摘要
为了解决用户选择协作集的协作多点传输(CoMP)系统中本地资源调度时的冲突问题,设计了一种冲突避免的动态资源分配方法.通过对协作资源的细分和随机指派,实现了协作节点间资源分配的解耦,简化了协商过程,有效避免了资源冲突,从而能完成简单的分布式本地资源调度.仿真结果表明,该方法能适应用户选择协作集的分布式调度场景下资源分配的要求,并有效提高系统的边缘用户频谱效率和整体频谱效率.
A dynamic resource allocation scheme is designed to implement user equipment（UE）-centric coordinated multi-point transmission（CoMP） in long term evolution advanced（LTE-A） system.The decomposition of cooperate resources is used to decouple the resource among the cooperation transmission points,and the random resource allocation is used to reduce the negotiation among the cooperation transmission points.Also,a simplex local scheduling can be implemented with less resource conflict.It is proved by simulation that the scheme can effectively outperforms on both the average sector spectrum efficiency and cell-edge UEs＇ spectrum efficiency.
