Abstract

A method of wireless communications by a sidelink UE (user equipment) includes receiving a first signal as part of a discontinuous reception (DRX) wake-up procedure at the beginning of a sidelink discontinuous reception (DRX) ON duration. The method also includes transmitting a response to the first signal as part of a DRX wake-up procedure. The method further includes starting a timer after sending the response. The method still further includes entering a sleep state upon not receiving a physical sidelink control channel (PSCCH) or physical sidelink shared channel (PSSCH) before the timer expires.
