1. A method for discontinuous reception (DRX) for use in a wireless transmit/receive unit (WTRU) configured for sidelink (SL) communication, the method comprising:
receiving SL DRX configuration information from a peer SL WTRU, wherein the SL DRX configuration information comprises timer information, wherein the timer information comprises at least a SL on-duration timer, a SL inactivity timer, a SL hybrid automatic repeat request (HARQ) round trip time (RTT) timer, and a SL HARQ retransmission timer;
accepting the received SL DRX configuration information; and
sending, on a condition that the WTRU has a radio resource control (RRC) connection to a base station, a message to the base station, wherein the message indicates that the WTRU accepted the received SL DRX configuration information from the peer SL WTRU, wherein the message is sent in an RRC information element, and wherein the message indicates the accepted SL DRX configuration information including at least the SL on-duration timer and a SL DRX slot offset.
