Abstract
Embodiments of the present disclosure provide method and apparatus for SL DRX. A method performed by a terminal device comprises receiving system information block (SIB). The method further comprises determining whether an access network node is incapable of sidelink, SL, discontinuous reception (DRX). The method further comprises, when sidelink, SL, discontinuous reception, DRX, configuration used for groupcast/broadcast and/or configuration of a SL frequency is absent in the SIB, using preconfigured SL DRX configuration for groupcast/broadcast communication of the terminal device. The method further comprises, when a serving access network node of the terminal device is SL DRX incapable, informing a peer terminal device that the terminal device cannot adopt SL DRX for its transmission and/or forbidding transmitting groupcast/broadcast service when SL DRX is required to be configured.
