1. An apparatus for wireless communication, comprising:
a transceiver;
a memory configured to store instructions; and
one or more processors communicatively coupled with the transceiver and the memory, wherein the one or more processors are configured to:
receive, from a transmitting user equipment (UE) in sidelink communications, a sidelink transmission;
generate channel state information (CSI) for the sidelink transmission; and
transmit, to the transmitting UE and based on a CSI transmission timeline, the CSI over a physical sidelink feedback channel (PSFCH), wherein the CSI transmission timeline is associated with a minimum time gap for transmitting the CSI after receiving the sidelink transmission, and wherein the minimum time gap for transmitting the CSI is set to one of a plurality of different gap sizes depending on a type of the sidelink transmission that is used to generate the CSI.
