Abstract

The invention relates to a network energy efficiency improving method based on cluster and geometric water injection resource distribution, and belongs to the technical field of mobile communication.Firstly, an optimal matching scheme based on load balancing is provided to ensure load balancing of base stations in the network, so that network resources can be configured reasonably, and flow congestion can be reduced; secondly, in order to reduce the interference in the network, small cellular base stations in the cellular heterogeneous network are clustered, cluster heads are selected according to the energy efficiency, and the cluster heads redistribute resources in the cluster; thirdly, according to a geometric water injection algorithm, an energy efficiency-based channel power distribution scheme is provided; and finally, the small cell base station cluster, the channel power distribution and the dynamic small cell base station on/off are combined, and the energy efficiency is further improved under the condition that the network interruption probability, the lowest signal to interference plus noise ratio requirement of the user equipment and the communication quality of the UEin the core area are ensured.

Description

technical field [0001] The invention belongs to the technical field of mobile communication, and relates to a method for improving network energy efficiency based on cluster and geometric water injection resource allocation. Background technique [0002] In order to welcome the arrival of the Internet of Everything era, a new generation of wireless communication technology—5G (5th-Generation) is being researched, tested and deployed all over the world, and it is expected to be commercialized in 2019-2020. In the 5G era, there are a large number of terminal smart devices, which will generate massive amounts of information and data, which poses a huge challenge to the capacity of the network. Therefore, as an effective method for 5G communication, cellular heterogeneous networks (Heterogeneous Cellular Networks, HCNs) consist of macrocellular networks and small cellular networks. In a traditional macrocellular network, a macro base station (MacrocellBaseStation, MBS) provides...
