LTE-A中继系统中基于吞吐量和公平性博弈的RRM策略

RRM strategy based on throughput and fairness in LTE-A relay system

为解决LTE-A系统中继场景下系统吞吐量和用户公平性的均衡问题,提出用户SINR分散度并以此作为公平性的主要参数,改善小区中心用户和边缘用户的公平性。对小区吞吐量和用户公平性进行博弈建模,基于博弈结果提出资源分配的目标均衡算法。仿真结果表明,提出的目标均衡算法将吞吐量、公平性和博弈论结合起来,在保证系统吞吐量的情况下提高了用户公平性,使系统资源利用更加有效。

For the imbalance between the system throughput and the user fairness in the LTE-A system with relay ,the user SINR dispersion degree was proposed as the main parameter of the fairness ,and the fairness of center users and edge users was improved significantly .The game model for the system throughput and the user fairness was established and the balanced aim al-location algorithm for the allocation of resources was proposed based on the game results .Simulation results show that the pro-posed balanced aim allocation algorithm which combines the throughput ,the user fairness and the game theory improves the user fairness on the premise of assuring the system throughput ,making the system resource allocation more efficient .
