    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.
