论文摘要
智能中继器（SR）可以潜在地增强毫米波（MMWave）无线通信的覆盖范围。但是，现有的两面板SR的角度覆盖范围太限制了，无法使SR成为真正具有成本效益的MMWave范围扩展器。本文提出了三个部门高级SR（ASR）的使用，以扩大有关常规SR的角度覆盖。我们在下行链路多载波通信系统中为ASR提出了多用户预编码器优化，以最大化服务的用户设备（UES）数量，同时保证对频率和时间频率资源的限制。数值结果表明，在累积光谱效率和已服务的UES数量方面，ASR的好处（平均因子2提高），改变了系统参数。
Smart Repeaters (SR) can potentially enhance the coverage in Millimeter-wave (mmWave) wireless communications. However, the angular coverage of the existing two-panel SR is too limited to make the SR a truly cost-effective mmWave range extender. This paper proposes the usage of a tri-sectoral Advanced SR (ASR) to extend the angular coverage with respect to conventional SR. We propose a multi-user precoder optimization for ASR in a downlink multi-carrier communication system to maximize the number of served User Equipments (UEs) while guaranteeing constraints on per-UE rate and time-frequency resources. Numerical results show the benefits of the ASR against conventional SR in terms of both cumulative spectral efficiency and number of served UEs (both improved by an average factor 2), varying the system parameters.
