提高LTE中继蜂窝系统吞吐量的新方案
New scheme for improving throughput in LTE relay cellular system
摘要
Abstract
The Relay can expand the coverage of the base station and improve the throughput of the edge users,but it may generate interference to the direct link users and destroy the fairness of the cellular users at the same time.To solve this problem,this paper presents a new resource allocation (NRA) scheme.Under the premise of guaranteeing the quality of service for the direct link users and the relay link users,the optimal direct link is selected for access link to share the resources,and then the resources are allocated in turn to the backhaul links and the direct links.Simulation results show that the NRA scheme can effectively improve the fairness and the throughput of the whole cellular system.关键词
