Claim Text:
1. A method for receiving control information about a coordinated multi-point (CoMP) set by a user equipment from a serving transmission point in a carrier aggregation based wireless communication system, the CoMP set including a primary cell and a secondary cell, the method comprising: receiving information indicating control information size through higher layer signaling; and monitoring a plurality of control channel candidates for each cell of the CoMP set on the primary cell of the CoMP set and detecting the control information, wherein, when the control information corresponds to a transmission mode (TM) dedicated downlink control information (DCI) format, the plurality of control channel candidates for each cell of the CoMP set are determined to have a same information size as the control information size received through the higher layer signaling, and wherein, when the control information corresponds to a TM common DCI format, the plurality of control channel candidates for each cell of the CoMP set are determined to have a same information size as a DCI format size configured in the primary cell.
