Abstract

The invention provides a wireless energy transmission method and device. The method is applied to a server in a wireless energy-driven communication network. By calculating the optimal confidence beamforming vector of a multi-antenna transmitter and the optimal power separation ratio vector of a single antenna receiver unit, each single antenna power separation structure receiver separates a received radio frequency signal into a first signal which satisfies the signal interference noise ratio constraint and a second signal which satisfies the radio frequency power constraint. All single antenna power separation structure receivers can simultaneously decode the information and acquire enough work energy.
