1. A method for detecting Sidelink Radio Link Failure (SL-RLF) implemented by a first wireless transmit-receive unit (WTRU) the method comprising:
determining to use at least one of a Radio Link Control (RLC)-based SL-RLF detection method or a Hybrid Automatic Repeat request (HARQ)-based SL-RLF detection method based on a Sidelink Radio Bearer (SLRB) configuration information, wherein the SLRB configuration information is associated with a Quality of Service (QoS) configuration for a unicast link between the first WTRU and a second WTRU;
determining that SL-RLF has occurred on the unicast link according to the determined SL-RLF detection method; and
transmitting, via a Radio Resource Control (RRC) message, information representative of the SL-RLF of the unicast link to a network node, wherein the information representative of the SL-RLF comprises an address of the second WTRU that indicates a destination address associated with the unicast link for which SL-RLF is detected.
