Abstract:
Method and apparatus for a WTRU to harvest energy from uplink signals of other WTRUs in a wireless network are disclosed. In an example, a method includes sending a message indicating resources and capability of energy harvesting (EH) from sets of resources of the plurality of resources; receiving one or more SRS super-sets, each SRS super-set being associated with a group of other WTRUs and at least one set of resources of the plurality of resources; determining a mapping between a receive beam and an SRS super-set; receiving uplink transmission patterns each being associated with an SRS super-set; selecting a receive beam from a set of receive beams based on the received uplink transmission patterns; and harvesting RF energy from uplink transmissions of one or more groups of other WTRUs using at least the selected receive beam and the received uplink transmission patterns.
