论文摘要
我们为毫米波（MMWave）的新型用户设备（UE）调度框架进行了大规模多用途（MU）多输入多输出（MIMO）无线系统。我们的框架确定了应在给定时间插槽中同时发送的UE（子）集，该集合通过使用向前的拆分来求解非convex优化问题，从而在给定的时间段中同时发送。我们的UE调度框架是灵活的，因为它（i）支持各种成本功能，包括均值均值均值错误和总和速率，以及（ii）对UES应占据的最小和最大资源的精确控制。我们使用商用射线跟踪器生成的现实MMWave通道向量证明了框架的功效。我们表明，我们的UE调度程序的表现优于一系列现有的调度方法，并紧密接触了详尽搜索的性能。
We propose a novel user equipment (UE) scheduling framework for millimeter-wave (mmWave) massive multiuser (MU) multiple-input multiple-output (MIMO) wireless systems. Our framework determines (sub)sets of UEs that should transmit simultaneously in a given time slot by approximately solving a nonconvex optimization problem using forward-backward splitting. Our UE scheduling framework is flexible in the sense that it (i) supports a variety of cost functions, including post-equalization mean square error and sum rate, and (ii) enables precise control over the minimum and maximum number of resources the UEs should occupy. We demonstrate the efficacy of our framework using realistic mmWave channel vectors generated with a commercial ray-tracer. We show that our UE scheduler outperforms a range of existing scheduling methods and closely approaches the performance of an exhaustive search.
