Abstract

The embodiments of the invention provide a wireless energy transmission method and system. The method comprises: acquiring uplink pilot information sent by a terminal, and estimating downlink channel information according to the uplink pilot information; calculating an initial pre-coding combination coefficient based on large-scale channel fading information, a reference transmitting power value and the number of antennas; calculating an initial Lagrange multiplier based on the large-scale channel fading information, the initial pre-coding combination coefficient and a preset pre-coding combination coefficient formula; broadcasting the initial Lagrange multiplier to other base stations, and receiving initial Lagrange multipliers sent by the other base stations and corresponding to the other base stations one by one; adjusting the transmitting power based on the Lagrange multiplier array and a power iteration formula; on the basis of the adjusted transmitting power, calculating a pre-coding combination coefficient after the transmitting power is updated, then calculating an energy code for pre-coding the energy to be transmitted, and transmitting the pre-coded energy to the terminal. The method and the system improve the energy transmission efficiency of multiple energy sources.

Description

technical field [0001] The present invention relates to the technical field of energy transmission, in particular to a wireless energy transmission method and system. Background technique [0002] At present, in addition to transmitting electric energy to terminal devices through common wired means, the way of transmitting electric energy through wireless means is increasingly required by people. Specifically, the existing wireless energy transmission technologies mainly include: coil coupling-based wireless energy transfer technology, radio frequency-based wireless energy transfer technology, and laser-based wireless energy transfer technology. The electric energy is converted into energy forms such as electromagnetic waves or radio frequency signals for transmission, and the terminal equipment then converts the received electromagnetic waves or radio frequency signals into electric energy, and finally realizes the transmission of electric energy. [0003] Since the radio ...
