Regarding claim(s) 3,19, Luo discloses wherein the determining the size of the MCST is further based on a quantity of consecutive slots available in a set of candidate resources (See ¶ 48, the first indication information is carried in the DCI; the first indication information includes subcarrier indication information, resource allocation indication information, and repetition quantity indication information; the subcarrier indication information is used to determine a quantity N.sub.sc.sup.RU of consecutive subcarriers occupied by TB.sub.k in one RU; the resource allocation indication information is used to determine a quantity N.sub.RU of RUs to which an uplink data channel carrying TB.sub.k is mapped Regarding claim(s) 4, Luo discloses wherein the determined size of the MCST is less than or equal to the MCST size threshold.(See ¶ 276, M.sub.rep.sup.NPUSCH is greater than or equal to a threshold C, or N.sub.RU is greater than or equal to a threshold D, or M.sub.rep.sup.NPUSCH×N.sub.RU×N.sub.slots.sup.UL is greater than or equal to a threshold E, where N.sub.slots.sup.UL a quantity of consecutive slots in one RU). Regarding claim(s) 5, Luo discloses wherein the MCST comprises consecutive slots, and wherein the consecutive slots comprise one or more of: consecutive sidelink (SL) logical slots; or SL physical slots (See Fig(s). 2, See ¶ 211, 5. The terminal device 5 may send the downlink information to the terminal device 4 and the terminal device 6 based on a device-to-device (device-to-device, D2D) technology.). Regarding claim(s) 6, Luo discloses wherein each TB, of the one or more TBs, occupies at least one slot of the MCST (See ¶ 184,290, See Fig(s). 6 one TB unit is transmitted within one slot). Regarding claim(s) 8,11,18, Luo discloses wherein the determined size of the MCST is a minimum of the MCST size threshold and the size of the one or more TBs (See ¶ Table 4, TB size determines the slot threshold). Regarding claim(s) 9,12, Luo discloses wherein the determining the size of the MCST comprises setting the size as a lower of: the MCST size threshold; the size of the one or more TBs; and a quantity of consecutive slots available in set of candidate resources (See ¶ 9-11, 33-35, In a possible design, the first indication information includes a maximum repetition quantity R.sub.max of a downlink control channel; and when R.sub.max is greater than or equal to a first threshold, the terminal device determines that the target transmission mode is the interleaved transmission mode; or when R.sub.max is less than a first threshold, the terminal device determines that the target transmission mode is the sequential transmission mode.) Regarding claim(s) 13, Luo discloses wherein the determining the size of the MCST is further based on a quantity of consecutive slots available in a set of candidate resources (See ¶ 48, the first indication information is carried in the DCI; the first indication information includes subcarrier indication information, resource allocation indication information, and repetition quantity indication information; the subcarrier indication information is used to determine a quantity N.sub.sc.sup.RU of consecutive subcarriers occupied by TB.sub.k in one RU; the resource allocation indication information is used to determine a quantity N.sub.RU of RUs to which an uplink data channel carrying TB.sub.k is mapped 4. The method of claim 1, wherein the determined size of the MCST is less than or equal to the MCST size threshold.), sending, via the MCST and based on the size of the MCST being greater than a size of the one or more TBs, one or more second TBs (See Fig(s). 5 step 505, See ¶ 133, 260, 319). Regarding claim(s) 14, Luo discloses resending, via the MCST and based on a size of the MCST being greater than a size of the one or more TBs, a TB of the one or more TBs (See Fig(s). 1A-1C See ¶ 145, retransmission modes). Regarding claim(s) 15,20, Luo discloses wherein the sending the at least one of the one or more TBs via the MCST comprises sending the one or more TBs via the MCST, and wherein the method further comprises: resending, via the MCST, a portion of the one or more TBs, wherein a sum of a quantity of the one or more TBs and a quantity of the portion of the one or more TBs is less than or equal to a size of the MCST (See Fig(s). 1A-1C See ¶ 145, retransmission modes based on the size of the TBs to be sent). Regarding claim(s) 16, Luo discloses wherein the sending the at least one of the one or more TBs is based on a size of the MCST being less than a size of the one or more TBs See ¶ 33, 35, when M.sub.rep.sup.NPUSCH×N.sub.RU is less than a sixth threshold, the terminal device determines that the target transmission mode is the sequential transmission mode, where N.sub.slots.sup.UL is a quantity of consecutive slots in one RU.). Claim Rejections - 35 USC § 103 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 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 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, 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. Claim(s) 7 is/are rejected under 35 U.S.C. 103 as being unpatentable over Luo et al (US20220232615 A1 ) hereinafter as Luo in view of Chen et al (US 20210105760 A1) hereinafter as Chen. Regarding claim(s) 7, Chen discloses generating a sidelink grant for the MCST (See Fig(s). 1, See ¶ 29-30, A dynamic sidelink grant can be provided in a downlink control information (DCI), and schedule resources for an initial transmission of a transport block, and optionally, retransmissions of the same transport block.). Thus, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention, to incorporate the teachings of Chen within Luo, so as to ensure proper amount of resources are available between devices of the interest for sidelink communications.
