Also, on line 2, the term “SP field” should be recited “special (SP) field” in this first instance. Regarding claim 6 , on line 5, the term “SSB” should be recited “synchronization signal block (SSB)” in this first instance. Also, on line 5, the term “CSI-RS” should be recited “channel state information reference signal (CSI-RS)” in this first instance. Claims 5-9 are also objected to as being dependent on claim 4 and containing the same deficiency.

Claim Rejections - 35 USC § 102 07-06 AIA 15-10-15 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. 07-07-aia AIA 07-07 The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action: A person shall be entitled to a patent unless – 07-12-aia AIA (a)(2) the claimed invention was described in a patent issued under section 151, or in an application for patent published or deemed published under section 122(b), in which the patent or application, as the case may be, names another inventor and was effectively filed before the effective filing date of the claimed invention. 07-15-03-aia AIA Claim(s) 1-10 and 12-18 is/are rejected under 35 U.S.C. 102(a)(2) as being anticipated by Koskela et al.

Claim Rejections - 35 USC § 103 07-06 AIA 15-10-15 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. 07-20-aia AIA 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. 07-20-02-aia AIA 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. 07-21-aia AIA Claim (s) 11 is/are rejected under 35 U.S.C. 103 as being unpatentable over Koskela in view of Karimidehkordi et al. (U.S. 2023/0084028) (hereinafter “Karimidehkordi”) . Regarding claim 11 , Koskela teaches claim 10 as described above. Koskela does not explicitly teach “a value of the LCID is any of values 35-44”. However, Karimidehkordi teaches a method and system for beam failure recovery where codepoint/index values of 35-44 are reserved values for LCID as shown in TABLE 5 on page 11. Given the above references, it would have been obvious to someone of ordinary skill in the art, before the effective filing date of the invention, to apply the LCID values taught in Karimidehkordi to the BFR system of Koskela in order to ensure successful forming of a bitmap for beam failure recovery by utilizing reserved values of LCID for UL-SCH, thereby improving the reliability of the failure recovery process as spoken of on page 11, paragraphs [0110]-[0111] of Karimidehkordi . Conclusion 07-96 AIA The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. References considered relevant to this application are listed in the attached “Notice of References Cited” (PTO-892) .
