1. A 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 UE to:
transmit a reference signal to a device on a sidelink (SL) transmission;
receive a channel quality report from the device; and
decode the channel quality report to obtain a channel quality;
wherein the at least one processor is configured to cause the UE to be configurable to support:
a reporting activation scheme in which a SL channel status information (CSI) reporting activation indicator is configured; and
a measurement triggering scheme that initiates transmission of the reference signal upon satisfying a triggering condition, wherein the triggering condition comprises a flag in sidelink control information (SCI).
