Office Action

§102
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 . This office action is in response to Applicant’s preliminary amendment filed on 2/1/2024. Claims 15-34 are currently pending. Claim Rejections - 35 USC § 102 In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status. 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)(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. Claims 15-34 are rejected under 35 U.S.C. 102(a)(2) as being anticipated by Takeda et al. (US 2022/0322292 A1; hereafter TAKEDA). With respect to claim 15, TAKEDA discloses a user equipment (UE) (802, UE in FIG. 8; 902, UE in FIG. 9) for wireless communication, comprising: at least one memory (376 in FIG. 3); and at least one processor (370 in FIG. 3) coupled with the at least one memory and configured to cause the UE to: receive configuration information of a physical uplink control channel (PUCCH) resource pool for a group of UEs receiving a multicast transmission, wherein the group of UEs comprises the UE (806, 808, 810 in FIG. 8; 906, 908, 910 in FIG. 9; 1502, 1510, 1520 in FIG. 15); receive a hybrid automatic repeat request acknowledgement (HARQ-ACK) feedback mode indication, wherein the HARQ-ACK feedback mode indication indicates a HARQ-ACK feedback mode for the multicast transmission from a plurality of HARQ-ACK feedback modes (806, 808, 810 in FIG. 8; 906, 908, 910 in FIG. 9; 1502, 1510, 1520 in FIG. 15); and determine, based at least in part on the indicated HARQ-ACK feedback mode, a PUCCH resource from the PUCCH resource pool for transmitting HARQ-ACK feedback for the multicast transmission (806, 808, 810 in FIG. 8; 906, 908, 910 in FIG. 9; 1502, 1510, 1520 in FIG. 15).
