Method and apparatus for performing wireless communication related to sl drx in nr v2x

A first device adapted to perform wireless communication, the first device comprising:

• one or more memories storing instructions;
• one or more transceivers;
• and
• one or more processors connected to the one or more memories and the one or more transceivers, wherein the one or more processors execute the instructions to:
• obtain a sidelink (SL) discontinuous reception (DRX) configuration including information related to an SL DRX timer,
• wherein the SL DRX timer includes at least one of an SL DRX onduration timer or an SL DRX inactivity timer;
• obtain information related to a scheduling request (SR) configuration for a SL channel state information (CSI) reporting medium access control (MAC) control element (CE);
• determine the SR configuration for the SL CSI reporting MAC CE as an SR configuration for an SL DRX command MAC CE;
• transmit, to the base station, an SR for requesting a resource for the SL DRX command MAC CE, based on the SR configuration for the SL CSI reporting MAC CE;
• and
• transmit, to the second device, the SL DRX command MAC CE, based on the resource,
• wherein the SL DRX command MAC CE is information for stopping at least one of the SL DRX onduration timer or the SL DRX inactivity timer.

An apparatus adapted to control a first user equipment (UE), the apparatus comprising:

• one or more processors;
• and
• one or more memories operably connected to the one or more processors and storing instructions, wherein the one or more processors execute the instructions to:
• obtain a sidelink (SL) discontinuous reception (DRX) configuration including information related to an SL DRX timer,
• wherein the SL DRX timer includes at least one of an SL DRX onduration timer or an SL DRX inactivity timer;
• obtain information related to a scheduling request (SR) configuration for a SL channel state information (CSI) reporting medium access control (MAC) control element (CE);
• determine the SR configuration for the SL CSI reporting MAC CE as an SR configuration for an SL DRX command MAC CE;
• transmit, to the base station, an SR for requesting a resource for the SL DRX command MAC CE, based on the SR configuration for the SL CSI reporting MAC CE;
• and
• transmit, to the second UE, the SL DRX command MAC CE, based on the resource,
• wherein the SL DRX command MAC CE is information for stopping at least one of the SL DRX onduration timer or the SL DRX inactivity timer.
