摘要
边缘区域用户的服务质量和资源利用率的提升是D2D辅助中继技术的研究重点。研究提出了应用于5G网络的高性能SL-DRX方案,该方案引入PSCCH计数器和业务量阈值改进原有网络通信方案,以解决SLDRXInactivityTimer超时问题。长短周期切换结果验证,研究所提出的策略一相比较于策略二具有更好的性能,策略一因发送产生的最大能耗、最大监听成功率、最大吞吐量分别为4863unit、100%、3.62×104bps。SL-DRX方案一和SL-DRX方案二在PSCCH计数器阈值分别为1~8、1~7区间内拥有更佳的性能。研究所提出的高能效SLDRX方案对D2D中继技术进行了创新性地改进。
The improvement of service quality and resource utilization of users in edge areas is the research focus of D2D auxiliary relay technology.A high-performance sl-drx scheme applied to 5g network is proposed.The scheme introduces pscch counter and traffic threshold to improve the original network communication scheme to solve the sldrx inactivitytimer timeout problem.The results of long and short cycle handoff verify that the proposed scheme a has better performance than scheme B.the maximum energy consumption,maximum listening success rate and maximum throughput of scheme a due to transmission are 4863unit,100% and 3.62 respectively ×104bps.Scheme 1 and scheme 2 have better performance in the range of 1~8 and 1~7 respectively.The energy-efficient sl-drx scheme proposed by the research institute innovatively improves the D2D relay technology.
