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.

This Patent Application claims priority to U.S. Provisional Patent Application No. 63/261,992, filed on Oct. 1, 2021, entitled “SIDELINK RESOURCE SELECTION FOR DISCONTINUOUS RECEPTION,” and assigned to the assignee hereof. The disclosure of the prior Application is considered part of and is incorporated by reference into this Patent Application.
Aspects of the present disclosure generally relate to wireless communication and to techniques and apparatuses for selecting sidelink resources for discontinuous reception.
Wireless communication systems are widely deployed to provide various telecommunication services such as telephony, video, data, messaging, and broadcasts. Typical wireless communication systems may employ multiple-access technologies capable of supporting communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power, or the like). Examples of such multiple-access technologies include code division multiple access (CDMA) systems, time division multiple access (TDMA) systems, frequency division multiple access (FDMA) systems, orthogonal frequency division multiple access (OFDMA) systems, single-carrier frequency division multiple access (SC-FDMA) systems, time division synchronous code division multiple access (TD-SCDMA) systems, and Long Term Evolution (LTE). LTE/LTE-Advanced is a set of enhancements to the Universal Mobile Telecommunications System (UMTS) mobile standard promulgated by the Third Generation Partnership Project (3GPP).

What is claimed is:1. A first user equipment (UE) for wireless communication, comprising:a memory; and one or more processors, coupled to the memory, configured to: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 and that are not for an inactive time of the DRX cycle of the second UE; and transmit, to the second UE, a sidelink communication that is based at least in part on the set of sidelink resources or slots. 2. The first UE of claim 1 , wherein the sidelink communication includes a data communication that is scheduled for a sidelink resource within the set of sidelink resources or slots. 3. The first UE of claim 1 , wherein the sidelink communication includes sidelink control information that indicates a sidelink resource reservation within the set of sidelink resources or slots. 4. The first UE of claim 1 , wherein the one or more processors are configured to use sidelink resources in the set of sidelink resources or slots as an initial set of candidate sidelink resources for sidelink resource selection. 5. The first UE of claim 1 , wherein the one or more processors are configured to use, for sidelink resource selection, sidelink resources that are both within the set of sidelink resources or slots and within a resource selection window as an initial set of candidate sidelink resources. 6. The first UE of claim 1 , wherein the indication of the set of sidelink resources or slots identifies one or more sidelink resources. 7. The first UE of claim 1 , wherein the indication of the set of sidelink resources or slots indicates one or more ranges of slots. 8. The first UE of claim 1 , wherein the indication of the set of sidelink resources or slots indicates one or more ranges of time points. 9. The first UE of claim 1 , wherein the one or more processors, to provide the set of sidelink resources or slots, are configured to provide the set of sidelink resources or slots per priority of a transmission. 10. The first UE of claim 1 , wherein the set of sidelink resources or slots applies to a subset of transmissions. 11. The first UE of claim 10 , wherein the subset of transmissions is configured or preconfigured per resource pool or indicated via a radio resource control message. 12. A first user equipment (UE) for wireless communication, comprising:a memory; and one or more processors, coupled to the memory, configured to:generate, at a physical layer, a set of candidate sidelink resources; provide the set of candidate sidelink resources from the physical layer to a higher layer; and select, at the higher layer, sidelink resources for one or more transmissions that are within an active time of a discontinuous reception (DRX) cycle of a second UE and that are not within an inactive time of the DRX cycle of the second UE. 13. The first UE of claim 12 , wherein the one or more processors are configured to transmit, to the second UE, a sidelink communication that is based at least in part on the set of sidelink resources. 14. The first UE of claim 13 , wherein the sidelink communication includes a data communication that is scheduled for a sidelink resource within the set of sidelink resources. 15. The first UE of claim 13 , wherein the sidelink communication includes sidelink control information that indicates a sidelink resource reservation within the set of sidelink resources. 16. The first UE of claim 12 , wherein the set of sidelink resources applies to a subset of transmissions. 17. The first UE of claim 16 , wherein the subset of transmissions is configured or preconfigured per resource pool or indicated via a radio resource control message. 18. The first UE of claim 12 , wherein the one or more processors, to select the sidelink resources, are configured to select the sidelink resources based at least in part on a priority of a transmission. 19. The first UE of claim 12 , wherein the one or more transmissions includes an initial transmission. 20. A method of wireless communication performed by a first user equipment (UE), comprising:providing, 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 and that are not for an inactive time of the DRX cycle of the second UE; and transmitting, to the second UE, a sidelink communication that is based at least in part on the set of sidelink resources or slots. 21. The method of claim 20 , wherein the sidelink communication includes a data communication that is scheduled for a sidelink resource within the set of sidelink resources or slots. 22. The method of claim 20 , wherein the sidelink communication includes sidelink control information that indicates a sidelink resource reservation within the set of sidelink resources or slots. 23. The method of claim 20 , wherein the indication of the set of sidelink resources or slots identifies one or more sidelink resources. 24. The method of claim 20 , wherein the indication of the set of sidelink resources or slots indicates one or more ranges of slots. 25. The method of claim 20 , wherein the indication of the set of sidelink resources or slots indicates one or more ranges of time points. 26. The method of claim 20 , wherein the set of sidelink resources or slots applies to a subset of transmissions. 27.
