Macro-Femto双层网络中资源分配策略
A Resource Allocation Policy for Macro-Femto Double-layer Network
摘要
Abstract
The coexistence of macro cells and low-power cells forming the heterogeneous double-tiered networks,can effectively improve the capacity of communications systems,solving the situation of data business congestion. However,the interferences between the macro cells and Femto cells severely degrade the quality of communications and prevent the system quality enhanced. Aiming at this problem, propose a hierarchical scheduling resource-joint interference suppression algorithm. First,build a model of the inner and outer layer of the system ( I-O model) ,and analyze the double-cross hybrid interference. Then,put forward an algorithm of resource allocation of time-frequency domain resource scheduling and based on joint subcarrier and power in inner and outer layer. Finally,simulate them on the sys-tem platform. The results show that the algorithm proposed achieves good effects in the spectrum efficiency of the system,the average user throughput and other aspects.关键词
