Problems solved by technology

However, the disadvantage of this architecture is that the energy collected by RAUs can only be used by itself or directly transmit excess energy to the smart grid, which cannot realize the dynamic allocation and sharing of energy between remote antenna units, resulting in waste of energy during transmission. , so that resources cannot be flexibly configured, and the dependence on the smart grid is high, which is not conducive to network deployment

Abstract

The invention discloses a dynamic power distribution method based on an EH distributed base station system. The purpose of the invention is to ensure that the energy collected by the EH remote antennaunit can be used by itself. Redundant energy can be conveyed to the energy sharing pool; and the energy sharing pool is shared by other EH remote antenna units, and whether the energy sharing pool transactions with the intelligent power grid is determined according to the amount of energy in the energy sharing pool, so that dynamic change of an energy transmission rate threshold value between theEH remote antenna units and the energy sharing pool and dynamic distribution of power are realized. According to the invention, dynamic balance of energy utilization is facilitated, and the performance of the system is improved.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to resource sharing and power allocation of a distributed base station system in a wireless EH network. Background technique [0002] A distributed base station system usually consists of a baseband processing unit (BPU) and a remote antenna unit (RAU), which has higher capacity and better coverage performance than traditional base stations. Among the results of distributed base station networking in wireless EH networks, some literature discloses a distributed base station architecture, which realizes simultaneous transmission of wireless information and power on the downlink through arbitrarily distributed remote antenna units. The remote antenna units use EH technology, and can trade collected energy with the smart grid for two-way energy flow. However, the disadvantage of this architecture is that the energy collected by RAUs can only be used by itself or directl...
