    摘要： A radio environment acquirer acquires a radio environment condition of radio communication with a subordinate mobile station. A transmitter transmits, to the mobile station, information notifying a signal which is selected from among multiple signal groups and which is to be transmitted in a transmission area of a random access signal, and a notification of a period over which transmission of the signal as the random access signal is permitted. The period is variable in accordance with the radio environment condition acquired by the radio environment acquirer.

    摘要： A wireless base station apparatus includes a reporting unit which reports information on a first transmission area that allows transmission of a random access signal. Accordingly, the first transmission area is wholly reported to mobile station apparatuses within an area of the wireless base station apparatus. That is, both a mobile station apparatus in a non-handover state and a mobile station apparatus in a handover state receive the first transmission area information (report information) and use the first transmission area as a transmission area for transmitting a random access signal to the wireless base station apparatus. The wireless base station apparatus also has a notifying unit which notifies a second transmission area to a mobile station apparatus in a handover state, the second transmission area being different from the first transmission area reported by the reporting unit of the handover-destination wireless base station apparatus.
