Preferably, the first device may (re-)start the DRX HARQ RTT timer in response to reception of the SL HARQ-ACK feedback. The PSCCH or PSSCH transmission may be the last reserved PSCCH/PSSCH transmission for a same data packet before performing the sidelink resource reselection. Preferably, the second device may start or restart the DRX retransmission timer (for sidelink) when the DRX HARQ RTT timer expires.”), wherein the second feedback information indicates a negative acknowledgment based at least in part on the first UE failing to receive feedback responsive to the second sidelink message during a duration of the feedback timer ([0360], “The first sidelink resource may not be selected for a PSSCH retransmission based on detecting HARQ-ACK feedback as NACK. The first device may select, determine, or acquire a second sidelink resource for PSCCH retransmission and/or PSSCH retransmission (to the second device) without basing on (sidelink) DRX operation of the second device.”). It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have modified Hosseini 737 in view of Li to have the feedback time expiring and transmission of the second feedback based on expiry of the timer. The motivation would have been to reduce power consumption (e.g., Li [0317]).
Regarding claim 28, Hosseini 737 does not disclose the feedback timer based on a preconfigured timer. Li discloses the apparatus of claim 26, wherein a duration of the feedback timer is based at least in part on a priority associated with the feedback information, a configured value, a preconfigured value, or a level of congestion associated with sidelink data traffic, or any combination thereof ([0371], “The Tx UE may select a first sidelink resource from the valid sidelink resource set to perform sidelink transmission to the Rx UE. As shown in FIG. 10(a), the (sidelink) active time of the Rx UE after the sidelink resource (re-)selection trigger is fully within time interval of selection window [n+T.sub.1, n+T.sub.2]. The Tx UE may derive or determine the set of candidate slots, where the set of candidate slots comprise (all) slots of the (sidelink) active time of the Rx UE.”). It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have modified Hosseini 737 in view of Li to have the feedback timer based on a preconfigured timer. The motivation would have been to reduce power consumption (e.g., Li [0317]).
Claims 17-19 are rejected under 35 U.S.C. 103 as being unpatentable over Hosseini et al. (US 2022/0200737; hereinafter Hosseini 737) in view of Lee et al. (US 2023/0363052).
Regarding claim 17, Hosseini 737 does not disclose the channel sensing procedure. Lee discloses the apparatus of claim 1, wherein the sidelink shared channel resource comprises a shared radio frequency spectrum band resource, and wherein, to select the sidelink shared channel resource, the instructions are executable by the at least one processor to cause the apparatus to: select the sidelink shared channel resource based at least in part on performing a channel sensing procedure on a set of candidate resources including the sidelink shared channel resource ([0176], “FIG. 10 illustrates a method of selecting slots for transmitting a control channel and a data channel by sensing in a resource pool for transmission of the control channel (PSCCH) and the data channel (PSSCH) related thereto.”). It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have modified Hosseini 737 in view of Lee to have the channel sensing procedure. The motivation would have been to increase resource efficiency (e.g., Lee [0100]).
Regarding claim 18, Hosseini 737 does not disclose the type of channel sensing. Lee discloses the apparatus of claim 17, wherein the instructions are further executable by the at least one processor to cause the apparatus to: receive an indication of a type of channel sensing procedure, wherein the channel sensing procedure comprises the indicated type of channel sensing procedure ([0202], “Therefore, for V-UE, a sensing-based resource selection method (hereinafter, a full sensing method) may be applied to all of the resources within a specific duration (e.g., 1000 ms corresponding to a duration from “TTI m-a” to “TTI m-b”). Meanwhile, for P-UE, a sensing-based resource selection method (hereinafter, a partial sensing method) is required with respect to some resources within a specific duration (e.g., 1000 ms corresponding to the duration from “TTI m-a” to “TTI m-b”) to save power consumption.”). It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have modified Hosseini 737 in view of Lee to have the type of channel sensing. The motivation would have been to increase resource efficiency (e.g., Lee [0100]).
Regarding claim 19, Hosseini 737 does not disclose the type of channel sensing in the sidelink message. Lee discloses the apparatus of claim 18, wherein the sidelink message ([0198], “The second UE may identify a SL resource through which the first UE is to transmit SL data through the PSSCH based on the first and second SCI received from the first UE. The second UE may receive the SL data from the first UE through the PSSCH on the identified resource.”) comprises the indication of the type of channel sensing procedure ([0196], “Meanwhile, in the UE autonomous resource selection mode (or mode 2), the UE autonomously determines a slot in which the SA is transmitted within the resource pool through sensing and a resource block that is a frequency axis resource used for transmission of the SA within the slot in which the SA is transmitted may be autonomously determined by the UE within the resource pool.”). It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have modified Hosseini 737 in view of Lee to have the type of channel sensing in the sidelink message. The motivation would have been to increase resource efficiency (e.g., Lee [0100]).
