Sidelink discontinuous reception configuration

A first user equipment (UE), comprising:

• at least one memory;
• and
• at least one processor coupled with the at least one memory and configured to cause the first UE to:
• initiate a sidelink unicast establishment procedure with a second UE;
• perform sidelink communication using a predetermined sidelink discontinuous reception (DRX) configuration during the sidelink unicast establishment procedure;
• and
• in response to receiving a direct communication accept message, perform sidelink communication based on a set of sidelink DRX configurations.

A processor for wireless communication, comprising:

• at least one controller coupled with at least one memory and configured to cause the processor to:
• receive information, at a second user equipment (UE), indicating initiation of a sidelink unicast establishment procedure with a first UE;
• perform sidelink communication using a predetermined sidelink discontinuous reception (DRX) configuration during the sidelink unicast establishment procedure;
• and
• in response to transmitting a direct communication accept message, perform sidelink communication based on a set of sidelink DRX configurations.

A second user equipment (UE), the apparatus further comprising:

• at least one memory;
• and
• at least one processor coupled with the at least one memory and configured to cause the second UE to:
• receive information indicating initiation of a sidelink unicast establishment procedure with a first UE;
• perform sidelink communication using a predetermined sidelink discontinuous reception (DRX) configuration during the sidelink unicast establishment procedure;
• and
• in response to transmitting a direct communication accept message, perform sidelink communication based on a set of sidelink DRX configurations.
