Abstract

5G and beyond 5G is an emerging technology used to overcome the increasing mobile traffic triggered by new services. Utilization of millimeter wave is one of the key technologies for 5G NR to address radio resource shortage, especially below the 6-GHz band. However, compared with <6-GHz bands, millimeter wave is efficiently blocked by structures. Therefore, adjustments are required to make radio links line-of-sight. Moreover, the spatial user distribution is not uniform; there are hot spots, and the spatial user distribution changes with time. In this paper, we focus on millimeter-wave distributed antenna systems (mmWave DAS), which solve the issues associated with radio propagation of millimeter wave, and developed an algorithm to solve the mobile traffic imbalance between cells caused by nonuniform user distribution. The proposed algorithm improves the fairness of the system throughput using a system-level simulation.
5G毫米波分布式天线系统负载均衡技术
5G及以上5G是一项新兴技术,用于克服新业务引发的移动流量增长。毫米波的利用是5G NR解决无线电资源短缺的关键技术之一,特别是在6ghz以下频段。然而,与< 6ghz频段相比,毫米波被结构有效地阻挡。因此,需要进行调整,使无线电链路在视线范围内。用户空间分布不均匀;存在热点,用户空间分布随时间变化。本文主要研究毫米波分布式天线系统(mmWave DAS),该系统解决了毫米波无线电传播的相关问题,并开发了一种算法来解决因用户分布不均匀而导致的小区间移动业务不平衡问题。通过系统级仿真,提高了系统吞吐量的公平性。
