BASE STATION, COMMUNICATION TERMINAL, TRANSMISSION METHOD AND RECEPTION METHOD.

摘要

A base station comprises a means for managing frequency blocks, a means for determining scheduling information for each frequency block to allocate one or more resource blocks to communication terminals in a good channel state, a means for creating a control channel including the scheduling information for each frequency block and a means for frequency-multiplexing the control channels within a system frequency band and transmitting them on a multi-carrier basis. The base station also transmits the control channels divided into nonspecific control channels decoded by nonspecific communication terminals and the specific control channels decoded by the communication terminals to which the one or more resource blocks are allocated.
