1. A method implemented in a wireless transmit/receive unit (WTRU) for wireless communications, the method comprising:
receiving one or more aggregations of sounding reference signal (SRS) schedules, wherein an aggregation of SRS schedules is associated with a group of other WTRUs;
performing measurements of uplink transmissions of at least one other WTRU from the group of other WTRUs using the one or more aggregations of SRS schedules;
determining a receive beam of the WTRU, for the one or more aggregation of SRS schedules, to be used for energy harvesting based on the measurements of uplink transmissions; and
harvesting radio frequency energy from an uplink transmission of the at least one other WTRU from the group of other WTRUs using the determined receive beam.
