DETAILED ACTION
a. Claims 1-20 in the present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA :
b. This is a third non final action on the merits based on Applicant’s claims submitted on 10/27/2025.
Response to Arguments
Regarding claims 1-3, 5-8, 12-15, 17, 19, and 20 previously rejected under 35 U.S.C. § 103, Applicant's arguments, see “The Office Action cited Shen to remedy the deficiencies of Yang. However, Shen also does not disclose a Msg3 that includes "a medium access control (MAC) field indicating repetitions for a hybrid automatic repeat request acknowledgment (HARQ-ACK) of a Message4 of the random access procedure," as recited in claim 1. Indeed, Shen does not mention any random access procedure, much less a Msg3. Therefore, Shen cannot remedy Yang's deficiencies.” on page 4, filed on 10/27/2025, with respect to Shen et al. US Pub 2023/0388061 (hereinafter “Shen”), have been fully considered and are persuasive. Therefore, the previous rejection has been withdrawn. However, upon further consideration, a new ground of rejection is made in view of Xiong et al. US Pub 2021/0251016 (hereinafter “Xiong”), as combined with previously applied reference Yang. See section Claim Rejections - 35 USC § 103 below for complete details.
Claim Rejections - 35 USC § 103
The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action:
A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102 of this title, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made.
In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status.
Claims 1-3, 5-11, and 12-20 are rejected under 35 U.S.C. 103 as being unpatentable over Yang et al. Foreign Patent WO2021/062209 (hereinafter “Yang”), and in view of Xiong et al. US Pub 2021/0251016 (hereinafter “Xiong”).
Regarding claim 1
Yang discloses a method (“The method may include determining a Physical Uplink Control Channel (PUCCH) resource for a PUCCH transmission prior to receiving a dedicated PUCCH resource configuration, determining a repetition level for the PUCCH transmission, and transmitting the PUCCH transmission, on at least the PUCCH resource, according to the repetition level.” [0004]) comprising:
transmitting, by a wireless device (i.e. “UE115-A” in Fig. 2; [0077]) and for a random access procedure (“As seen in FIG. 2, a typical RACH procedure may involve four transmissions.” [0077]), a Message3 (“the UE 115-a may then transmit Msg3 on PUSCH at 215 using resources scheduled by the uplink grant of Msg2” [0078]; see Fig. 2) comprising a medium access control (MAC) field for a hybrid automatic repeat request acknowledgment (HARQ- ACK) (“The MAC layer may also use hybrid automatic repeat request (HARQ) to provide retransmission at the MAC layer to improve link efficiency.” [0060]) of a Message4 of the random access procedure (“The base station 105-a may then transmit a contention resolution message referred to as Msg4 on the PDCCH or PDSCH at 220. The UE 115-a then sends a HARQ-ACK message at 225 to acknowledge whether Msg4 was received at the UE 115-a or not.” [0078]; see Fig. 2).
Yang does not specifically teach a MAC field indicating repetitions for a hybrid automatic repeat request acknowledgment (HARQ- ACK) of a Message4 of the random access procedure.
In an analogous art, Xiong discloses a MAC field indicating repetitions for a hybrid automatic repeat request acknowledgment (HARQ- ACK) of a Message4 of the random access procedure (“In one embodiment, a repetition level of the PUCCH carrying HARQ-ACK response of Msg4 can be predefined or configured by a higher layer via MSI, RMSI, OSI or RRC signaling, or dynamically indicated in the DCI format 1_0 for scheduling Msg4, by a MAC CE of Msg4, or a combination thereof.” [0092] and furthermore “In another embodiment, the repetition level of the PUCCH carrying the HARQ-ACK response of Msg4 can be determined in accordance with that of the PRACH preamble and/or that of Msg4 transmission and/or Msg3 PUSCH transmission for the contention based 4-step RACH procedure, or a combination thereof.” [0101]);
Before the effective filling date of the claimed invention, it would have been obvious to one of ordinary skill in the art to modify Yang’s method for determining a repetition level for the PUCCH transmission, to include Xiong’s method for determining a physical uplink control channel (PUCCH) repetition factor, in order to efficiently determine an appropriate repetition level for HARQ-ACK repetitions (Xiong [0051]). Thus, a person of ordinary skill would have appreciated the ability to incorporate Xiong’s method for determining a physical uplink control channel (PUCCH) repetition factor into Yang’s method for determining a repetition level for the PUCCH transmission since the claimed invention is merely a combination of old elements, and in the combination each element merely would have performed the same function as it did separately, and one of ordinary skill in the art would have recognized that the results of the combination were predictable.
Regarding claim 2
Yang, as modified by Xiong, previously discloses the method of claim 1,
Yang further discloses further comprising receiving the Message4 (“receiving a fourth message (MSG4) comprising a contention resolution message on the Physical Downlink Control Channel (PDCCH) or Physical Downlink Shared Channel (PDSCH)” [0029]).
Regarding claim 3
Yang, as modified by Xiong, previously discloses the method of claim 2,
Yang further discloses further comprising transmitting, via physical uplink control channel (PUCCH), repetitions for the HARQ-ACK of the Message4 (“As described in the present disclosure, a UE 115 may apply repetition to PUCCH transmissions that do not have dedicated PUCCH resources configured. For example, in response to receiving Msg4 or MsgB during random access procedures, the UE 115 may transmit HARQ-ACK messages using a particular repetition level or factor on PUCCH resources prior to receiving configuration of dedicated PUCCH resources.” [0083).
Regarding claim 5
Yang, as modified by Xiong, previously discloses the method of claim 1,
Yang further discloses further comprising receiving a random access response (“receiving a second message (MSG2) comprising a random access response (RAR) that includes scheduling for a Physical Uplink Shared Channel (PUSCH) transmission” [0029]; see Fig. 2).

Yang further discloses wherein the random access response comprises a scheduling grant for the Message3 (After receiving Msg2 or the RAR, the UE 115-a may then transmit Msg3 on PUSCH at 215 using resources scheduled by the uplink grant of Msg2.“ [0078] and furthermore “an uplink grant for the UE’s 115-a Msg3 transmission on the uplink” [0077]).
Regarding claim 7
Yang, as modified by Xiong, previously discloses the method of claim 1,
Yang further discloses wherein the Message3 Is transmitted via a physical uplink shared channel (PUSCH) (“transmitting a third message (MSG3) comprising the PUSCH transmission” [0029] and furthermore “After receiving Msg2 or the RAR, the UE 115-a may then transmit Msg3 on PUSCH at 215 using resources scheduled by the uplink grant of Msg2” [0078]).
Regarding claim 8
Yang, as modified by Xiong, previously discloses the method of claim 1,
Yang further discloses wherein the Message3 comprises a contention resolution identity of the wireless device (“The random access messages may include contention resolution messages (e.g., MsgA or Msg4) and HARQ-ACK transmissions, in response to reception of the contention resolution messages (i.e. “Message3”), transmitted by UE 900 to gNB 1000.” [0097]).

one or more reference signals (“measured Reference Signal Receive Power (RSRP)” [0082]); and
one or more reference signal received power (RSRP) thresholds for determining repetitions of the HARQ-ACK of the Message4 (“Further, if the repetition level of the PRACH transmission is less than or equal to a configured or predefined threshold or the measured RSRP is larger than or equal to a configured or predefined threshold, one repetition level is configured via SIB1 or RMSI from the first set of repetition levels for the PUCCH carrying the HARQ-ACK response of Msg4; if the repetition level of the PRACH transmission is larger than a configured or predefined threshold or the measured RSRP is less than or equal to a configured or predefined threshold, another repetition level is configured via SIB1 or RMSI from the second set of repetition levels for the PUCCH carrying the HARQ-ACK response of Msg4.” [0103]).
Regarding claim 10
Yang, as modified by Xiong, previously discloses the method of claim 9,
Xiong further discloses further comprising determining the repetitions of the HARQ-ACK of the Message4 based on a radio link quality (i.e. “measured RSRP value”) of the one or more reference signals (“In another example, the repetition level of the PUCCH carrying the HARQ-ACK response of Msg4 can be determined in accordance with the repetition level of the PRACH transmission or the measured RSRP value.” [0103]).
Regarding claim 11
Yang, as modified by Xiong, previously discloses the method of claim 10,
Xiong further discloses further comprising determining the repetitions of the HARQ-ACK of the Message4 based on comparing the radio link quality of the one or more reference signals with the one or more RSRP thresholds (“Further, if the repetition level of the PRACH transmission is less than or equal to a configured or predefined threshold or the measured RSRP is larger than or equal to a configured or predefined threshold, one repetition level is configured via SIB1 or RMSI from the first set of repetition levels for the PUCCH carrying the HARQ-ACK response of Msg4; if the repetition level of the PRACH transmission is larger than a configured or predefined threshold or the measured RSRP is less than or equal to a configured or predefined threshold, another repetition level is configured via SIB1 or RMSI from the second set of repetition levels for the PUCCH carrying the HARQ-ACK response of Msg4.” [0103]).
Regarding claim 12
Yang, as modified by Xiong, previously discloses the method of claim 1,
Yang further discloses wherein the Message4 indicates one or more uplink resources for a plurality of repetitions of the HARQ-ACK of the Message4 (“the UE 115 may determine the uplink resources to use for Msg4 transmission based on the received grant” [0084]).
Regarding claim 13
Yang, as modified by Xiong, previously discloses the method of claim 12,
Yang further discloses further comprising transmitting, via the one or more uplink resources (i.e. “PUCCH resources”) and a physical uplink control channel (i.e. “PUCCH”), the plurality of repetitions of the HARQ-ACK of the Message4 (“repetitions for PUCCH transmissions scheduled using dedicated PUCCH resources may typically be supported, while for PUCCH transmissions scheduled prior to configuration of dedicated PUCCH resources, repetition may not be supported. Examples of PUCCH transmissions that may occur without or prior to configuration of dedicated PUCCH resources may include HARQ- ACK messages in response to Msg4 or MsgB reception during random access procedures.” [0082]).
Regarding claim 14
Yang, as modified by Xiong, previously discloses the method of claim 1,
Yang further discloses wherein the Message4 indicates one or more uplink resources (i.e. “PUCCH resources”) for a single repetition of the HARQ-ACK of the Message4 (“with respect to FIG. 3, the HARQ-ACK message acknowledging the contention resolution message (Msg4 or MsgB) may be transmitted prior to the UE 115 receiving dedicated PUCCH resource configuration. In particular, the UE 115 may transmit the HARQ-ACK message on PUCCH resources that are assigned via indication in system information (e.g., SIB 1).” [0081]).
Regarding claim 15
Yang, as modified by Xiong, previously discloses the method of claim 14,
Yang further discloses further comprising transmitting, via the one or more uplink resources and a physical uplink control channel, the single repetition of the HARQ-ACK of the Message4 (“repetitions for PUCCH transmissions scheduled using dedicated PUCCH resources may typically be supported, while for PUCCH transmissions scheduled prior to configuration of dedicated PUCCH resources, repetition may not be supported. Examples of PUCCH transmissions that may occur without or prior to configuration of dedicated PUCCH resources may include HARQ- ACK messages in response to Msg4 or MsgB reception during random access procedures.” [0082]).
Regarding claim 16
Yang, as modified by Xiong, previously discloses the method of claim 1,
Xiong further discloses wherein the MAC field indicates a capability of the wireless device in using repetitions for HARQ of the Message4 (“In one option, a set of repetition levels for a PUCCH carrying a HARQ-ACK response of Msg4 can be predefined or configured by SIB1 or the RMSI, e.g., {2, 4, 8, 16}. Then, the 2-bit field in the DCI for scheduling Msg4 can be used to indicate which repetition level is used for the transmission of the PUCCH. Alternatively, two bits in a MAC CE of Msg4 can be used to indicate which repetition level is used for the transmission of the PUCCH.” [0093]).
Regarding claim 17
Yang discloses a wireless device (“UE 900” in Fig. 9; [0106]), comprising:
one or more processors (“controller/processor 880” in Fig. 9; [0106]); and
memory (“memory 882” in Fig. 9; [0106]) storing instructions that, when executed by the one or more processors, cause the wireless device at least to perform: transmitting, for a random access procedure, a Message3 comprising a medium access control (MAC) field indicating repetitions for a hybrid automatic repeat request acknowledgment (HARQ-ACK) of a Message4 of the random access procedure.
The scope and subject matter of apparatus claim 17 is drawn to the apparatus of using the corresponding method claimed in claim 1. Therefore apparatus claim 17 corresponds to method claim 1 and is rejected for the same reasons of obviousness as used in claim 1 rejection above.
Regarding claim 18
The wireless device of claim 17, wherein the instructions further cause the wireless device to perform receiving, from a base station, configuration parameters indicating: one or more reference signals; and one or more reference signal received power (RSRP) thresholds for determining repetitions of the HARQ-ACK of the Message4.
The scope and subject matter of apparatus claim 18 is drawn to the apparatus of using the corresponding method claimed in claim 9. Therefore apparatus claim 18 corresponds to method claim 9 and is rejected for the same reasons of obviousness as used in claim 9 rejection above.
Regarding claim 19
The wireless device of claim 17, wherein the Message4 indicates one or more uplink resources for a plurality of repetitions of the HARQ-ACK of the Message4 or the Message4 indicates one or more uplink resources for a single repetition of the HARQ-ACK of the Message.
The scope and subject matter of apparatus claim 19 is drawn to the apparatus of using the corresponding method claimed in claims 12 and 14. Therefore apparatus claim 19 corresponds to method claims 12 and 14 and is rejected for the same reasons of obviousness as used in claims 12 and 14 rejections above.
Regarding claim 20
A non-transitory computer-readable medium comprising instructions that, when executed by one or more processors of a device, cause the device to perform:
transmitting, for a random access procedure, a Message3 comprising a medium access control (MAC) field indicating repetitions for a hybrid automatic repeat request acknowledgment (HARQ-ACK) of a Messageé4 of the random access procedure.
The scope and subject matter of non-transitory computer readable medium claim 20 is drawn to the computer program product of using the corresponding method claimed in claim 1. Therefore computer program product claim 20 corresponds to method claim 1 and is rejected for the same reasons of obviousness as used in claim 1 rejection above.
Claim 4 is rejected under 35 U.S.C. 103 as being unpatentable over Yang, in view of Xiong, and further in view of Lee et al. US 2021/0297909 (hereinafter “Lee”).
Regarding claim 4
Yang, as modified by Xiong, previously discloses the method of claim 2,
Yang further discloses wherein the Message4 (“a fourth message (MSG4) comprising a contention resolution message on the Physical Downlink Control Channel (PDCCH) or Physical Downlink Shared Channel (PDSCH)” [0029]) Is a physical downlink shared channel (i.e. “PDSCH”) reception comprising a contention resolution identity (i.e. “contention resolution message”) of the wireless device.
Yang and Xiong do not specifically teach that Message4 comprising a contention resolution identity of the wireless device.
In an analogous art, Lee discloses Message4 comprising a contention resolution identity of the wireless device (“if the MAC PDU (e.g., in a PDSCH of Msg4) contains a UE Contention Resolution Identity MAC control element” [0097]).
Before the effective filling date of the claimed invention, it would have been obvious to one of ordinary skill in the art to modify Yang’s method for determining a repetition level for the PUCCH transmission, as modified by Xiong, to include Lee’s method for performing a handover procedure in a wireless communication system, in order to perform contention-based random access procedure (Lee [0073]). Thus, a person of ordinary skill would have appreciated the ability to incorporate Lee’s method for performing a handover procedure in a wireless communication system into Yang’s method for determining a repetition level for the PUCCH transmission since the claimed invention is merely a combination of old elements, and in the combination each element merely would have performed the same function as it did separately, and one of ordinary skill in the art would have recognized that the results of the combination were predictable.
