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.
In order to solve the conflict problem of local resource scheduling in collaborative multi-point transmission (CoMP) system of users choosing collaborative set, a dynamic resource allocation method of collision avoidance is designed, and the cooperation is realized through subdivision and random assignment of collaborative resources The decoupling of resource allocation between nodes simplifies the negotiation process and avoids resource conflicts effectively, so that simple distributed local resource scheduling can be accomplished.The simulation results show that the proposed method can adapt to resource allocation in distributed scheduling scenario where users choose collaborative set The requirements of the system, and effectively improve the system’s edge spectrum efficiency and the overall spectrum efficiency.
