Problems solved by technology

However, the disadvantage of this architecture is that it cannot realize energy sharing between remote antenna units, and cannot realize flexible allocation of resources. It needs to purchase more power from the smart grid, which increases the cost of the system.

Abstract

The invention discloses a power distribution method for an energy-sharing EH distributed base station system. The technical scheme includes the steps: when the channel condition is good, more energy is distributed to the remote control unit, and when the channel condition is not good, less energy is distributed to the remote control unit, so that dynamic control over energy utilization is achieved, and utilization of collected energy is optimized. According to the power distribution method, dynamic balance between borrowing energy from the smart power grid and transmitting energy to the smartpower grid is realized, and the energy is preferentially used for sharing, and the power supply of the smart power grid can be reduced, and the dependence on the smart power grid and the use cost of the distributed base station system are reduced.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to resource sharing and 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. Energy harvesting (EH) technology, which obtains energy from renewable energy sources such as solar energy, wind energy, thermal energy and radio frequency energy, can drive communication equipment and networks. Among the results of wireless EH network distributed base station networking, there are literatures published A distributed base station architecture, which realizes wireless information and power simultaneous transmission on the downlink through arbitrarily distributed remote antenna units. The remote antenna units use EH techn...
