Abstract

The invention discloses an antenna selection and resource allocation method in a wireless energy supply communication network. The wireless energy supply communication network constructed by the method is a multi-user network architecture based on an orthogonal frequency division multiplexing technology, and comprises a hybrid access point; the hybrid access point is connected with K users downwards; and each user has two antennas for transceiving radio frequency signals. The method is based on an energy self-recovery technology; by combining antenna selection and resource optimal allocation,under the energy causality constraint, a total data rate of the users is maximized, resource allocation efficiency in the wireless power supply communication network is promoted, and the total data rate of all the users is maximized.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a method for antenna selection and resource allocation in a wireless power supply communication network, which can be implemented based on self-energy recovery technology in a wireless power supply communication network, and combined with antenna selection and network resource allocation , to maximize the user transmission data rate. Background technique [0002] The issue of limited device battery life has always constrained the development of modern wireless communication technologies. The emergence of radio frequency wireless energy transmission technology provides a feasible way to solve this problem, and then a communication architecture called wireless power supply communication network appeared based on this technology. In this architecture, wireless devices use the energy collected by radio frequency signals to transmit information, which has very im...
