Distributed base station system and networking method

Abstract

The invention discloses a distributed base station system and a networking method. At least one energy shared pool is arranged in the system, wherein the energy shared pool can store electric energy from a power grid, a baseband processing unit and a remote antenna unit, and can also supply power to the baseband processing unit, the remote antenna unit, and the power grid; energy of the energy shared pool is transmitted to the remote antenna unit and the baseband processing unit through a bidirectional transmission link; energy collected by the remote antenna unit and the baseband processing unit is transmitted to the energy shared pool through the bidirectional transmission link; and the electric energy bidirectional transaction of the power grid and the energy shared pool is completed through an intelligent electric meter. The distributed base station system provided by the invention can realize the sharing of the energy collected by the remote antenna unit and the baseband processing unit, and achieve flexible configuration of resources. According to the distributed base station system provided by the invention, under the condition that no power grid is used, through an energy sharing power distribution method and an information and energy cooperation method and the like, the system can also work effectively, thus the system reliability is improved, and the degree of dependence of the system on the power grid and the use cost are reduced.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a networking method for distributed base stations in a wireless EH network. Background technique [0002] Growing concerns about the energy consumption of wireless networks and the increase in Earth's temperature have prompted the development of more energy-efficient communication technologies. 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. [0003] Distributed base stations are usually composed of baseband processing units and remote antenna units (also known as radio frequency processing units), which have higher capacity and better coverage performance than traditional base stations. There are few results about distributed base statio...
