1. A method performed by a wireless transmit/receive unit (WTRU), the method comprising:
receiving configuration information indicating resources for receiving a first set of reference signals from one or more transmit/receive points (TRPs) using a first set of receive (Rx) beams, one or more first resource sets for transmitting a second set of reference signals, and one or more second resource sets for reporting sensing information for the second set of reference signals;
transmitting, in a plurality of spatial directions, the second set of reference signals using one of the one or more first resource sets;
measuring a backscatter power of at least a portion of the transmitted second set of reference signals;
reporting sensing information, based on the measured backscatter power of the at least the portion of the transmitted second set of reference signals, using one of the one or more second resource sets, the sensing information including information indicating one or more blockage statistics associated with at least a portion of the plurality of spatial directions; and
receiving the first set of reference signals from the one or more TRPs using a second set of Rx beams, wherein the second set of Rx beams is determined based on the reported sensing information.
