§103
DETAILED ACTION Notice of Pre-AIA or AIA Status The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . Response to Amendment Amendments filed on 10/22/2025 are entered. The amendments change the scopes of the previously presented claims. New grounds of rejections are applied to the amended claims and the current Office Action is made FINAL as necessitated by the claim amendments. Response to Arguments Applicant’s arguments with respect to claim(s) 1, 4-11 and 14-20 have been considered but are moot because the new ground of rejection does not rely on any reference applied in the prior rejection of record for any teaching or matter specifically challenged in the argument. 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. Claim(s) 1, 4-8, 10-11, 14-18 and 20-24 is/are rejected under 35 U.S.C. 103 as being unpatentable over Guo ‘512 (US 2025/0024512 A1) in view of Go (US 2025/0151063) and Fan (US 2024/0205855).

Fan discloses the following features. Regarding claims 1 and 11, a TAG parameter used to determine a TAG (see “the SSB group is sent to the terminal by using an RRC configuration message… the association relationship between the SSB group and the TAG is sent to the terminal by using the RRC configuration message” recited in paragraph [0195]), of the first TAG and the second TAG, for applying a TAC comprised in the RAR (see “The terminal determines, based on the SSB corresponding to the RAR message, the TAG corresponding to the initial TA value indicated in the RAR message” recited in paragraph [0195]; and paragraph [0193] shows that the RAR includes a timing advance command); applying the TAC to the TAG wherein the TAG is the first TAG based on the TAG parameter; and the second TAG based on the TAG parameter (see “a TAG corresponding to an initial TA value indicated by the timing advance command field in the RAR message is determined by using an SSB corresponding to the RAR message” recited in paragraph [0194] and see “The terminal determines, based on the SSB corresponding to the RAR message, the TAG corresponding to the initial TA value indicated in the RAR message” recited in paragraph [0195]). It would have been obvious to one of ordinary skill in the art at the effective filing date of the current application to modify the system of Guo ‘512 using features, as taught by Go and Fan, in order to configure uplink transmission operation of a terminal for a serving cell serving multiple timing advance groups (see paragraphs [0201]-[0203] of Go) and in order to reduce the transmission overhead in a RAR message (see paragraph [0194] of Fan). Claim(s) 9 and 19 is/are rejected under 35 U.S.C. 103 as being unpatentable over Guo ‘512, Go and Fan as applied to claims 1-2 and 11-12 above, and further in view of Comsa (US 2024/0188015 A1). Guo ‘512, Go and Fan disclose the features as shown above. Guo ‘512 does not disclose the following features: regarding claims 9 and 19, wherein transmitting the uplink signal with a transmit power that is determined based on the uplink TCI state. Comsa discloses the following features. Regarding claims 9 and 19, wherein transmitting the uplink signal with a transmit power that is determined based on the uplink TCI state (see “The WTRU may further set the power of this PUCCH based on the first or second set of power control parameters for PUCCH configured for the identified enhanced TCI state” recited in paragraph [0190]). It would have been obvious to one of ordinary skill in the art at the effective filing date of the current application to modify the system of Guo ‘512, Go and Fan using features, as taught by Comsa, in order to allow a WTRU to communicate with multiple TRPs simultaneously (see paragraph [0090] of Comsa).
