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.

摘要： A radio communication system includes a base station device and a plurality of mobile station devices which radio-communicate with the base station device. The base station device allocates random access signal identifiers for identifying random access signals to the mobile station devices and decides an allocation period for each of the random access signal identifiers used by the mobile base stations. During the allocation period, each of the mobile station devices transmits a random access signal corresponding to the allocated random access signal identifier. Thus, it is possible to suppress a delay until the random access procedure using a dedicated preamble is complete.
