论文摘要
我们考虑一个具有基站（BS）和多个移动/固定用户的系统。 BS使用毫米波（MMWaves）进行数据传输，因此需要在最终用户的方向上对齐光束。这个想法是利用常规的用户位置估计，这有助于对多个用户进行准确的光束对齐，并为机会主义的MMWave调度程序铺平了道路。我们提出了一种在线算法，该算法使用双重机会和公平的调度程序在每个插槽中分配数据以及位置更高的频道。在此方面，优化了众所周知的alpha-fair实用性目标功能，进一步依赖于位置信息的年龄。我们通过将其与先前提出的MMWAVE计划进行比较来说明机会调度程序的优势；这些调度程序在每个插槽中选择一个用户，并仅在准确的光束对齐后才启动数据传输。我们还讨论了在此类方案中引入公平性的两种方法，两者都表现不如拟议的基于年龄的机会调度程序。
We consider a system with a Base Station (BS) and multiple mobile/stationary users. BS uses millimeter waves (mmWaves) for data transmission and hence needs to align beams in the directions of the end-users. The idea is to avail regular user-position estimates, which help in accurate beam alignment towards multiple users, paving way for opportunistic mmWave schedulers. We propose an online algorithm that uses a dual opportunistic and fair scheduler to allocate data as well as position-update channels, in each slot. Towards this, well-known alpha-fair objective functions of utilities of various users, which further depend upon the age of position-information, are optimized. We illustrate the advantages of the opportunistic scheduler, by comparing it with the previously proposed mmWave schemes; these schedulers choose one user in each slot and start data transmission only after accurate beam alignment. We also discuss two ways of introducing fairness in such schemes, both of which perform inferior to the proposed age-based opportunistic scheduler.
