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 . Specification The lengthy specification has not been checked to the extent necessary to determine the presence of all possible minor errors. Applicant’s cooperation is requested in correcting any errors of which applicant may become aware in the specification. 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 21-22 and 29-30 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 21, line 2, “the second CCS” lacks of proper antecedent basis. It appears that “the second CCA” was intended. Claim 22, line 2, “the CCS view length” lacks of proper antecedent basis. It appears that “the CCS view length” was intended. Claim 29, line 2, “the second CCS” lacks of proper antecedent basis. It appears that “the second CCA” was intended. Claim 30, line 2, “the CCS view length” lacks of proper antecedent basis. It appears that “the CCS view length” was intended. Allowable Subject Matter Claims 17-20, 23-28 and 31-32 are allowed. Claims 21-22 and 29-30 would be allowable if rewritten or amended to overcome the rejection(s) under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), 2nd paragraph, set forth in this Office action. The following is a statement of reasons for the indication of allowable subject matter: a wireless transmit/receive unit (WTRU) and method are disclosed. The closest prior art Su, US2023/0171066 A1, recites a method and apparatus comprising (fig. 2) receiving configuration information from a remote network (S203); determining transmission resource based on the configuration information(S204). However, it fails to teach or fairly suggest, in combination with the other claimed limitations, the limitations of” receive canonical correlation analysis (CCA) configuration information; determine, based on the CCA configuration information, a first CCA view and a second CCA view, wherein the first CCA view and the second CCA view are associated with a data channel; measure a CCA correlation coefficient associated with the first CCA view and the second CCA view; determine CCA sub-grid information based at least on the first CCA view, the second CCA view, and the CCA correlation coefficient, wherein the determined CCA sub-grid information comprises a determined sub-grid size, a determined number of sub-grids, and a determined number of CCA reference signals (CCA-RSs);determine whether to send an indication of the determined sub-grid size based on whether the determined sub-grid size is equal to a configured sub-band size; and send a report based on the determination of whether to send the indication of the determined sub-grid size, wherein the report indicates the determined number of CCA-RSs and the CCA correlation coefficient”, recited in the base claim(s). Conclusion Any inquiry concerning this communication or earlier communications from the examiner should be directed to JEAN B CORRIELUS whose telephone number is (571)272-3020. The examiner can normally be reached 10:00AM-3:00PM Monday-Thursday.
