1. An apparatus for wireless communication at a first wireless communication device, comprising:
memory; and
one or more processors, coupled to the memory, configured to:
receive a configuration associated with reporting delta channel state information (CSI) for sidelink;
compute, using the configuration, the delta CSI in association with a sidelink connection between the first wireless communication device and a second wireless communication device,
wherein the delta CSI indicates a difference between first CSI, associated with a first connection between the first wireless communication device and a base station, and second CSI associated with the sidelink connection; and
transmit a CSI report using the configuration, the CSI report including an indication of the delta CSI and at least one of:
an indication of the first CSI, wherein the delta CSI provides information associated with the second CSI associated with the sidelink connection, or
an indication of the second CSI associated with the sidelink connection,
wherein the delta CSI provides information associated with the first CSI.
