LTE-A系统载波聚合下基于贪心算法的资源管理
Resource Management Based on Greedy Algorithm for Carrier Aggregation in LTE-A System
摘要
Abstract
To better balance system throughput and user fairness of LTE-A systems,a resource management based on greedy algorithm is proposed.The Channel State Information(CSI) information reported by the client is fully utilized to reduce the performance impact of carrier aggregation by channel variation,and the greedy algorithm is adopted to solve the NP-hard problem of resource allocation.In scheduling process,the weight factor is redesigned by using occupied resource blocks and average rate to guarantee the different Quality of Service(QoS) requirements of all kinds of users.Simulation results show that compared with LL + PF algorithms,the proposed algorithm has better performance both in user fairness and system throughput.关键词
