1. A method, performed by a first user equipment (UE) in a connected mode with a gNB, of entering sidelink (SL) discontinuous reception (DRX), the method comprising:
receiving from the gNB a Uu DRX medium access control (MAC) control element (CE) layer-2 command triggering the first UE to enter either Uu or SL DRX indicated in the Uu DRX MAC CE layer-2 command;
receiving radio resource control (RRC) signaling, wherein the RRC signaling configures a look up table indicating the Uu DRX MAC CE layer-2 command comprises a DRX configuration, and wherein the look up table includes two different tables and the Uu DRX MAC CE layer-2 command includes a flag to indicate which table is used; and
processing the Uu DRX MAC CE layer-2 command to determine whether to enter Uu DRX or SL DRX with a second UE.
