Office Action

§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 . 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and the fee set forth in 37 CFR 1.17(e) has been timely paid, the finality of the previous Office action has been withdrawn pursuant to 37 CFR 1.114.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 02/16/2026 has been entered. Response to Arguments Applicant’s arguments, filed 2/16/2026 for the new amendments, with respect to the combination of prior arts have been fully considered and are persuasive. The rejection of the claims using the combination of previous prior arts has been withdrawn. 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. Claim 1-20 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. Regarding claims 1, 8 and 15, recites the limitation “…determine whether power saving is desired; In response to determining that power savings is desired, executing an extended Antenna-Carrier Identifier (eAxC-ID) based traffic shaping method…”. The portion of the disclosure of the instant application that recites power saving is indicated below: [0087] In operation 824, a determination is made whether power savings is needed or desirable. In some embodiments, if power savings is needed or desirable, operation 826 is executed. In some embodiments, if power savings is not needed or desirable, operation 822 is executed. However, from the above paragraph: 1/ it is not clear how a determination is made of whether power saving is desired or not. The claims just mention determine if power saving is desired where it does not give a PHOSITA what determination steps or processes insure power saving is desired to know when power saving is desired. For instance, is it active monitoring; threshold implementation; traffic condition monitoring; link load condition measuring that indicates a determination that power saving is desired to mitigate power usage issue? In a current claim, determine if power saving is desired, is a mere statement without indicating in the disclosure how that determination is made. Therefore, limits and bounds of the claims are indeterminate for a PHOSITA to know the scope of the claims in light of the above paragraph, hence rendering the claims indefinite. 2/ Further, for the limitation: In response to determining that power savings is desired, executing an extended Antenna-Carrier Identifier (eAxC-ID) based traffic shaping method, the disclosure does not indicate what correlation exists between power saving and eAxC-ID scheduling? From the disclosure, it is not clear how the need for power saving leads to eAxc-ID scheduling for power saving management. For instance, it is not clear from the disclosure how using eAxc-ID based scheduling indicated in the disclosure and fig. 2 that is using a specific range of eAxc-IDs for specific portion of traffic separately such as: the first portion of fronthaul traffic and the second portion of fronthaul traffic associated with respective range of eAxc-IDs helps in power saving. Therefore, it is not clear from the disclosure how the above parameters are related to know the limits and bounds of the above limitations, hence rendering the claims indefinite. Regarding claims 2, 9, and 16, The claim recites “ total number N of eAxc-IDs, the first range comprises eAxC-IDs from 1 to N/2-1; and the second range comprises eAxc-IDS from N/2 to N-1” -This range is not clear. If we assume N is an odd number, N/2 is not a whole number or integer and it is not clear how a number that is not integer can be used for indexing a count. Examiner suggests using language in line of the following: first range =1 to M; second range= M+1 to N-1, where M <N.
