Office Action

§103 §112
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 . DETAILED ACTION Claims 1 – 20 are presented for examination. Priority Applicant’s claim for the benefit of a prior-filed application under 35 U.S.C. 120 and under 35 U.S.C. 365(c) is acknowledged. Information Disclosure Statement The information disclosure statement (IDS) submitted on 01/27/2025 was received. The submission is in compliance with the provisions of 37 CFR 1.97. Accordingly, the information disclosure statement is being considered by the examiner. Specification The abstract of the disclosure is objected to because the language “The subject disclosure relates to a method and apparatus for reducing a one-shot HARQ-ACK codebook size” is a purported merit and fails to provide a concise statement of the technical disclosure of the patent. Applicant is reminded of the proper content of an abstract of the disclosure. A patent abstract is a concise statement of the technical disclosure of the patent and should include that which is new in the art to which the invention pertains. The abstract should not refer to purported merits or speculative applications of the invention and should not compare the invention with the prior art. The abstract should be in narrative form and generally limited to a single paragraph on a separate sheet within the range of 50 to 150 words in length. The abstract should describe the disclosure sufficiently to assist readers in deciding whether there is a need for consulting the full patent text for details. The language should be clear and concise and should not repeat information given in the title. It should avoid using phrases which can be implied, such as, “The disclosure concerns,” “The disclosure defined by this invention,” “The disclosure describes,” etc. In addition, the form and legal phraseology often used in patent claims, such as “means” and “said,” should be avoided. A corrected abstract of the disclosure is required and must be presented on a separate sheet, apart from any other text. See MPEP § 608.01(b). Claim Rejections - 35 USC § 112 The following is a quotation of 35 U.S.C. 112(b): (b) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention. The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph: The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention. Claims 1 – 20 are rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention. Claim 1 recites the limitation "the PUCCH". There is insufficient antecedent basis for this limitation in the claim. Claim 11 recites the limitation "the PUCCH". There is insufficient antecedent basis for this limitation in the claim. Claim 19 recites the limitation "the PUCCH". There is insufficient antecedent basis for this limitation in the claim. Claim 20 recites the limitation "the PUCCH". There is insufficient antecedent basis for this limitation in the claim. Any claim not addressed above is rejected due to its dependency on a rejected claim 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. Claims 1 – 18 and 20 are rejected under 35 U.S.C. 103 as being unpatentable over Wang et al., U.S. Publication 2020/0358587 (herein Wang I), in view of Wang et al., U.S. Publication 2019/0103943 (herein Wang II). Regarding claim 1, Wang I teaches: A user equipment (UE) for wireless communication, comprising: at least one memory; and at least one processor coupled with the at least one memory (paragraph 0147) and configured to cause the UE to: receive a first signaling configuring a plurality of carriers, wherein hybrid automatic repeat request-acknowledgement (HARQ-ACK) feedback for the plurality of carriers is transmitted in same physical uplink control channel (PUCCH) (figure 3; 13, element ST102; paragraph 0041, 0042, 0134); receive downlink control information (DCI) requesting HARQ-ACK feedback for one or more carriers of the plurality of carriers (figure 3, paragraph 0041, 0042), the DCI including a bitmap identifying one or more HARQ-ACK processes (paragraph 0028, 0120); transmit the HARQ-ACK codebook in the PUCCH (figure 3; paragraph 0041 – 0043).
