Abstract:
A disclosed base station apparatus in a mobile communication system includes a receiving unit receiving a random access channel transmitted from a mobile station apparatus, an acquisition unit acquiring random access channel quality based on a measurement of the received random access channel or a report from the mobile station apparatus, a calculation unit calculating random access channel parameters based on the acquired random access channel quality, and a broadcast unit broadcasting the calculated random access channel parameters to all the mobile stations within a coverage area of the base station.
