Patent ID: 8670386

Claim:
A method for implementing transmission of a backhaul link control channel in a relay system, comprising: sending, by an eNodeB, initial information of the backhaul link control channel to each relay served by the eNodeB; completing an initial configuration of the backhaul link control channel between the eNodeB and each relay, wherein the initial configuration comprises configuring a dedicated control channel resource region for each relay; and performing, by the eNodeB and each relay, transmission and updating of control information of the backhaul link through the dedicated control channel resource region; wherein the initial information of the backhaul link control channel comprises: configuration information of a multicast broadcast single frequency network MBSFN subframe used by the relay; a relay physical cell identity used by the relay, wherein the relay physical cell identity used by the relay is allocated by the eNodeB to ensure that a reference symbol sent by the relay and a reference symbol sent by the eNodeB are orthogonal at a frequency domain position; and position information of the dedicated control channel resource region used by the relay, a size of the backhaul link control channel, and information about a transmission format of the control channel.
