§103
DETAILED ACTION Claims 1-11 and 16-25 are presented for examination. Claims 12-15 and 26-30 are canceled. Claims 1, 11, and 16 are amended. 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 Arguments Applicant’s arguments with respect to claim(s) 1 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. Claim(s) 1-11 and 16-25 is/are rejected under 35 U.S.C. 103 as being unpatentable over Park et al., (hereinafter Park), U.S. Publication No. 2020/0083939, in view of Harrison et al., (hereinafter Harrison), U.S. Publication No. 2021/0359733.

Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. Yang et al., U.S. Publication No. 2024/0187072 discloses maintaining coherence between multiple transmission antennas for a carrier with two uplink transmission antennas when dynamical switching between two frequency bands is performed. Huang et al., U.S. Publication No. 2019/0393931 discloses wherein coherence can be maintained between antenna ports.
