异构蜂窝网络中面向能效的基站协作方案
Base station cooperation scheme for energy efficiency in heterogeneous cellular networks
摘要
Abstract
Heterogeneous networks satisfy the increasing demand of communication.However,heterogeneous networks with the characteristics of large densities,various types and random deployment raise worries about energy consumption.The base station (BS) cooperation is used as one of solutions to reduce the interference between BSs.This paper studies an user-centric cooperation scheme and analyzes the energy efficiency performance based on the scheme.In the cooperation scheme,the target user selects BSs with cooperative radii.All the layers of BSs within the cooperative cluster jointly transmit the same data to the target user.Firstly,based on the stochastic geometry,the location of BSs in different layers is modeled as independent homogeneous Poisson point process (HPPP) with different intensities.Then,the ergodic rate expression is derived on the proposed cooperation scheme.Furthermore,a power minimization problem with minimum ergodic rate constraint is formulated and the optimal cooperative radii by the binary search algorithm are obtained.Simulation results indicate that the proposed clustering model in heterogeneous networks has better performance on energy consumption compared with the macro-only network.关键词
