US 12,224,595 B2 · Method of network-assisted beamformed energy harvesting signaling and corresponding apparatus

Abstract

A wireless transmit/receive unit, WTRU, may include an Energy Harvesting device, EH, a Zero Energy transceiver, ZE, and a main transceiver. The WTRU may initialize operation using the main transceiver, and receive beam detection configuration and mapping information. The WTRU may initialize beam (re-) selection procedure using the ZE transceiver, and use the received beam detection configuration to determine detectable beam IDs. and use the received mapping information to retrieve EH signaling configuration. The WTRU determines expected EH performance for each detected beam, and selects the beam with best expected EH performance. On condition that the WTRU determines necessity of dynamic EH signaling for the selected beam, it proceeds with presence declaration procedure to request optimized dynamic EH signaling. The WTRU utilizes control signaling channel parameters to dynamically receive optimized EH signal configuration, and configures its EH circuitry, and harvests energy.
