1. A method of wireless communication at a first user equipment (UE), the method comprising:
receiving, from a base station over a downlink channel, a configuration indicating a predetermined percentage;
determining whether a data signal associated with a groupcast transmission from a second UE is decodable at the first UE;
obtaining one or more measurements of the data signal when the data signal is decodable at the first UE;
determining a threshold based on a percentage of lowest measured reference signal received power (RSRP) values, the percentage being configured to correspond to the predetermined percentage;
determining whether the one or more measurements exceed the threshold; and
transmitting a first type of feedback to the second UE when the one or more measurements do not exceed the threshold.
