摘要/Abstract

摘要：

为解决毫微微小区共频部署带来严重的同层干扰问题，提出一个具有服务质量保证的全分布式比例资源分配算法．该算法在利用博弈论最小化干扰的基础上，设计了一个分配减半策略和一个概率放弃策略．分配减半策略根据用户需求以及网络中有限的可用资源为用户进行相应分配．概率放弃策略使干扰小区基于概率放弃相应资源以减少干扰．仿真结果表明，该算法保证了毫微微小区间资源分配的公平性，提高了频谱复用效率和收敛性．该算法在当前蜂窝网中不增加任何额外信息交换的情况下，为毫微微小区的部署提供了简单有效的方案支持．

Abstract:

A fully distributed proportional resource allocation algorithm with QoS (Quality of Service) guarantees has been proposed to solve the serious co-tier interference caused by the deployment of femtocells. Based on a potential game algorithm, we design a half-allocation strategy and a probabilistic quit strategy in which the finite resource can be allocated according to users’ demand and the interference resource can be quitted according to a probability distribution function. Simulation results show that this algorithm has excellent performance in fairness, spectrum spatial reuse and convergence. All the features verify that our algorithm is a simple and efficient solution for resource allocation in femtocell networks without any information exchange.

Key words: femtocell, resource allocation, interference mitigation, quality of service guarantee
