摘要
在TD-LTE上行系统中,有效地资源分配对系统性能有着决定性作用,仅通过信道质量进行资源分配的分配算法没有考虑UE的数据业务,会造成实际资源利用率不高。采用Kuhn-Munkres算法与RME算法相结合,提出一种TD-LTE系统上行资源分配新算法,有效解决了RME算法中存在的深衰落问题。该算法根据信道质量与实际的UE业务量共同决定PRB资源,并进行TD-LTE上行系统资源分配。实验结果表明,所提出算法不仅可以保证在一定的数据传输速率上提高实际的资源利用率,而且还可以提高系统的平均吞吐量。
In the TD-LTE uplink system,efficient allocation of resources has a decisive role on the performance of the system,without considering the UE data service only through the channel quality allocation algorithm for resource allocation,will cause the actual resource utilization rate is not high.By combining Kuhn-Munkres algorithm with RME algorithm,a new algorithm for uplink resource allocation in TD-LTE systems is proposed,which effectively solves the problem of deep fading in RME algorithm.The algorithm determines the PRB resource according to the channel quality and the actual UE traffic,and carries out the TD-LTE uplink system resource allocation.The results show that he proposed algorithm can not only improve the actual resource utilization,but also improve the average throughput of the system on the basis of ensuring a certain data rate.
