performing, by the first UE, partial sensing during a sensing window of the first UE by monitoring for sidelink transmissions from a plurality of UEs comprising a second UE and a third UE, wherein the monitoring comprises using different beams comprising at least a first beam for a first duration at a first time during the sensing window to monitor the sidelink transmissions from the second UE and a second beam for a second duration at a second time during the sensing window to monitor the sidelink transmissions from the third UE; and

selecting, by the first UE, resources, within a resource selection window, for future sidelink communications based on results of the partial sensing.
