1. A user equipment (UE) associated with a wireless communication network, the UE comprising:
one or more processors configured to:
form a sidelink group with one or more other UEs associated with the wireless communication network;
receive a sidelink (SL) groupcast message from a select UE of the one or more other UEs of the sidelink group, the SL groupcast message comprising a SL channel state information (CSI) request and a transmission of a SL channel state information reference signal (CSI-RS);
in response to receiving the SL groupcast message:
determine a designated transmit (Tx) UE of the one or more other UEs based on the designated Tx UE being a furthest distance from the UE relative to other UEs of the one or more other UEs; and
provide an SL CSI report, derived based on a measurement of the SL CSI-RS, to the designated transmit (Tx) UE.
