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.
Claim(s) 1-2, 7, 12-14, 19, 24-28, and 30 is/are rejected under 35 U.S.C. 103 as being unpatentable over Guan et al. (hereinafter “Guan”, US 2025/0212227) in view of Liu et al. (hereinafter “Liu ‘158”, US 2022/0038158).
Regarding claims 1 and 26, Guan discloses an apparatus for wireless communication at a user equipment (UE), and a method for wireless communications by a user equipment (UE) (i.e., a terminal device 1400 as described in paragraph 0313), comprising:
at least one memory comprising computer-executable instructions (i.e., memory 1420 stores program 1430 as described in paragraphs 0314-0315); and
one or more processors configured to execute the computer-executable instructions (i.e., processor 1410 as described in paragraphs 0314-0315) and cause the UE to:
receive, from the network entity, signaling scheduling the UE for simultaneous transmission of at least one PUSCH using uplink ports shared across multiple panels of the UE (i.e., UE receives DCI for scheduling an uplink transmission and performing simultaneous transmission across multi-panels as described in paragraph 0173, and in Abstract), wherein the signaling indicates a first set of PUSCH ports corresponding to a subset of SRS ports associated with SRS resources in the first SRS resource set and a second set of PUSCH ports corresponding to a subset of SRS ports associated with SRS resources in the second SRS resource set (i.e., UE determines a first/second set of antenna port (PUSCH port) indexes associated with the first panel 125-1 and second panel 125-2. UE transmits PUSCH using the same antenna ports as the SRS ports in the SRS resources indicated by both indicators as described in paragraphs 174-0177); and
transmit the at least one PUSCH via a first panel of the UE using the first set of PUSCH ports and via a second panel of the UE using the second set of PUSCH ports (i.e., UE transmits PUSCH using the antenna ports as the SRS ports in the SRS resources indicated by both SRS resource indicators as described in paragraphs 0177-0179).
Guan, however, does not expressly disclose:
receive, from a network entity, a configuration of at least first and second sounding reference signal (SRS) resource sets for codebook-based physical uplink shared channel (PUSCH) transmissions.
In a similar endeavor, Liu ‘158 discloses method and apparatus for multiple panel and/or multiple beam codebook based PUSCH transmissions. Liu ‘158 also discloses:
receive, from a network entity, a configuration of at least first and second sounding reference signal (SRS) resource sets for codebook-based physical uplink shared channel (PUSCH) transmissions (i.e., UE receives two or more sounding reference signal resources that are used for the codebook based physical uplink shared channel transmission as described in Abstract, and in paragraph 0007).
Therefore, it would have been obvious to one of ordinary skilled in the art to modify the teachings of the cited references, and arrive at the present invention.
The motivation/suggestion for doing so would have been to enable efficient beamforming and improve system performance in MIMO systems.
Regarding claims 2, 14, and 27, Guan and Liu ‘158 disclose all limitations recited within claims as described above. Liu ‘158 also discloses wherein receiving the signaling comprises receiving downlink control information (DCI) with a field that indicates a transmitted precoding matrix indicator (TPMI) index associated with at least one of the first SRS resource set or the second SRS resource set (i.e., the DCI received by the UE includes TPMI as described in paragraph 0002 and Abstract).
Regarding claims 7, 19, and 28, Guan and Liu ‘158 disclose all limitations recited within claims as described above. Guan also discloses wherein the one or more processors are further configured to cause the UE to determine uplink ports are shared across multiple panels of the UE based on at least one of:
the UE transmitting signaling indicating a capability of the UE to support uplink ports shared across multiple panels of the UE (i.e., UE capability as described in paragraphs 0088-0090, and 0114-0115);

a configured maximum rank parameter for single PUSCH transmission being larger than a configured maximum rank parameter for simultaneous PUSCH transmission on multiple panels.
Regarding claims 12 and 25, Guan and Liu ‘158 disclose all limitations recited within claims as described above. Liu ‘158 also discloses wherein the one or more processors are further configured to cause the UE to determine when the signaling indicates the first set of PUSCH ports corresponding to the subset of SRS ports associated with the first SRS resource set and the second set of PUSCH ports corresponding to the subset of SRS ports associated with the second SRS resource set based on at least one of:
capability signaling by the UE;
a radio resource control (RRC) signaling;
a codebook subset configuration; or
an indication in a downlink control information (DCI) (i.e., based on the DCI as described in Abstract).
Regarding claim 24, Guan and Liu ‘158 disclose all limitations recited within claims as described above. Guan also discloses wherein the one or more processors are further configured to cause the network entity to determine when the signaling indicates the first set of PUSCH ports corresponding to the subset of SRS ports associated with the first SRS resource set and the second set of PUSCH ports corresponding to the subset of SRS ports associated with the second SRS resource set based on UE capability signaling (i.e., based on the capability of a terminal device as described in paragraph 0052).
Regarding claims 13 and 30, Guan discloses an apparatus for wireless communications at a network entity, and a method for wireless communications by a network entity (i.e., network devices 1400 as described in paragraph 0313), comprising:
at least one memory comprising computer-executable instructions (i.e., memory 1420 stores program 1430 as described in paragraphs 0314-0315); and
