5G多频协同技术研究

与4G时代网络能力主要以下行为主不同,5G时代的业务特性正在发生变化。随着直播业务的高清化,无线视频监控类应用等一系列5G基础业务的兴起,对上行能力提出了更高的要求。本文结合中国移动5G频率资源现状,简述基于5G R16版本的几种多频协同技术,深入分析多频协同技术的网络性能及组网中面临的问题,并提出在实际组网中多频协同技术的选择策略建议,充分发挥各频段的优势,取长补短增强上行能力,最大化资源效率,打造差异化的竞争优势。

Research on 5G multi-frequency coordination technology of China Mobile

Different from 4G network capability based on downlink, the business characteristics in the 5G are changing. With the high-definition of live broadcast business and the rise of a series of 5G basic businesses such as wireless video monitoring applications, higher requirements are put forward for uplink capabilities. Based on the current status of China Mobile"s 5G frequency resources, this paper briefly describes several multi-frequency coordination technologies based on the 5G R16 version, analyzes the network performance and the problems in the network. This paper also proposes strategy recommendations for selecting multi-frequency coordination technologies in actual networking, to give the advantages of each frequency band to enhance uplink capacities, maximize resource efficiency, and create differentiated competitive advantages.
