【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]:In order to solve the problem of colayer interference caused by common frequency deployment of femto cell, a fully distributed proportional resource allocation algorithm with quality of service (QoS) assurance is proposed. Based on the game theory to minimize interference, the algorithm designs a halving allocation strategy and a probability abandonment strategy. The allocation halving policy is based on the user's requirements and the limited resources available in the network. The probabilistic abandonment strategy enables the interfering cell to abandon the corresponding resources based on the probability to reduce the interference. The simulation results show that the proposed algorithm ensures the fairness of resource allocation between femto cells and improves the efficiency and convergence of spectrum multiplexing. This algorithm provides simple and effective scheme support for the deployment of femto cells without any additional information exchange in the current cellular network.
