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

摘要

A disclosed base station includes a management unit for managing frequency blocks, a scheduler for generating scheduling information for each of the frequency blocks to allocate one or more resource blocks to each of selected communication terminals having good channel conditions, a channel generating unit for generating control channels including the scheduling information for the respective frequency blocks, a multiplexing unit for frequency-multiplexing the control channels in a system frequency band, and a transmitting unit for transmitting the frequency-multiplexed control channels according to a multicarrier scheme. The control channels transmitted by the base station includes a general control channel to be decoded by communication terminals in general and specific control channels to be decoded by selected communication terminals that are allocated one or more resource blocks.
