Abstract

The present application discloses a method for information and energy hybrid transmission based on a large scale antenna, which includes: receiving an orthogonal information pilot frequency sequence sent by an information request user, and a sharing energy pilot frequency sequence sent by an energy request user, wherein the information pilot frequency sequence and the energy pilot frequency sequence are orthogonal; based on the information pilot frequency sequence, generating a first precoding vector for the information request user; based on the energy pilot frequency sequence, generating a second precoding vector for the energy request user; and based on the first precoding vector and the second precoding vector, generating a sending signal and sending to the information request user and the energy request user. The information and energy hybrid transmission solution of the present application solves the problem in the prior art that the mobile terminal is inconvenient to be charged. The present application further discloses a device for information and energy hybrid transmission based on a large scale antenna.

Description

Technical field [0001] This application relates to the field of communication technology, and in particular to a method and device for mixed transmission of information and energy based on large-scale antennas. Background technique [0002] At present, wireless energy transmission technologies are mainly divided into two categories: one is based on coil coupling short-distance energy transmission, which can transmit energy within the wavelength range with 70% efficiency, but the distance between the energy receiving terminal and the energy transmitting terminal is limited. Larger restrictions. The other is the long-distance energy transmission based on radio frequency. Because radio frequency-based wireless energy transmission is similar to information transmission technology and has higher efficiency, more importantly, it can eliminate the last wired connection of the wireless communication network, making the mobile communication network a real The "wireless" communication net...
