Abstract
The present invention discloses a method which includes: allocating, by an eNodeB, a dedicated resource region for a relay served by the eNodeB; calculating, by the eNodeB, a control channel of the relay; configuring, by the eNodeB according to the resource region allocated for the relay and the acquired control channel of the relay, the control channel of the relay in the resource region corresponding to the relay; and detecting, by the relay, control information sent by the eNodeB in the corresponding resource region allocated by the eNodeB for the relay. The present invention solves the transmission problem of a backhaul link control channel in an LTE-A relay system, so that a relay can receive control information sent by the eNodeB within a wider scope and that the complexity of blind detection of the relay is decreased.
