摘　　要：无线异构网络要求实现不同工作模式通信系统间的资源合理分配。为了获得不同通信系统对无线资源的有效利用,参考XG架构定义了可承载不同通信系统业务需求的多维度资源容器,提出二级资源分配策略及相应的资源分配算法来实现多维度资源容器与各个通信系统之间各种业务承载需求的匹配。仿真与性能分析验证了该资源分配策略在实现不同通信系统共存的条件下,提高了无线网络频谱资源利用率。The wireless heterogeneous networks require efficient resource allocation between different communication systems with different modes.To gain effective wireless resource utilization between different systems,a resource allocation strategy based on XG system architecture was proposed.And then a multidimensional resource container was presented,which can meet the traffic demands of different communication systems.A two-level resource allocation strategy and its corresponding resource allocation algorithm were utilized to match the multidimensional resource container with diversified traffic demands between different communication systems.The simulation and performance analysis show that the proposed strategy can improve wireless frequency resource utilization and satisfy the traffic demands between different communication systems.
