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, 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.
This application currently names joint inventors. In considering patentability of the claims the examiner presumes that the subject matter of the various claims was commonly owned as of the effective filing date of the claimed invention(s) absent any evidence to the contrary. Applicant is advised of the obligation under 37 CFR 1.56 to point out the inventor and effective filing dates of each claim that was not commonly owned as of the effective filing date of the later invention in order for the examiner to consider the applicability of 35 U.S.C. 102(b)(2)(C) for any potential 35 U.S.C. 102(a)(2) prior art against the later invention.
Claims 25-26, 32, and 34-37 are rejected under 35 U.S.C. 103 as being unpatentable over Fan et al. (US 2022/0264561 A1; hereinafter Fan) in view of Yu et al. (US 2021/0051668 A1; hereinafter Yu) further in view of Venugopal et al. (US 2021/0105805 A1; hereinafter Venugopal).
Regarding claims 25, Fan teaches a method performed by a User Equipment (UE) (Fig. 1, illustrates a Terminal device; ¶ [0054] The system architecture includes a terminal device.),
the method comprising:
receiving, from a network node (read as network device), a higher layer configuration (read as RRC) or a Medium Access Control-Control Element (MAC-CE) message that associates a sounding reference signal (SRS) resource or an SRS resource set comprising at least one SRS resource configured with a parameter usage that is set to "codebook" or "nonCodebook", with a control resource set pool index (¶ [0079] The resource may be an SRS.; ¶ [0080] The resource is configured by using RRC signaling.; ¶ [0186] An SRS for codebook-based uplink transmission (an SRS in an SRS resource set whose usage parameter is codebook).; ¶ [0191] The spatial relation that is delivered by the network device may be carried in downlink signaling, such as RRC signaling or media access control element (MAC-CE) signaling.; ¶ [0252] One SRS may be associated with one CORESET. Each CORESET may be associated with a CORESETPoolIndex.),
wherein the control resource set pool index is a higher-layer parameter in a configuration of a control resource set (CORESET) (¶ [0141] The CORESET may be configured by using a control-resource set parameter in RRC signaling.; ¶ [0258] The network device may configure a plurality of CORESETs for the terminal device, and each CORESET may be separately associated with one first index value (for example, CORESETPoolIndex).),
wherein the CORESET comprises resources on which a physical downlink control channel (PDCCH) is transmitted from the network node (read as network device) (¶ [0082] One CORESET includes a plurality of physical resource blocks (PRBs). Transmission of a PDCCH is performed in the CORESET.; ¶ [0229] The network device sends the PDCCH to the terminal device.); and
deriving a spatial relation or a reference signal (RS) as pathloss (read as road loss) reference for said "codebook" or "nonCodebook" SRS resource or for said at least one SRS resource of the "codebook" or "nonCodebook" SRS resource set with reference to at least one reference signal (RS) from quasi-colocation (QCL) information of a CORESET associated with said control resource set pool index (¶ [0186] SRS for codebook-based uplink transmission (namely, an SRS in an SRS resource set whose usage parameter is codebook).; ¶ [0252] Each CORESET may be associated with a first index value, for example, CORESETPoolIndex.; ¶ [0290] The QCL reference signal resource of the typeD type in the TCI-state of the CORESET is used as the reference signal resource for road loss measurement for performing uplink transmission.),
when at least both of the following conditions are satisfied:
(1) when more than one value is configured for the control resource set pool index (¶ [0258] Each CORESET may be separately associated with one first index value (for example, CORESETPoolIndex). First index values associated with some CORESETs are 0, and first index values associated with some CORESETs are 1.), and
Fan does not explicitly teach wherein the QCL information comprises a relationship between one or more reference signals and demodulation reference signal (DMRS) port(s) of the PDCCH, transmitted on the CORESET and the relationship indicates channel parameter(s) or reception type parameter(s) that are obtained from the reference signals; when a higher-layer parameter is received from the network node that configures the UE to derive the spatial relation or the RS as pathloss reference for the SRS resource from the QCL information of the CORESET associated with the control resource set pool index.
In analogous art, Yu teaches wherein the QCL information comprises a relationship between one or more reference signals and demodulation reference signal (DMRS) port(s) of the PDCCH, transmitted on the CORESET and the relationship indicates channel parameter(s) or reception type parameter(s) that are obtained from the reference signals (¶ [0034], Table 1, QCL assumption is applied for the CORESET used for the transmission of Physical DL Control Channel (PDCCH). QCL parameter(s) used for the PDCCH QCL indication of the CORESET.; ¶ [0133] The “properties of the channel” may include Doppler shift, Doppler spread, average delay, delay spread, and spatial Reception (Rx) parameters. These properties may be categorized into different QCL parameters.; ¶ [0155] A TCI state may contain parameters for configuring a QCL relationship between one or two DL RSs and a target RS set. For example, a target RS set may be the DMRS ports of a PDCCH.).
Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to combine QCL information taught by Yu with SRS configuration and beam management taught by Fan. One would have been motivated to do so in order to increase efficiency and improve reliability by saving UL beam indication signaling for enabling spatial relation information based on the DL QCL assumption. (Yu: ¶¶ [0005-0008] & ¶ [0034]).
Fan and Yu do not explicitly teach when a higher-layer parameter is received from the network node that configures the UE to derive the spatial relation or the RS as pathloss reference for the SRS resource from the QCL information of the CORESET associated with the control resource set pool index
In analogous art, Vanugopal teaches when a higher-layer parameter is received from the network node that configures the UE to derive the spatial relation or the RS as pathloss reference for the SRS resource from the QCL information of the CORESET associated with the control resource set pool index (¶ [0053] If the UE is enabled to determine the default beam for the SRS (e.g., enableDefaultBeamPlForSRS), the UE may determine a RS resource index providing a RS resource with QCL-TypeD in the TCI state or the QCL assumption of a CORESET.).
Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to combine receiving a higher-layer parameter from the network as taught by Vanugopal with QCL information taught by Yu and SRS configuration and beam management taught by Fan. One would have been motivated to do so in order to improve the reliability and efficiency of SRS transmission by enabling the UE to use network configured QCL information to select an appropriate spatial relation or beam for the configured SRS resource, which would improve beam alignment and reduce unnecessary beam selection signaling and processing. (Vanugopal: ¶¶ [0003] & ¶ [0004]).
Regarding claim 26, Fan teaches wherein the higher layer configuration of an SRS resource comprises the higher layer parameter CORESETpoolIndex (¶ [0079] The resource may be an uplink signal resource. An uplink signal resource includes an SRS.; ¶ [0080] The resource is configured by using RRC signaling.; ¶ [0252] One SRS may be associated with one CORESET (for example, associated with one CORESET index). Each CORESET may be associated with a first index value, for example, CORESETPoolIndex.).
Regarding claim 32, Fan teaches transmitting, to the network node, said SRS according to the spatial relation with a reference to a RS associated with the QCL information of the CORESET having the lowest identification number (ID) (read as minimum index) among the CORESETs associated with said control resource set pool index (¶ [0212] The spatial relation may be determined based on the reference signal resource in the QCL corresponding to the CORESET with the minimum index.; ¶ [0251] The reference signal resource corresponding to the currently activated TCI-state of the control-resource set with the minimum index in the control-resource sets that are associated with the SRS is used to determine the spatial relation for transmission of the SRS.; ¶ [0252] One SRS may be associated with one CORESET. Each CORESET may be associated with a CORESETPoolIndex.).
Regarding claim 34, Fan teaches transmitting, to the network node (read as network device), an SRS using the derived spatial relation and/or pathloss (read as road loss) reference RS when more than one value is configured for the control resource set pool index (Fig. 1, illustrates a terminal device sending and receiving signals from a network device; ¶ [0056] Transmission performed by the terminal device in a direction of the network device may be referred to as uplink transmission.; ¶ [0180] A reference signal resource for road loss measurement that is used for the SRS.; ¶ [0185] Uplink transmission performed by the terminal device. The uplink transmission is uplink transmission of an SRS.; ¶ [0251] The reference signal resource of the control-resource set with the minimum index in the control-resource sets that are associated with the SRS used to determine the spatial relation for transmission of the SRS.; ¶ [0252] The first index value may be 0 or 1.; ¶ [0278] All CORESETs configured by the network device for the terminal device are associated with two different first index values (for example, CORESETPoolIndex). The network device needs to indicate an SRS spatial relation for uplink transmission.).
Regarding claim 35, Fan teaches a user equipment (UE) (read as terminal device) comprising a processor and a memory containing instructions executable by the processor (read as computer program code) (Fig. 5, element 50 terminal device, element 501 Processor, element 502 Memory containing computer program code; ¶ [0328] The memory is configured to store instructions.; ¶ [0342] The processor is configured to execute a computer program or instructions, to enable the communication device to implement the method on the terminal device. ¶ [0343] The terminal device may include memory and a processor.),
whereby said UE is operative to:
receive, from a network node (read as network device), a higher layer configuration (read as RRC) or a Medium Access Control-Control Element (MAC-CE) message that associates a sounding reference signal (SRS) resource or an SRS resource set comprising at least one SRS resource configured with a parameter usage that is set to "codebook" or "nonCodebook", with a control resource set pool index (¶ [0079] The resource may be an SRS.; ¶ [0080] The resource is configured by using RRC signaling.; ¶ [0186] An SRS for codebook-based uplink transmission (an SRS in an SRS resource set whose usage parameter is codebook).; ¶ [0191] The spatial relation that is delivered by the network device may be carried in downlink signaling, such as RRC signaling or media access control element (MAC-CE) signaling.; ¶ [0252] One SRS may be associated with one CORESET. Each CORESET may be associated with a CORESETPoolIndex.),
wherein the control resource set pool index is a higher-layer parameter in a configuration of a control resource set (CORESET) (¶ [0141] The CORESET may be configured by using a control-resource set parameter in RRC signaling.; ¶ [0258] The network device may configure a plurality of CORESETs for the terminal device, and each CORESET may be separately associated with one first index value (for example, CORESETPoolIndex).),
wherein the CORESET comprises resources on which a physical downlink control channel (PDCCH) is transmitted from the network node (read as network device) (¶ [0082] One CORESET includes a plurality of physical resource blocks (PRBs). Transmission of a PDCCH is performed in the CORESET.; ¶ [0229] The network device sends the PDCCH to the terminal device.); and
derive a spatial relation or a reference signal (RS) as pathloss (read as road loss) reference for said "codebook" or "nonCodebook" SRS resource or for said at least one SRS resource of the "codebook" or "nonCodebook" SRS resource set with reference to at least one reference signal (RS) from quasi-colocation (QCL) information of a CORESET associated with said control resource set pool index (¶ [0186] SRS for codebook-based uplink transmission (namely, an SRS in an SRS resource set whose usage parameter is codebook).; ¶ [0252] Each CORESET may be associated with a first index value, for example, CORESETPoolIndex.; ¶ [0290] The QCL reference signal resource of the typeD type in the TCI-state of the CORESET is used as the reference signal resource for road loss measurement for performing uplink transmission.),
when at least both of the following conditions are satisfied:
(1) when more than one value is configured for the control resource set pool index (¶ [0258] Each CORESET may be separately associated with one first index value (for example, CORESETPoolIndex). First index values associated with some CORESETs are 0, and first index values associated with some CORESETs are 1.), and
Fan does not explicitly teach wherein the QCL information comprises a relationship between one or more reference signals and demodulation reference signal (DMRS) port(s) of the PDCCH, transmitted on the CORESET and the relationship indicates channel parameter(s) or reception type parameter(s) that are obtained from the reference signals; when a higher-layer parameter is received from the network node that configures the UE to derive the spatial relation or the RS as pathloss reference for the SRS resource from the QCL information of the CORESET associated with the control resource set pool index.
In analogous art, Yu teaches wherein the QCL information comprises a relationship between one or more reference signals and demodulation reference signal (DMRS) port(s) of the PDCCH, transmitted on the CORESET and the relationship indicates channel parameter(s) or reception type parameter(s) that are obtained from the reference signals (¶ [0034], Table 1, QCL assumption is applied for the CORESET used for the transmission of Physical DL Control Channel (PDCCH). QCL parameter(s) used for the PDCCH QCL indication of the CORESET.; ¶ [0133] The “properties of the channel” may include Doppler shift, Doppler spread, average delay, delay spread, and spatial Reception (Rx) parameters. These properties may be categorized into different QCL parameters.; ¶ [0155] A TCI state may contain parameters for configuring a QCL relationship between one or two DL RSs and a target RS set. For example, a target RS set may be the DMRS ports of a PDCCH.).
Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to combine QCL information taught by Yu with SRS configuration and beam management taught by Fan. One would have been motivated to do so in order to increase efficiency and improve reliability by saving UL beam indication signaling for enabling spatial relation information based on the DL QCL assumption. (Yu: ¶¶ [0005-0008] & ¶ [0034]).

Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to combine receiving a higher-layer parameter from the network as taught by Vanugopal with QCL information taught by Yu and SRS configuration and beam management taught by Fan. One would have been motivated to do so in order to improve the reliability and efficiency of SRS transmission by enabling the UE to use network configured QCL information to select an appropriate spatial relation or beam for the configured SRS resource, which would improve beam alignment and reduce unnecessary beam selection signaling and processing. (Vanugopal: ¶¶ [0003] & ¶ [0004]).
Claim 27 is rejected under 35 U.S.C. 103 as being unpatentable over Fan in view of Yu further in view of Venugopal and Kim et al. (US 2022/0287054 A1; hereinafter Kim).
Regarding claim 27, Fan, Yu, and Vanugopal do not explicitly teach wherein the higher layer configuration is an information element (IE), comprising a list of at least one SRS resource or at least one SRS resource set and further comprising said control resource set pool index.
In analogous art, Kim teaches wherein the higher layer configuration is an information element (IE) (read as SRS resource indicator field and ControlResourceSet information element (IE)), comprising a list of at least one SRS resource or at least one SRS resource set and further comprising said control resource set pool index (¶ [0172] Configured SRS resources in an SRS resource set associated with higher layer parameter may be indicated by an SRS resource indicator field. ¶ [0214] ControlResourceSet information element (IE) that is a higher layer parameter is used to configure a CORESET. The ControlResourceSet IE may include an index of a CORESET pool for CORESET (e.g., CORESETPoolIndex).
Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to combine an information element (IE) comprising an SRS resource or SRS resource set and control resource set pool index as taught by Kim with receiving a higher-layer parameter from the network as taught by Vanugopal, QCL information taught by Yu, and an SRS configuration and beam management taught by Fan. One would have been motivated to do so in order to reduce power consumption, improve efficient use of spectrum, and increase reliability by allowing the UE to derive its SRS transmit beam, path-loss estimate and power settings from one higher layer message without extra configuration steps. (Kim: ¶ [0081], ¶¶ [0169-0174], and ¶¶ [0213-0214]).
Allowable Subject Matter
