The embodiment of the invention discloses a system and a device for the backhaul link control signaling and signal detection method, and relates to the field of wireless communication, to save the base station through the relay backhaul link on the physical downlink control channel R PDCCH sending control signaling occupied time-frequency resources and reduce the complexity of the relay node detection RPDCCH. In the invention, the base station according to the corresponding relationship between the control signaling and RPDCCH resource sub area preset, determining a plurality of sub regional resources and regional resources RPDCCH occupied contains and to send control signal corresponding to the RPDCCH sub regional resources; using time-frequency resources RPDCCH resources identified in the sub region to be sent to a relay node send control signal; relay node obtains the location information of the R PDCCH resource sub region, according to the position information to detect sending control signaling in the R - PDCCH resources within the region. The invention can effectively save the time frequency resources occupied by the base station by transmitting the control signaling through the R PDCCH, and reduce the complexity of the relay node detecting R PDCCH.
