A method of receiving a downlink signal from a plurality of cells at a user equipment in a cell cooperative wireless communication system is described. Downlink control information including downlink scheduling information for a serving cell and one or more coordinating cells at the user equipment from the serving cell is received. Whether the downlink control information includes one resource assignment field or at least two assignment fields is monitored. Depending upon monitoring, a downlink data signal from the serving cell and the one or more coordinating cells using the downlink scheduling information is received. The downlink control information for the downlink data signal is received through one Physical Downlink Control Channel. The downlink data signal received from each of the serving cell and the one or more coordinating cells is either received on an identical frequency band or a partially overlapped frequency band.
