A terminal device free of interference between an RACH and a PUSCH or the like even when a base station device with a large coverage is installed. In the device, a configuration number extraction unit (103) extracts a configuration number from a BCH received by a BCH reception unit (102). A control unit (104) determines the corresponding RACH format (the necessity of repetition, the CP length TCP, the second preamble length TPRE2, and the GT length TGT) according to the configuration number, notifies a repetition unit (109) of the result of the judgment of necessity of repetition, notifies the repetition unit (109) of the second preamble length TPRE2, notifies a CP addition unit (110) of the CP length TCP, and notifies a GT addition unit (112) of the GT length TGT. When the repetition unit (109) receives the notification of performing the repetition, it performs the repetition according to the second preamble length received from a TPRE2 determination section (154). The CP addition unit (110) produces a CP according to the CP length received from a TCP determination section (155).
