摘要
针对异构网络部署中继站的场景,对现有全双工中继站组网方案进行了简要介绍,设计了一种自适应双工中继站的组网方案。根据最大速率准则,该方案可以自适应地在相应资源块中布置合适的中继站和用户,以及决策每个时隙的中继双工模式。对系统在不同双工模式中继站情形下的吞吐量性能进行了仿真,仿真结果表明这种自适应双工方案可以有效提升吞吐量性能。
Aiming at the scenario of deploying relay station in heterogeneous network,this paper introduces the networking scheme of the existing full-duplex relay station,and designs the adaptive networking scheme. According to the maximum rate criterion,the scheme can be used to arrange appropriate relay stations and users in corresponding resource blocks,as well as to decide the relay duplex mode of each time slot.The throughput performance of the system in different dual-mode relay station is simulated.The simulation results show that this adaptive duplex scheme can effectively improve throughput performance.
