Method and device for allocating control channel candidates

摘要

Provided are a method and device for allocating control channel candidates, which relate to the field of communications and can allocate control channel candidates of different aggregation levels to K ePDCCH sets, so as to reduce the complexity for a UE to perform blind detection. The method comprises: determining K sets used for transmitting control channels, wherein each set of the K sets comprises at least one physical resource block pair; and according to the aggregation levels supported by the control channels to be transmitted, the number of control channel candidates corresponding to each of the aggregation levels, and at least one of the K sets for transmitting the control channels and the type of the sets, allocating the control channel candidates of each aggregation level to at least one set of the K sets.
