5G室内场景多通道联合收发技术性能与关键问题

Performance and key issues of 5G multi-channel joint transceiver technology

随着数据业务的爆发式增长,室内覆盖成为5G时代的重要场景,部署5G室分系统是解决5G室内覆盖问题的重要手段之一。室分系统部署面临两大场景:新建场景与改造场景。针对室内改造场景,如何保护投资、低成本建设5G网络,同时让用户获得5G多流MIMO体验是目前最关注的问题点。介绍了一种基于多通道收发技术的5G网络创新室分升级改造方案。该方案通过增加竖井线缆、合路器、耦合器等方式,在不改变平层传统室分网络结构的前提下,能够快速在单路馈线场景下实现2流、双路馈线场景下实现4流效果,激发了传统室分网络的5G潜能,从而实现低成本、高效的5G创新室分解决方案。

With the explosive growth of data services, 5G indoor coverage has become the top priority. Deploying 5G indoor subsystem is one of the important means to solve the problem of 5G indoor coverage. An upgrading scheme of 5G indoor subsystem based on multi-channel transceiver technology was introduced. This scheme can achieve double flow with single feeder and four flow with double feeder, and improve the performance of 5G with low cost. The main construction of the scheme includes: adding shaft cable, adding combiner, adding coupler, without changing the flat floor network structure.
