Abstract

The invention discloses an energy sharing and power distribution method of an EH distributed base station system. A definition is shown in the description, N is the number of remote antenna elements;M is the number of antennas configured for each remote antenna unit; gi is an M * 1 dimension channel vector; wi is a beamforming column vector of the remote antenna element i, the length is M and | |wi | |<2>=1. The method is obtained by solving the following optimization problem: (shown in the description). The present invention can realize the share of the collected energy of the EH distributebase station system among the components within the system, on the premise of minimizing the power supply of smart grid, the optimal power distribution can be obtained and the transmission rate of the system can be improved. Moreover, by preferentially using the collected energy, the dependency on smart grid and the cost of distributed base station system are reduced.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a method for resource sharing and power allocation of a distributed base station system in a wireless EH network. Background technique [0002] Energy harvesting (EH) technology, which obtains energy from renewable energy sources such as solar energy, wind energy, thermal energy, and radio frequency (RF) energy, can drive communication devices and networks, showing bright prospects for realizing green communication. A distributed base station usually consists of a baseband processing unit and a remote antenna unit (also called a radio frequency processing unit), and has higher capacity and better coverage performance than traditional base stations. There are few technical achievements about distributed base station networking in wireless EH networks. A distributed base station architecture has been disclosed. The MIMO distributed antenna system realizes wireless in...
