中继无线帧定时调整的方法、设备和系统技术方案

本发明专利技术实施例公开了一种中继无线帧定时调整的方法、系统和设备，该方法包括：基站向中继发送帧定时调整命令；所述基站向所述中继发送控制信令，指示所述中继根据所述帧定时调整命令携带的时间延迟调整中继回程链路的下行链路和／或接入链路的上行和／或下行。本发明专利技术中，基站向中继发送帧定时调整命令，通过控制信令指示中继根据帧定时调整命令携带的时间延迟调整中继回程链路的下行链路和／或接入链路的上行和／或下行，从而可以使中继在接入链路内的发送和接收都和ｅＮＢ的发送和接收同步，能够在ｅＮＢ和中继之间实现ＭＢＭＳ业务。

Method, apparatus and system for adjusting relay radio frame timing

The embodiment of the invention discloses a method and system for equipment cases, a relay wireless frame timing adjustment, the method comprises: a base station to relay transmission frame timing adjustment command; the base station to the relay control signaling, indicating the relay according to the frame timing adjustment command with the time delay adjustment relay backhaul link the downlink and / or access links upstream and / or downstream. In the invention, the base station to relay transmission frame timing adjustment command, by controlling the signalling relay according to the uplink downlink frame timing adjustment command carried by the time delay adjustment relay backhaul link and / or access link and / or down, which can make the relay at the access link in sending and receiving and sending and receiving eNB simultaneously, MBMS business can be achieved between eNB and relay.
