Method and apparatus for sidelink communication

A user equipment (UE) for wireless communication, comprising:

• at least one memory;
• and
• at least one processor coupled with the at least one memory and configured to cause the UE to:
• obtain a plurality of sidelink (SL) discontinuous reception (DRX) configurations for SL communication, wherein the plurality of SL DRX configurations are configured based at least in part on a quality of service (QoS) related parameter;
• obtain, at a medium access control (MAC) layer of the UE from a higher layer of the UE, a mapping relationship between the QoS related parameter and at least one layer 2 (L2) destination identity (ID) associated with the MAC layer of the UE;
• determine, at the MAC layer of the UE and based at least in part on the mapping relationship, one or more SL DRX configurations of the plurality of SL DRX configurations for the at least one L2 destination ID associated with the MAC layer of the UE;
• and
• receive SL data based at least in part on respective active times associated with the one or more SL DRX configurations.
