Response to Arguments
Applicant’s arguments with respect to claim(s) 1,4-6,9,11-13,15, and 20-24 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
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 (i.e., changing from AIA to pre-AIA ) 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.
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.
The factual inquiries for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows:
1. Determining the scope and contents of the prior art.
2. Ascertaining the differences between the prior art and the claims at issue.
3. Resolving the level of ordinary skill in the pertinent art.
4. Considering objective evidence present in the application indicating obviousness or nonobviousness.
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 1,4-6,11,12,15, and 20-24 are rejected under 35 U.S.C. 103 as being unpatentable over as Yue et al, US 20230284214 A1, in view of Wei et al, US 20220095359 A1.

wherein selecting the first transport block from the plurality of transport blocks to transmit on the time-frequency resource comprises: when there are a first plurality of transport blocks with the highest logical channel priority among the plurality of transport blocks, selecting one transport block from the first plurality of transport blocks with the highest logical channel priority as the first transport block according to the following rule([0040] [0061] The uplink grant may indicate some specific radio resources (e.g., time and/or frequency resources)for the UE 101 to perform uplink transmission. Then, if following the rule of NR-U and if the Transport Block Size (TBS) configured by the grant CG1 is the same as the TBS of the packet data unit PDU3, the configured grant CG1 is pre-empted by there transmission of the packet data unit PDU3 although the priority of the logical channelLCH3 is lower than that of the logical channelLCH1The logical channel enters the urgent state is determined as the highest priority among the logical channels with equal priority or logical channels that the difference value of the priorities is less than a threshold.):
selecting, from the first plurality of transport blocks with the highest logical channel priority, a transport block to be retransmitted as the first transport blocks([0052] if the retransmission can be transmitted on the uplink grant and the highest priority among priorities of the logical channels multiplexed in the retransmission MACPDU is higher than the highest priority among priorities of the logical channels with data available that are multiplexed or can be multiplexed in an initial transmission MACPDU to be transmitted on the uplink grant, the priority of the uplink grant is determined by the highest priority among priorities of the logical channels with data available that are multiplexed in the retransmitted MAC PDU.).
