1. An apparatus for wireless communication by a first wireless device, the apparatus comprising:
a receiver configured to receive one or more instances of channel state information reference signals (CSI-RS);
at least one processor configured to:
generate one or more CSI reports for one or more of the CSI-RS instances; and
determine whether a time between reception of a first CSI-RS instance of the one or more CSI-RS instances and a potential data transmission from the first wireless device is less than or equal to a maximum time delay; and
a transmitter configured to:
transmit a first CSI report, of the one or more CSI reports, for the first CSI-RS instance, being multiplexed with data in a physical sidelink shared channel (PSSCH) transmission when the time between the reception of the first CSI-RS instance and the potential data transmission is less than or equal to the maximum time delay; and
transmit the first CSI report, of the one or more CSI reports, for the first CSI-RS instance, without multiplexing the first CSI report with the data in the PSSCH transmission when the time between the reception of the first CSI-RS instance and the potential data transmission is greater than the maximum time delay.
