摘要翻译：
毫米波（mmWave）通信有望在下一代蜂窝网络中发挥重要作用，以解决传统无线载波带宽不足的问题。在mmWave massive MIMO（m-MIMO）通信中，利用边信息加速波束选择是一种潜在的方法。然而，在实践中，此类信息并不是没有错误的，从而导致性能下降。在多用户情况下，错误的波束选择可能导致基站(BS)侧不可减少的用户间干扰。本文研究了多用户mmWave上行链路中位置辅助预编码器的设计。假设存在直接器件到器件(D2D)链路，我们提出了一种分散协调机制，用于鲁棒快速波束选择。该算法允许在BS侧对干扰的改进处理，并进而导致更大的频谱效率。

英文摘要：
  Millimeter wave (mmWave) communication is expected to play an important role in next generation cellular networks, aiming to cope with the bandwidth shortage affecting conventional wireless carriers. Using side-information has been proposed as a potential approach to accelerate beam selection in mmWave massive MIMO (m-MIMO) communications. However, in practice, such information is not error-free, leading to performance degradation. In the multi-user case, a wrong beam choice might result in irreducible inter-user interference at the base station (BS) side. In this paper, we consider location-aided precoder design in a mmWave uplink scenario with multiple users (UEs). Assuming the existence of direct device-to-device (D2D) links, we propose a decentralized coordination mechanism for robust fast beam selection. The algorithm allows for improved treatment of interference at the BS side and in turn leads to greater spectral efficiencies.
