Effective method for transmitting control information during the combination of multiple carriers for wideband support

摘要

The present invention relates to wideband wireless access system, and more particularly to an effective method for transmitting control information during the combination of multiple carriers. As one embodiment of the present invention, there is provided a method by which a base station allocates a carrier to a terminal in a wideband wireless access system supporting multiple carriers, the method comprising: transmitting, to the terminal, a terminal specific or terminal group specific carrier allocation information that includes information about at least one of control information and data; and transmitting, to the terminal, a carrier combination control information that includes information about a change in the at least one candidate carrier available.

1. A method for transmitting carrier assigning information by a base station in a wireless communication system supporting multiple carriers, the method comprising:
transmitting user equipment (UE)-specific or user equipment (UE)-group-specific carrier assignment information to a user equipment, the UE-specific or UE-group-specific carrier assignment information including information on at least one available candidate carrier, the at least one available candidate carrier being assigned by the base station based on capability of the UE; transmitting a physical downlink control channel (PDCCH) via a primary carrier, the PDCCH comprising a carrier indicator, the carrier indicator indicating a carrier on which a physical downlink shared channel (PDSCH) or a physical uplink shared channel (PUSCH) is transmitted; transmitting the PDSCH via the indicated carrier or receiving the PUSCH via the indicated carrier based upon the PDCCH, the indicated carrier being the primary carrier or an available carrier of the at least one available candidate carrier; and transmitting carrier aggregation control information to the user equipment, wherein the carrier aggregation control information includes configuration change information or status change information of the at least one available candidate carrier.
