Japanese Patent JP4772148

B2

A base station device includes: a random access identification information storage that stores random access identification information and mobile station device identification information correlated with the random access identification information, the random access identification information being allocated by the base station device to the mobile station device, and the mobile station device identification information identifying the mobile station device; a random access receiver that receives random access identification information transmitted by the mobile station device performing random access; a scheduler that, if the random access identification information received is stored in the random access identification information storage while being correlated with the mobile station device identification information, determines whether to transmit random access response information that is a response to the random access corresponding to the random access identification information received by using the mobile station device identification information, or by using identification information having not been allocated to a specific mobile station device, the identification information being allocated for transmitting the response to the random access; and a transmitter that allocates and transmits the random access response information based on the determination by the scheduler.
