Abstract

Methods, systems, and devices for wireless communication are described. The techniques described herein relate to beam sweeping to improve the range of wireless power transfer. An energy harvesting user equipment (UE) receives, from a network entity, an indication of a set of time resources associated with a beam sweeping transmission (e.g., polling operation) by the network entity and one or more frequency shifts associated with backscattering the beam sweeping transmission. The UE receives the beam sweeping transmission from the network entity in accordance with the set of time resources. The UE transmits a backscattered signal based on the beam sweeping transmission and the one or more frequency shifts. The UE receives, from the network entity, a beamformed power signal in accordance with transmitting the backscattered signal. The UE stores energy for powering the UE based on the beamformed power signal.
