receiving, from the second UE on the first sidelink channel, a first control information comprising a trigger to measure an aperiodic reference signal based at least in part on the first timing configuration, wherein the first control information is relayed from the second UE to the first UE based at least in part on the first UE being out of coverage with respect to a network device;

receiving, from the second UE, the aperiodic reference signal on a second sidelink channel based at least in part on the received first control information; and

transmitting, to the second UE on a third sidelink channel, a channel state information report (CSI) prior to a termination of the first timing configuration.
