Office Action

§103 §112
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 . This office action is in response to remarks filed 12/01/2025. Claims 1-20 are pending and presented for examination. Claims 1-12 are amended. Claims 13-20 are added. No claims are deleted. Continued Examination Under 37 CFR 1.114 A request for continued examination under 37 CFR 1.114, including the fee set forth in 37 CFR 1.17(e), was filed in this application after final rejection. Since this application is eligible for continued examination under 37 CFR 1.114, and the fee set forth in 37 CFR 1.17(e) has been timely paid, the finality of the previous Office action has been withdrawn pursuant to 37 CFR 1.114. Applicant's submission filed on 12/01/2025 has been entered. Claim Rejections - 35 USC § 112 The following is a quotation of the first paragraph of 35 U.S.C. 112(a): (a) IN GENERAL.—The specification shall contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same, and shall set forth the best mode contemplated by the inventor or joint inventor of carrying out the invention. The following is a quotation of the first paragraph of pre-AIA 35 U.S.C. 112: The specification shall contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same, and shall set forth the best mode contemplated by the inventor of carrying out his invention. Claims 1, 5, 6, and 10 are rejected under 35 U.S.C. 112(a) or 35 U.S.C. 112 (pre-AIA ), first paragraph, as failing to comply with the written description requirement. The claim(s) contains subject matter which was not described in the specification in such a way as to reasonably convey to one skilled in the relevant art that the inventor or a joint inventor, or for applications subject to pre-AIA 35 U.S.C. 112, the inventor(s), at the time the application was filed, had possession of the claimed invention. Claims 1, 5, 6, and 10 amended limitation recites a FFP-UCI resource or transmission “at or within a predetermined number of symbols from a start of the WTRU-specific FFP on at least one of a … a physical random access channel (PRACH),” The specification does not disclose a PRACH transmission from a start of the WTRU-specific FFP with one or more resources or a predetermined number of symbols, ¶¶0080, 0081, 0124, 0129. 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 1-13, 16, 17, and 20 are rejected under 35 U.S.C. 103 as being unpatentable over Singh et al. (US 20230189338 A1, hereinafter “Singh”), in view of Li et al.

Claims 14 and 18 are rejected under 35 U.S.C. 103 as being unpatentable over Singh, in view of Li, in view of Moon ‘275, in view of Moon et al. (US 20200280971 A1, hereinafter “Moon ‘971”). RE Claim 14, 18, Singh, Li, and Moon ‘275 do not explicitly disclose a method or apparatus: wherein the FFP-UCI includes a bitmap identifying LBT sub-bands acquired by the WTRU for the WTRU-initiated COT. However, Moon ‘971 discloses: wherein the FFP-UCI includes a bitmap identifying LBT sub-bands acquired by the WTRU for the WTRU-initiated COT (In frame based equipment operation, a communication node, terminal, performs CCA at a starting time of each fixed frame period. ¶¶0132-0133; Terminal initiates COT by performing CCA operation. ¶0127, Fig. 4B; In order to determine whether the LBT subband is occupied, the terminal may apply an operation (e.g., bit (or bitwise) operation) according to a predefined rule to bit(s) corresponding to the LBT subband(s) obtained from one or more bitmaps, and determine whether the LBT subband is occupied based on a result of the operation. ¶0262; When one bandwidth part includes a plurality of LBT subbands, the base station may obtain starting time point information, transmission bandwidth information, etc. of an uplink transmission burst from the terminal. The starting time point information and the transmission bandwidth information of the uplink transmission burst may be transmitted from the terminal to the base station through uplink control information (UCI). ¶0264).

(US 20220174741 A1, hereinafter “Myung”). RE Claim 15, 19, Singh, Li, and Moon ‘275 do not explicitly disclose a method or apparatus: wherein the FFP-UCI indicates at least one of: (i) an energy-detection threshold used for clear channel assessment or (ii) spatial beam parameters used to perform the assessment. However, Myung discloses: wherein the FFP-UCI indicates at least one of: (i) an energy-detection threshold used for clear channel assessment (Method in which the UE selects an ED threshold to be used for LBT performed before transmitting a CG-PUSCH as follows and indicates the selected ED threshold through CG-UCI, upon receiving a first ED threshold to be used to perform UL LBT for UL-to-DL COT sharing from the BS by higher-layer signaling such as RRC signaling. ¶0234) or (ii) spatial beam parameters used to perform the assessment (UCI includes CSI feedback and MIMO related feedback information including RI and PMI. ¶0081). It would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to combine the teachings of Singh, determination of resources in a FFP that overlap during a COT, with the teachings of Li, determine a priority for initiation of a COT based on priority of LBT or priority of data, with the teachings of Moon ‘275, determination of a transmission resource for a UCI based on validity, availability, of resources combined with a symbol offset to transmit a UCI over PUSCH or PUCCH, with the teachings of Myung, terminal provides energy detection threshold used for CCA to the base station for configured or dynamic grant PUSCH.
