摘要

射频直放站在 2G、3G 和 4G 的部署均用于增强蜂窝网络的覆盖。虽然传统射频直放站提供了一种经济高效的方法用于扩展网络覆盖范围，但其仅能依照固定配置对信号执行放大和转发操作，无法依照网络调度和控制对该行为进行灵活调整。介绍了 5G 演进中的网络控制直放站，作为对传统射频直放站的增强，网络控制直放站具有从网络侧接收针对直放站控制信息的能力，并依据此信息以更有效的方式执行其放大和转发操作，包括实现信号在空间域的定向增强、直放站的动态使能和简化的网络集成。

Abstract

Radio frequency (RF) repeaters have been deployed in 2G

3G and 4G to improve the coverage of cellular system.While it is treated as a cost effective solution to extend the network coverage

conventional RF repeaters simply perform amplify-and-forward operation based on the set-up without the capability of doing flexible adjustments based on control and scheduling indication from network.An overview on the new study item in 5G-Advanced was given

i.e.network-controlled repeater.As an enhancement over conventional RF repeaters

network-contrdled repeater will enable the repeater to receive and process repeater control information from the network and perform its amplify-and-forward operation in a more efficient manner including the directive forwarding of the signal

dynamic on-/off of transmissions and receptions

and simplified network integration.
