论文摘要
毫米波（MMWave）将在不久的将来面对巨大数据速率的需求中，将作为5G候选人发挥重要作用。常规的MMWave标准IEEE 802.11AD认为仅在无线局域网（WLAN）中建立一个MMWave链接以提供多GBPS数据速率。但是，MMWave有一个脆弱的渠道，它阻碍了它提供此类速度。因此，有必要通过在5G网络中部署多个MMWave访问点（AP）来同时建立多个MMWave链接。不幸的是，应用常规标准而无需对MMWave并发传输进行任何修改会阻碍MMWave AP选择最佳MMMWAVE并发链接。因为IEEE 802.11AD标准使用具有最大接收功率的链接将用户设备（UES）关联到MMWave AP，而无需考虑同时链接之间的相互干扰。在本文中，制定了建立最佳MMWave并发传输链接的联合比例公平计划（JPFS）优化问题。并且，为了找到解决此非多项式（NP）时间问题的解决方案，我们使用详尽的搜索（ES）方案。数值模拟证明了使用ES方案改善系统性能的有效性。
Millimeter wave (mmWave) will play a significant role as a 5G candidate in facing the growing demand of enormous data rate in the near future. The conventional mmWave standard, IEEE 802.11ad, considers establishing only one mmWave link in wireless local area network (WLAN) to provide multi Gbps data rate. But, mmWave has a tenuous channel which hinders it from providing such rate. Hence, it's necessary to establish multiple mmWave links simultaneously by deploying a multiple number of mmWave access points (APs) in 5G networks. Unfortunately, applying conventional standard without any modifications for mmWave concurrent transmission impedes mmWave APs from selecting optimum mmWave concurrent links. Because IEEE 802.11ad standard associates the user equipment (UEs) to mmWave APs using the link that has the maximum received power without considering mutual interference between simultaneous links. In this paper, a joint proportional fairness scheduling (JPFS) optimization problem for establishing optimum mmWave concurrent transmission links is formulated. And, to find a solution to this non-polynomial (NP) time problem, we use exhaustive search (ES) scheme. Numerical simulation proves the effectiveness of using the ES scheme to improve the system performance.
