Abstract:
1. A method for scheduling in a carrier aggregation system, the method comprising: transmitting information for indicating a plurality of secondary cells to be scheduled through a joint coded control channel by using a higher layer signal; transmitting a separate coded control channel for scheduling a primary cell; and transmitting one joint coded control channel for scheduling the plurality of secondary cells, wherein the separate coded control channel is a control channel for scheduling one data channel transmitted through the primary cell, and the joint coded control channel is a control channel for scheduling a plurality of data channels transmitted through the plurality of secondary cells, and wherein if a semi-persistent scheduling (SPS) serving cell for performing semi-persistent scheduling exists among the plurality of secondary cells, a release of semi-persistent scheduling of the SPS serving cell is indicated by combining control information for scheduling the SPS serving cell in a joint coded physical downlink control channel (PDCCH).
