1. A method for wireless communication at a user equipment (UE), comprising:
receiving a downlink control information message scheduling a downlink transmission that comprises a zero-power reference signal for the UL to use for rate matching during the downlink transmission;
receiving a signal triggering transmission of an aperiodic reference signal during the downlink transmission;
determining whether the UE supports search space sharing;
performing, upon determining that the UE supports search space sharing, rate matching around the aperiodic reference signal; and
refraining from performing, upon determining that the UE does not support search space sharing, rate matching around the aperiodic reference signal.
