摘要

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may provide, to a physical layer from a higher layer, an indication of a set of sidelink resources or slots that are for an active time of a discontinuous reception (DRX) cycle of a second UE or destination identifier (ID) and that are not for an inactive time of the DRX cycle of the second UE or destination ID. The first UE may transmit, to the second UE or one or more UEs associated with the destination ID, a sidelink communication that is based at least in part on the set of sidelink resources or slots. Numerous other aspects are described.

說(shuō)明書(shū)

As shown by reference number 715, the higher layer may select sidelink resources based at least in part on information about the DRX cycle of UE 404 (and a DRX cycle of UE 402, if applicable). In some aspects, the higher layer of UE 402 may select resources from the candidate set of sidelink resources such that the initial transmission and, potentially, one or more retransmissions are in the DRX active time of UE 404 or of one or more UEs associated with a destination ID.

As shown by reference number 720, the higher layer of UE 402 may cause the PHY layer of UE 402 to transmit a communication that includes a sidelink resource reservation of the sidelink resources to UE 404, or to one or more UEs associated with a destination ID. In some aspects, the higher layer of UE 402 may cause the PHY layer of UE 402 to transmit a sidelink communication (e.g., data, SCI) using a selected sidelink resource. By utilizing DRX cycle information for sidelink resource selection, UE 402 may avoid communications while UE 404 is asleep and conserve processing resources and signaling resources.

As indicated above, FIG. 7 is provided as an example. Other examples may differ from what is described with regard to FIG. 7.

FIG. 8 is a diagram illustrating an example process 800 performed, for example, by a first UE, in accordance with the present disclosure. Example process 800 is an example where the first UE (e.g., UE 120, UE 402) performs operations associated with sidelink resource selection for DRX.
