    Abstract: A disclosed base station employs a multicarrier scheme and performs frequency scheduling in a frequency band including multiple resource blocks each including one or more subcarriers. The base station includes a frequency scheduler for receiving channel condition information from communication terminals and generating scheduling information to allocate resource blocks to selected communication terminals having good channel conditions based on the channel condition information; a coding and modulation unit for encoding and modulating control channels including a general control channel to be decoded by the communication terminals and specific control channels to be decoded by the selected communication terminals; a multiplexing unit for time-division-multiplexing the general control channel and the specific control channels according to the scheduling information; and a transmitting unit for transmitting the time-division-multiplexed signal according to the multicarrier scheme. The coding and modulation unit encodes the general control channel separately for the respective communication terminals.

    Abstract: PROBLEM TO BE SOLVED: To minimize the overhead for signalling of frequency hopping information between devices of a communication system that uses Frequency Division Multiple Access (FDMA) techniques.SOLUTION: There is provided a communications system in which user devices used in the uplink of the E-UTRA communications scheme communicate with an associated base station 5. The user devices employ frequency hopping techniques to provide frequency diversity in their communications with the base station. Techniques are provided for reducing collisions between the communications from the different user devices and for the efficient signalling of data defining the frequency hopping sequence to use.
