1. A method of wireless communication performed by a transmit (Tx) user equipment (UE), comprising:
receiving, in a first downlink control information (DCI) 3_0 and from a network node, an uplink grant associated with enabling reporting of a particular channel state information (CSI) report, associated with a receive (Rx) UE, to the network node,
wherein the uplink grant indicates a destination identifier, associated with the Tx UE, indicating the particular CSI report;
transmitting, to the Rx UE and based at least in part on the first DCI 3_0, a request, for the particular CSI report, indicating the destination identifier;
receiving, from the Rx UE and based at least in part on transmitting the request, the particular CSI report;
adding, based at least in part on receiving the particular CSI report, a receiver identifier, identifying the Rx UE, to the particular CSI report; and
transmitting, to the network node and based on adding the receiver identifier to the particular CSI report, the particular CSI report,
wherein the particular CSI report is transmitted to the network node via a scheduling request procedure based at least in part on whether any uplink grant is available for the Tx UE to transmit the particular CSI report to the network node.
