论文摘要
多连通性正在成为一种有前途的解决方案,可为毫米波频率范围提供可靠的通信和无缝连接性。由于在如此高频率下的阻塞灵敏度,与多个单元格的连通性可以大大提高网络性能,从而在吞吐量和可靠性方面。但是,链接调度效率低下,即连接的过度和底层不足可能会导致高干扰和能源消耗,也可以导致用户的服务质量(QOS)要求不满意。在这项工作中,我们提出了一个基于学习的解决方案,该解决方案能够学习,然后预测最佳链接计划,以满足用户的QoS要求,同时避免通信中断。此外,我们将所提出的方法与两种基本方法和精灵辅助链路计划进行比较,该计划具有完美的渠道知识。我们表明,基于学习的解决方案方法可以接近最佳,并优于基线方法。
Multi-connectivity is emerging as a promising solution to provide reliable communications and seamless connectivity for the millimeter-wave frequency range. Due to the blockage sensitivity at such high frequencies, connectivity with multiple cells can drastically increase the network performance in terms of throughput and reliability. However, an inefficient link scheduling, i.e., over and under-provisioning of connections, can lead either to high interference and energy consumption or to unsatisfied user's quality of service (QoS) requirements. In this work, we present a learning-based solution that is able to learn and then to predict the optimal link scheduling to satisfy users' QoS requirements while avoiding communication interruptions. Moreover, we compare the proposed approach with two base line methods and the genie-aided link scheduling that assumes perfect channel knowledge. We show that the learning-based solution approaches the optimum and outperforms the base line methods.
