type (for example, a PRACH resources or preambles partition A is for RedCap (Reduced Capability) UEs and a PRACH resources or preambles partition B is for non-RedCap UEs, or to a UE capability, for example, a PRACH resource partition A is for UEs supporting a coverage enhancement (CE) feature or a group of CE features and a PRACH resource partition B is for UEs not supporting the CE feature or the group of CE features of partition A), for PRACH retransmission after the initial PRACH transmission, the UE uses the same PRACH resource or a different resource from the same partition. A PRACH resource can comprise one or more PRACH preambles associated to one or more ROs (RACH Occasions), wherein the mapping between PRACH preambles and ROs can be a l-to-1 or a 1-to-N mapping. Alternatively, initial PRACH transmission and PRACH retransmission can be resources from different partitions. In this observation, it is clear that one feature set may be mapped more than one of the pluralities of PRACH resources.).
Regarding claim 75, combination of Cozzo and Ishii teaches the features defined in the claims 72, -refer to the indicated claim for reference(s).
Cozzo further teaches that wherein two or more of the plurality of PRACH resources, but not all of the plurality of PRACH resources, are mapped to a same set of features (Cozzo, in Paragraph [135], teaches that initial PRACH transmission and PRACH retransmission can be resources from different partitions. For example, when a UE is provided a configuration for a first and second PRACH resources or preambles partitions, wherein the first PRACH resources or preambles partition is associated to non-CE features and the second PRACH resource partition is associated to CE features, if the initial transmission with a PRACH resource from the first partition fails, the UE can use a PRACH resource from the second partition for retransmission. Whether initial PRACH transmission and PRACH retransmission use same or different PRACH resources from different PRACH resources or preambles partitions can be configured in SIB. Therefore, it is clear that two or more of the plurality of PRACH resources, but not all of the plurality of PRACH resources, are mapped to a same set of features.).
Regarding claim 76, combination of Cozzo and Ishii teaches the features defined in the claims 72, -refer to the indicated claim for reference(s).
Cozzo further teaches that wherein a PRACH resource is a random access channel occasion (RO) (Cozzo, in Paragraphs [125]-[126], teaches that a gNB (such as the BS 102) can configure more than one TDRA (Time Domain Resource Assignment) table that a UE (such as the UE 116) can use to determine a resource allocation for a Msg3 PUSCH transmission, and configure partitions of PRACH resources associated to the TDRA tables. One table can be associated to Msg3 transmission without repetitions and one or more tables can be associated to Msg3 transmission with repetitions, or all tables can be associated to Msg3 with repetitions. A UE can select one of the configured TDRA tables and transmit a PRACH preamble in a RACH occasion (RO) or in a set of ROs selected from the PRACH resources associated to the selected TDRA table. The RO or the set of ROs can be used by any of the preambles of the different partitions. After reception of the PRACH preamble, the gNB can schedule a Msg3 transmission in an allocated resource, wherein resource allocation is done using the selected TDRA table. The UE then transmits a Msg3 PUSCH according to the indication of a PUSCH time resource allocation field in RAR from the selected table. A gNB (such as the UE 116) can also configure in a SIB one or more reference signal received power (RSRP) thresholds that a UE can use to select a TDRA table from the TDRA tables configured in the SIB. Therefore, it is clear that a PRACH preamble is transmitted by using the selected PRACH resource, for indicating the set of features to the network node. Therefore, it is clear that a PRACH resource is a random access channel occasion (RO).).
Regarding claim 78, Cozzo teaches that a method performed by a network node, the method comprising: sending, to a wireless communication device, information that indicates mappings between a plurality of Physical Random Access Channel (PRACH) resources and a plurality of sets of features, (Cozzo, in Paragraph [125], teaches that a gNB (such as the BS 102) can configure more than one TDRA table that a UE (such as the UE 116) can use to determine a resource allocation for a Msg3 PUSCH transmission, and configure partitions of PRACH resources associated to the TDRA tables (mapping tables). One table can be associated to Msg3 transmission without repetitions and one or more tables can be associated to Msg3 transmission with repetitions, or all tables can be associated to Msg3 with repetitions. A UE can select one of the configured TDRA tables and transmit a PRACH preamble in a RACH occasion (RO) or in a set of ROs selected from the PRACH resources associated to the selected TDRA table. The RO or the set of ROs can be used by any of the preambles of the different partitions. Therefore, it is clear that a base station may send, to a wireless communication device, information that indicates mappings between a plurality of PRACH resources and a plurality of sets of features.) wherein at least one of the plurality of sets of features comprises more than one feature (Cozzo, in Fig. 14 and in Paragraphs [143]-[145], teaches that the method 1400 in Fig. 14 describes an example procedure for a UE to determine a resource allocation in time domain for Msg3 PUSCH transmission. In step 1410, a UE (such as the UE 116) is configured a TDRA table. The TDRA table includes an indication of a number of repetitions in each row. In step 1420, the UE is indicated a value m in a RAR (Random Access Response) UL grant, wherein the value provides a row index m+1 to the configured TDRA table. In step 1430, UE determines to transmit Msg3 PUSCH (Physical Uplink Shared Channel) with a number of repetitions indicated by an entry in row m + 1 of the configured table based on RSRP (Reference Signal Received Power) measurements and configured threshold. The RSRP measurements can be based on an SS/PBCH block or on a CSI-RS or a RAR or a combination of some or all of these receptions. In step 1440, the UE transmits a Msg3 PUSCH with repetitions using resources determined from the configured table. In certain embodiments, a gNB (such as the BS 102) can configures a UE (such as the UE 116) to a single TDRA table for Msg3 transmission, wherein the TDRA table includes an indication of a number of repetitions in each row and also configure PRACH resources or preambles partitions corresponding to Msg3 PUSCH transmission with or without repetitions and an RSRP threshold. Based on RSRP measurements and the configured RSRP threshold, wherein the RSRP measurements can be based on an SS/PBCH block or on a CSI-RS, wherein the SS/PBCH can be a CD (Cell Defining) SSB or an NCD (Non-Cell Defining)-SSB, the UE selects a PRACH resources or preambles partition and transmits Msg3 PUSCH. Therefore, it is clear that a set of features may have more than one feature.)
However, Cozzo does not explicitly teach that wherein the information that indicates the mappings between the plurality of PRACH resources and the plurality of sets of features comprises, for a PRACH resource of the plurality of PRACH resources, a set of flags that indicates a set of features mapped to the PRACH resource, wherein the set of features mapped to the PRACH resource comprises more than one feature; and wherein the set of flags includes a separate flag for each feature of said more than one feature.
Ishii teaches that wherein the information that indicates the mappings between the plurality of PRACH resources and the plurality of sets of features comprises, for a PRACH resource of the plurality of PRACH resources, a set of flags that indicates a set of features mapped to the PRACH resource, wherein the set of features mapped to the PRACH resource comprises more than one feature; and wherein the set of flags includes a separate flag for each feature of said more than one feature (Ishii, in section 1-1, 1-2, and 1-3, in Paragraphs [0051]-[0053], in Paragraphs [0071]-[0110], in Paragraphs [0131]-[0164], and in Paragraphs [0165]-[0176] teaches that in section 1-1 and in Paragraph [0051], UE receives necessary configuration information broadcasted as System Information from a current serving cell. The table in the section 1-1 show the PRACH resources and corresponding indicators (indices or flags) for multiple features and in Paragraphs [0071]-[0110], they are explained, respectively. In Paragraphs [0131]-[0164] in the section 1-2, based on the table, the selection of PRACH resource for PRACH preamble transmission is performed and the procedure of the selection is described in Paragraphs [0131]-[0164]. In this procedure, multiple resources and indices (flags) selected and their mapping are described based on the UE characteristics such as NB-IoT UE, BL (Bandwidth reduced Low Complexity) UE, or Normal UE (general UE). In the section 1-3 and in Paragraphs [0165]-[0176], by applying the selected resources, parameters and corresponding indices for multiple features, the procedure of PRACH preamble transmission performed by UE is described. According to this observation, multiple resources or parameters and corresponding indices (flags or indicators) for multiple features are selected for PRACH preamble transmission, based on the table in the broadcasted RRC System Information messages and applied for PRACH preamble transmission. Therefore, it is clear that the information that indicates the mappings between the plurality of PRACH resources and the plurality of sets of features comprises a set of flags that indicates a set of features mapped to the PRACH resource, where the set of features mapped to the PRACH resource comprises more than one feature and the set of flags includes a separate flag for each feature of said more than one feature.
It would have been obvious for one of ordinary skill in the art, before the effective filing date of the claimed invention, to combine Cozzo and Ishii to include the technique of wherein the information that indicates the mappings between the plurality of PRACH resources and the plurality of sets of features comprises, for a PRACH resource of the plurality of PRACH resources, a set of flags that indicates a set of features mapped to the PRACH resource, wherein the set of features mapped to the PRACH resource comprises more than one feature; and wherein the set of flags includes a separate flag for each feature of said more than one feature of Ishii in the system of Cozzo to provide methods and apparatus for performing a random access procedure (RACH) in wireless communications, providing a set of PRACH preambles to be reserved for upper layer to inform the network of a designated request/notification using the RACH process without performing a subsequent data transfer (Ishii, see Paragraphs [0002] and [0008]).).
Regarding claim 79, combination of Cozzo and Ishii teaches the features defined in the claims 78, -refer to the indicated claim for reference(s).
Cozzo further teaches that further comprising: receiving a PRACH preamble using a selected PRACH resource, the sent information indicating a mapping between the selected PRACH resource and a set of features of the plurality of sets of features (Cozzo, in Paragraphs [125]-[126], teaches that a gNB (such as the BS 102) can configure more than one TDRA (Time Domain Resource Assignment) table that a UE (such as the UE 116) can use to determine a resource allocation for a Msg3 PUSCH transmission, and configure partitions of PRACH resources associated to the TDRA tables. One table can be associated to Msg3 transmission without repetitions and one or more tables can be associated to Msg3 transmission with repetitions, or all tables can be associated to Msg3 with repetitions. A UE can select one of the configured TDRA tables and transmit a PRACH preamble in a RACH occasion (RO) or in a set of ROs selected from the PRACH resources associated to the selected TDRA table. The RO or the set of ROs can be used by any of the preambles of the different partitions. After reception of the PRACH preamble, the gNB can schedule a Msg3 transmission in an allocated resource, wherein resource allocation is done using the selected TDRA table. The UE then transmits a Msg3 PUSCH according to the indication of a PUSCH time resource allocation field in RAR from the selected table. A gNB (such as the UE 116) can also configure in a SIB one or more reference signal received power (RSRP) thresholds that a UE can use to select a TDRA table from the TDRA tables configured in the SIB. Therefore, it is clear that a base station may receive a PRACH preamble using a selected PRACH resource and the sent information indicating a mapping between the selected PRACH resource and a set of features of the plurality of sets of features.).
Regarding claim 80, combination of Cozzo and Ishii teaches the features defined in the claims 79, -refer to the indicated claim for reference(s).
Cozzo further teaches that further comprising: determining an indicated set of features based on the PRACH resource in which the PRACH preamble was received, and optionally which PRACH preamble was received (Cozzo, in Paragraphs [125]-[126], teaches that a gNB (such as the BS 102) can configure more than one TDRA (Time Domain Resource Assignment) table that a UE (such as the UE 116) can use to determine a resource allocation for a Msg3 PUSCH transmission, and configure partitions of PRACH resources associated to the TDRA tables. One table can be associated to Msg3 transmission without repetitions and one or more tables can be associated to Msg3 transmission with repetitions, or all tables can be associated to Msg3 with repetitions. A UE can select one of the configured TDRA tables and transmit a PRACH preamble in a RACH occasion (RO) or in a set of ROs selected from the PRACH resources associated to the selected TDRA table. The RO or the set of ROs can be used by any of the preambles of the different partitions. After reception of the PRACH preamble, the gNB can schedule a Msg3 transmission in an allocated resource, wherein resource allocation is done using the selected TDRA table. The UE then transmits a Msg3 PUSCH according to the indication of a PUSCH time resource allocation field in RAR from the selected table. A gNB (such as the UE 116) can also configure in a SIB one or more reference signal received power (RSRP) thresholds that a UE can use to select a TDRA table from the TDRA tables configured in the SIB. Therefore, it is clear that a base station may determine an indicated set of features based on the PRACH resource (by using the selected TDRA table) in which the PRACH preamble was received, and optionally which PRACH preamble was received.).
Regarding claim 81, Cozzo teaches that a network node comprising processing circuitry configured to cause the network node to: (Cozzo, in Fig. 2 and in Paragraphs [59]-[61], teaches that as shown in Fig. 2, the BS (Base Station) 102 includes multiple antennas 205a-205n, multiple radio frequency (RF) transceivers 210a-210n, transmit (TX) processing circuitry 215, and receive (RX) processing circuitry 220. The BS 102 also includes a controller/processor 225, a memory 230, and a backhaul or network interface 235. The RF transceivers 210a-210n receive, from the antennas 205a-205n, incoming RF signals, such as signals transmitted by UEs in the wireless network 100. The RF transceivers 210a-210n down-convert the incoming RF signals to generate IF or baseband signals. The IF or baseband signals are sent to the RX processing circuitry 220, which generates processed baseband signals by filtering, decoding, and/or digitizing the baseband or IF signals. The TX processing circuitry 215 receives analog or digital data from the controller/processor 225. The TX processing circuitry 215 encodes, multiplexes, and/or digitizes the outgoing baseband data to generate processed baseband or IF signals. Therefore, it is clear that a network node may comprise processing circuitry configured to cause the network node to perform processing.) send, to a wireless communication device, information that indicates mappings between a plurality of Physical Random Access Channel (PRACH) resources and a plurality of sets of features, (Cozzo, in Paragraph [125], teaches that a gNB (such as the BS 102) can configure more than one TDRA table that a UE (such as the UE 116) can use to determine a resource allocation for a Msg3 PUSCH transmission, and configure partitions of PRACH resources associated to the TDRA tables (mapping tables). One table can be associated to Msg3 transmission without repetitions and one or more tables can be associated to Msg3 transmission with repetitions, or all tables can be associated to Msg3 with repetitions. A UE can select one of the configured TDRA tables and transmit a PRACH preamble in a RACH occasion (RO) or in a set of ROs selected from the PRACH resources associated to the selected TDRA table. The RO or the set of ROs can be used by any of the preambles of the different partitions. Therefore, it is clear that a base station may send, to a wireless communication device, information that indicates mappings between a plurality of PRACH resources and a plurality of sets of features.)
However, Cozzo does not explicitly teach that wherein the information that indicates the mappings between the plurality of PRACH resources and the plurality of sets of features comprises, for a PRACH resource of the plurality of PRACH resources, a set of flags that indicates a set of features mapped to the PRACH resource, wherein the set of features mapped to the PRACH resource comprises more than one feature; and wherein the set of flags includes a separate flag for each feature of said more than one feature.
Ishii teaches that wherein the information that indicates the mappings between the plurality of PRACH resources and the plurality of sets of features comprises, for a PRACH resource of the plurality of PRACH resources, a set of flags that indicates a set of features mapped to the PRACH resource, wherein the set of features mapped to the PRACH resource comprises more than one feature; and wherein the set of flags includes a separate flag for each feature of said more than one feature (Ishii, in section 1-1, 1-2, and 1-3, in Paragraphs [0051]-[0053], in Paragraphs [0071]-[0110], in Paragraphs [0131]-[0164], and in Paragraphs [0165]-[0176] teaches that in section 1-1 and in Paragraph [0051], UE receives necessary configuration information broadcasted as System Information from a current serving cell. The table in the section 1-1 show the PRACH resources and corresponding indicators (indices or flags) for multiple features and in Paragraphs [0071]-[0110], they are explained, respectively. In Paragraphs [0131]-[0164] in the section 1-2, based on the table, the selection of PRACH resource for PRACH preamble transmission is performed and the procedure of the selection is described in Paragraphs [0131]-[0164]. In this procedure, multiple resources and indices (flags) selected and their mapping are described based on the UE characteristics such as NB-IoT UE, BL (Bandwidth reduced Low Complexity) UE, or Normal UE (general UE). In the section 1-3 and in Paragraphs [0165]-[0176], by applying the selected resources, parameters and corresponding indices for multiple features, the procedure of PRACH preamble transmission performed by UE is described. According to this observation, multiple resources or parameters and corresponding indices (flags or indicators) for multiple features are selected for PRACH preamble transmission, based on the table in the broadcasted RRC System Information messages and applied for PRACH preamble transmission. Therefore, it is clear that the information that indicates the mappings between the plurality of PRACH resources and the plurality of sets of features comprises a set of flags that indicates a set of features mapped to the PRACH resource, where the set of features mapped to the PRACH resource comprises more than one feature and the set of flags includes a separate flag for each feature of said more than one feature.
It would have been obvious for one of ordinary skill in the art, before the effective filing date of the claimed invention, to combine Cozzo and Ishii to include the technique of wherein the information that indicates the mappings between the plurality of PRACH resources and the plurality of sets of features comprises, for a PRACH resource of the plurality of PRACH resources, a set of flags that indicates a set of features mapped to the PRACH resource, wherein the set of features mapped to the PRACH resource comprises more than one feature; and wherein the set of flags includes a separate flag for each feature of said more than one feature of Ishii in the system of Cozzo to provide methods and apparatus for performing a random access procedure (RACH) in wireless communications, providing a set of PRACH preambles to be reserved for upper layer to inform the network of a designated request/notification using the RACH process without performing a subsequent data transfer (Ishii, see Paragraphs [0002] and [0008]).).
Claims 71 and 77 are rejected under U.S.C. 103 as being unpatentable Cozzo, Carmela and et. al. (Int. Pub. No.: WO 2022186614 A1, hereinafter “Cozzo”) in a view of Atsushi Ishii (USPub No.: US 20180317263 A1, hereinafter “Ishii”) and further in a view of Rastegardoost, Nazanin and et. al. (Int. Pub. No.: WO 2022133357 A1, hereinafter “Rastegardoost”).
Regarding claim 71, combination of Cozzo and Ishii teaches the features defined in the claims 62, -refer to the indicated claim for reference(s).
However, combination of Cozzo and Ishii does not explicitly teach that wherein a set of features of the plurality of sets of features comprises at least one of: reduced capabilities, or coverage enhancement, or small data transmissions, or coverage enhancement, or slicing.
Rastegardoost teaches that wherein a set of features of the plurality of sets of features comprises at least one of: reduced capabilities, or small data transmissions, or coverage enhancement, or slicing (Rastegardoost, in Fig. 23 and in Paragraph [0311], teaches that as shown in FIG. 23, RACH partitioning may be considered for early identification of multiple new and/or different features, such as RedCap, Small Data Transmission (SDT), coverage enhancement, and slicing. For example, RRC/SIB 1 may configure a first RACH configuration for RedCap (Reduce Capability) to indicate reduced capabilities to the network in MSG 1 so that the network can adapt subsequent transmissions. For example, RRC(Radio Resource Control)/SIB 1 (System Information Block 1) may configure a second RACH configuration for SDT (Small Data Transmission) to enable the UE to request a larger MSG3 size (or MSGA size in case of 2-step RA). For example, RRC/SIB 1 may configure a third RACH configuration for coverage enhancement to enable the UE to indicate need for coverage enhancement (esp. for request of MSG3 repetition). For example, RRC/SIB 1 may configure a fourth RACH configuration for slicing to indicate high priority slice to the network and to achieve slice isolation also for RACH. Therefore, it is clear that a set of features of the plurality of sets of features comprises at least one of reduced capabilities, or small data transmissions, or coverage enhancement, or slicing.
It would have been obvious for one of ordinary skill in the art, before the effective filing date of the claimed invention, to combine Cozzo, Ishii, and Rastegardoost to include the technique of wherein a set of features of the plurality of sets of features comprises at least one of: reduced capabilities, or small data transmissions, or coverage enhancement, or slicing of Rastegardoost in the system of combination of Cozzo and Ishii to provide an improved design in initial access, more specifically random access response reception for UE having various type of capabilities, such as RedCap (Reduced Capability) UE, NR (New Radio)-Light UE and/or enhanced UE, to enable a dedicated signaling based on the respective features of the UE such as coverage recovery/enhancement and/or small data transmission and/or a combination thereof, while a signal collision with legacy UEs is avoided (Rastegardoost, see Paragraphs [0294], [0295] and [0298]).).
Regarding claim 77, combination of Cozzo and Ishii teaches the features defined in the claims 72, -refer to the indicated claim for reference(s).
However, combination of Cozzo and Ishii does not explicitly teach that wherein a set of features of the plurality of sets of features comprises at least one of: reduced capabilities, or coverage enhancement, or small data transmissions, or coverage enhancement, or slicing.
Rastegardoost teaches that wherein a set of features of the plurality of sets of features comprises at least one of: reduced capabilities, or small data transmissions, or coverage enhancement, or slicing (Rastegardoost, in Fig. 23 and in Paragraph [0311], teaches that as shown in FIG. 23, RACH partitioning may be considered for early identification of multiple new and/or different features, such as RedCap, Small Data Transmission (SDT), coverage enhancement, and slicing.
