基于非合作博弈论的CoMP-JP资源分配算法

Resource allocation algorithm for CoMP-JP based on non-cooperative game theory

为了提高LTE-A系统中协作多点联合处理技术(Co MP-JP)的资源利用率,保证中心用户和边缘用户在资源分配过程中的公平性和Qo S需求,提出一种以最大化系统吞吐量为目的中心用户和边缘用户联合处理的动态资源分配方法。首先,在功率给定的情况,每个簇内以保证用户的Qo S需求并最大化系统吞吐量为目的进行用户调度;其次,在调度完成后,为了协调用户间的干扰,实现系统的吞吐量的最大化,提出改进代价函数的非合作博弈控制算法,并证明该算法纳什均衡解的存在性与唯一性。实验结果表明:本文算法与现有算法相比,更能满足用户的Qo S需求和用户间的公平性,同时获得更高的系统吞吐量。

In order to improve the resource utilization of collaboration multiple point joint processing（CoMP-JP） technique in LTE-A system and guarantee the resource allocation fairness between center users and edge source in the process, a joint processing method for the center users and the edge users of dynamic allocation of resources was proposed, with the purpose of maximizing system throughput. First of all, in the case of a given power, a scheduling algorithm that guarantees the user＇s QoS requirements and maximizes system throughput was proposed. Secondly, after the scheduling, a non-cooperative game control algorithm was proposed based on improved cost function. The results show that compared with the existing algorithms, the proposed algorithm performs better in satisfying user＇s QoS requirements and user fairness, and also has higher system throughput.
