Title
(EN) INITIAL ACCESS AND RADIO RESOURCE MANAGEMENT FOR INTEGRATED ACCESS AND BACKHAUL (IAB) WIRELESS NETWORKS
(ZH) 集成的接入和回程(IAB)无线网络的初始接入和无线电资源管理
Abstract
(EN)
Establishment of integrated links comprising integrated wireless backhaul communications links and access communications links is facilitated by transmitting multiplexed sync signals to enable synchronization between the relay transmission point devices, and using a random access channel procedure to complete the establishment. The integrated wireless backhaul communications links and access communications links can be maintained by measuring channel characteristics of the backhaul communications links using a measurement reference signal.

(ZH)
通过发送复用的同步信号以使得能够在中继传输点设备之间同步并使用随机接入信道过程来完成建立,来促进包括集成的无线回程通信链路和接入通信链路的集成链路的建立。可以通过使用测量参考信号测量回程通信链路的信道特性来维护集成的无线回程通信链路和接入通信链路。
