Office Action

§102
DETAILED ACTION This Final Office Action is in response to application number 18,020,179 filed on February 7th, 2023. The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . Priority Acknowledgment is made of applicant’s claim for foreign priority under 35 U.S.C. 119 (a)-(d). The certified copy has been filed on February 7th, 2023. 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. Claims 1,12 and 25 are rejected under 35 U.S.C. 102(a)(2) as being anticipated by Xu (EP 4102911 A1). Regarding claims 1,12 and 25, Wei et al. disclose a method for determining a control-channel-element (CCE) index, comprising: determining a CCE index of a physical downlink control channel (PDCCH) candidate according to a number of CCEs in a plurality monitoring occasions and a number of PDCCH candidates in a plurality of PDCCH monitoring occasions. (Paragraph 0082 discloses formula 1 for the determination of the CCE Index. Formula 1 is a function of the number of CCEs and the number of PDCCHs in multiple monitoring occasions. Whereby “NccE,p is the number of CCEs in CORESET p, and the indexes are from 0 to NccE, p - 1;”. And “… the number of PDCCH candidate positions with aggregation level L monitored on carrier nc1 and search space sets;” Whereby paragraph 0199 discloses “In a possible implementation, control channel elements CCEs of PDCCH candidate positions corresponding to the repetitively transmitted PDCCH at the N monitoring times are the same.” Response to Arguments Applicants’ arguments with respect to claims 1, 12 and 25 have been considered but are moot because the new ground of rejection does not rely on any reference applied in the prior rejection of record for any teaching or matter specifically challenged in the argument. Conclusion THIS ACTION IS MADE FINAL. Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a). A shortened statutory period for reply to this final action is set to expire THREE MONTHS from the mailing date of this action. In the event a first reply is filed within TWO MONTHS of the mailing date of this final action and the advisory action is not mailed until after the end of the THREE-MONTH shortened statutory period, then the shortened statutory period will expire on the date the advisory action is mailed, and any nonprovisional extension fee (37 CFR 1.17(a)) pursuant to 37 CFR 1.136(a) will be calculated from the mailing date of the advisory action. In no event, however, will the statutory period for reply expire later than SIX MONTHS from the mailing date of this final action.
