1. An apparatus for wireless communication at a responding sidelink user equipment (UE), comprising:
a memory; and
at least one processor coupled to the memory, the memory and the at least one processor configured to:
receive, from an initiating sidelink UE, a request to provide channel state information (CSI) feedback to the initiating sidelink UE, the request excluding a CSI reference signal (CSI-RS);
decode a transmission from the initiating sidelink UE to a neighboring sidelink UE, the transmission including a CSI feedback trigger; and
transmit, to the initiating sidelink UE, a CSI report based on the transmission.
