Office Action

§102 §103
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 . Claim Objections Claims 1, 3-5, 7, 9-10, 12-14, 16, 18 are objected to because of the following reasons: From the claim language, Examiner assumes that it is the one or more processors that perform the functional steps. However, Examiner recommends Applicants to further clarify the claim language by changing the phrase “to cause the apparatus to” to “to cause the one or more processors to”. Otherwise, if Applicants intends for some other hardware components of the apparatus to perform the steps, then please amend the claims to include those hardware components and clearly indicate that those hardware components perform the steps. If Applicants intends for any unknown hardware components of the apparatus to perform the steps, then please clearly states so on record. However, Applicants are reminded that doing so will raise 112 issues since then the claim language would impose no limits as to a particular structure for performing the claimed invention; hence the claims may cover all devices for/ways for performing the claimed functions. As thus, there is a failure to provide a clear-cut indication of claim scope because the functional language is not sufficiently precise and definite, resulting in no boundaries on the claim limitation. Appropriate correction is required. Claim Rejections - 35 USC § 102 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 – (a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale or otherwise available to the public before the effective filing date of the claimed invention. (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.

(Zhang, paragraph 147-149, based on the indication, UE reports at least one of power headroom report for full duplex or power headroom report for half duplex to network entity) 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 of this title, 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 set forth in Graham v. John Deere Co., 383 U.S. 1, 148 USPQ 459 (1966), that are applied 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. Claims 9, 18 are rejected under 35 U.S.C. 103 as being unpatentable over Zhang, US 20220110072 in view of Su, US 20220159580. For claim 9. Zhang discloses all the limitations of claim 1, however Zhang doesn’t teach: wherein the one or more processors are configured to cause the apparatus to send capability information that indicates the apparatus supports reporting power headroom information associated with full-duplex communications. Su from the same or similar fields of endeavor teaches: wherein the one or more processors are configured to cause the apparatus to send capability information that indicates the apparatus supports reporting power headroom information associated with full-duplex communications. (Su, fig 15, paragraph 209, 217, terminal sends capability information indicating whether the terminal supports full duplex, when the base station receives the capability information that the terminal reports and the reported capability information includes the information indicating that the terminal supports the full duplex, base station transmits an indication to the terminal so as to indicate that the terminal may report the full duplex mode power headroom) Thus it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to implement the teachings of Su into Zhang, since Zhang suggests a technique for network entity (base station) communicating an indication to UE (terminal) informing the UE to report power headroom report for full duplex, and Su suggests the beneficial way of including into such technique receiving capability information indicating whether the terminal supports full duplex and communicating such indication when the capability information includes the information indicating that the terminal supports the full duplex (Su, fig 15, paragraph 209, 217) to ensure that the terminal can supports power headroom reporting for full duplex thus improve communication efficiency in the analogous art of communication. For claim 18. Zhang discloses all the limitations of claim 10, however Zhang doesn’t teach: wherein the one or more processors are configured to cause the apparatus to obtain capability information that indicates a user equipment supports reporting power headroom information associated with full-duplex communications. Su from the same or similar fields of endeavor teaches: wherein the one or more processors are configured to cause the apparatus to obtain capability information that indicates a user equipment supports reporting power headroom information associated with full-duplex communications. (Su, fig 15, paragraph 209, 217, terminal sends capability information indicating whether the terminal supports full duplex, when the base station receives the capability information that the terminal reports, and the reported capability information includes the information indicating that the terminal supports the full duplex, base station transmits an indication to the terminal so as to indicate that the terminal may report the full duplex mode power headroom) Thus it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to implement the teachings of Su into Zhang, since Zhang suggests a technique for network entity (base station) communicating an indication to UE (terminal) informing the UE to report power headroom report for full duplex, and Su suggests the beneficial way of including into such technique receiving capability information indicating whether the terminal supports full duplex and communicating such indication when the capability information includes the information indicating that the terminal supports the full duplex (Su, fig 15, paragraph 209, 217) to ensure that the terminal can supports power headroom reporting for full duplex thus improve communication efficiency in the analogous art of communication.
