15. A first user equipment (UE), comprising:
one or more memories; and
one or more processors coupled to the one or more memories, the one or more memories storing instructions that are executable by the one or more processors, individually or in any combination, to cause the first UE to:
transmit a request for a channel state information (CSI) report to a second UE;
transmit a reference signal to the second UE;
receive, from the second UE in response to the request, a first stage sidelink control information (SCI-1) on a physical sidelink control channel (PSCCH), a second stage sidelink control information (SCI-2) on the PSCCH, and a PSSCH wherein the SCI-2 is a layer 1 signal and includes the CSI report comprising one or more report fields;
decode the CSI report from the SCI-2 at a physical layer based on information indicated in the SCI-1; and
decode the PSSCH based on information indicated in the SCI-2,
wherein the one or more report fields includes at least one of a rank indicator, a channel quality indicator, or a precoding matrix index (PMI) indicator.
