摘要： A random access instructed by a base station apparatus and having a small delay is enabled in Advanced-EUTRA system. Upon detection of control data in any one of a plurality of component carriers, component carrier information, a preamble number, and random access channel information are extracted from the control data, and if the extracted information indicates dedicated preamble transmission, a random access channel position to be used is selected from information on random access of a component carrier specified in the component carrier information and the random access channel information, a random access preamble is generated from the information on random access and the dedicated preamble number, and the random access preamble is transmitted at the random access channel position.

摘要： Contention based uplink transmission is efficiently performed. A scheduling unit selects, when uplink grant includes C-RNTI allocated to its device, the whole of radio resources indicated by this uplink grant. When uplink grant includes CB-RNTI, the scheduling unit randomly selects one radio resource from multiple radio resources indicated by this uplink grant. The scheduling unit generates control information for controlling a transmission unit so that PUSCH is multiplexed on the selected radio resource, and outputs it to a control unit. When blind decoding of multiple uplink grants including CB-RNTI has successfully been performed, the scheduling unit randomly selects one radio resource from the whole of multiple radio resources indicated by multiple uplink grants. The scheduling unit generates control information for controlling the transmission unit so that PUSCH is multiplexed on the selected radio resource, and outputs it to the control unit.
