    • A method, system and device for transmitting and detecting control signaling in a backhaul link are disclosed in the present application, and the application relating to the wireless communication field is used for saving time-frequency resources occupied by a base station for transmitting the control signaling on a Relay Physical Downlink Control Channel (R-PDCCH) of the backhaul link and reducing the complexity of the R-PDCCH detection by a relay node. In the present application, the base station, according to the preset correspondence between the control signaling and the R-PDCCH resource sub-regions, determines the R-PDCCH resource sub-region corresponding to the control signaling to be transmitted among a plurality of resource sub-regions included in the resource region occupied by the R-PDCCH; the control signaling to be transmitted is transmitted to the relay node by using the time-frequency resources in the determined R-PDCCH resource sub-region; the relay node acquires the location information of the R-PDCCH resource sub-region and detects the control signaling to be transmitted in the R-PDCCH resource sub-region according to the location information. With the present application, the time-frequency resources occupied by the base station for transmitting the control signaling on the R-PDCCH are saved and the complexity of the R-PDCCH detection by the relay node is reduced.
    • 在本申请中公开了用于在回程链路中发送和检测控制信令的方法,系统和设备,并且与无线通信领域有关的应用被用于保存由基站占用的用于发送控制信令的时间 - 频率资源 在回程链路的中继物理下行链路控制信道(R-PDCCH)上,并且降低由中继节点进行的R-PDCCH检测的复杂度。 在本申请中,基站根据控制信令与R-PDCCH资源子区域的预设对应关系,确定与多个资源之间要发送的控制信令对应的R-PDCCH资源子区域 由R-PDCCH占用的资源区域中包含的子区域; 要发送的控制信令通过使用所确定的R-PDCCH资源子区域中的时间 - 频率资源发送到中继节点; 中继节点获取R-PDCCH资源子区域的位置信息,并根据位置信息检测在R-PDCCH资源子区域中发送的控制信令。 在本申请中,保存了用于在R-PDCCH上发送控制信令的基站占用的时间 - 频率资源,并且减少了由中继节点进行的R-PDCCH检测的复杂度。
