1. A method for wireless communication performed by a first wireless communication device, the method comprising:
receiving, from a second wireless communication device, one or more signals for each of a plurality of candidate sensing beams and a transmission beam;
determining, for each of the plurality of candidate sensing beams based on at least one of the one or more signals, a first signal measurement with respect to at least one of a direction of the transmission beam or a direction of the respective candidate sensing beam;
determining, based on at least one of the one or more signals for the transmission beam, a second signal measurement with respect to the direction of the transmission beam; and
determining, for each of the plurality of candidate sensing beams based on the respective first signal measurement and the second signal measurement, beam coverage information with respect to the direction of the transmission beam, wherein the determining the beam coverage information comprises:
determining, for at least a first candidate sensing beam of the plurality of candidate sensing beam directions, a quasi co-location (QCL) relationship between the respective candidate sensing beam direction with respect to the transmission beam direction.
