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 . Claims 1-20 are pending.
Claim Objections
Claims 1-6, 8-17, 19-20 are objected to because of the following informalities: The instant claims do not define the various acronyms such as “RNTI”, “CORESET”, “RRC”, “HARQ”, “RV”, “PDCCH”, “TCI”, “QCL”, and “PCI”.
Appropriate correction is required.
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.
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, 7, 12, 18-19 are rejected under 35 U.S.C. 103 as being unpatentable over Bae et al. (US# 2024/0073887 hereinafter referred to as Bae) in view of Zhang et al. (US# 2022/0369300 hereinafter referred to as Zhang).
RE Claim 1, Bae discloses a first node for wireless communications, comprising:
a first receiver, receiving a first signaling, the first signaling indicating scheduling activation (See Bae [0170]-[0171] – receiving signaling indicating scheduling activation (e.g. DL SPS, UL grant type 2 activation)), the first signaling being identified by a first RNTI, the first RNTI being an RNTI of first type (See Bae [0170]-[0171] – i.e. scrambled with the CS-RNTI); and

The fourth configuration information sent by the first network device to the terminal device may be further used to configure the timer corresponding to the third configuration information, so that the terminal device can determine whether the first configuration information is valid, thereby preventing the terminal device from performing invalid data transmission).
RE Claim 12, Bae discloses a second node for wireless communications, comprising:

For example, a wireless device capability (e.g., DL/UL switching time, BWP switching time, DL preparation time, and/or measurement gap) may indicate a second time offset “1” to determine the earliest CORESET/search space set, and/or the semi-statically configured CORESET/search space set of the target cell).
