摘要：
A base station device includes: a re-synchronization factor detector that detects an uplink re-synchronization factor of a mobile station device; a data controller that generates, when the re-synchronization factor detector detects the uplink re-synchronization factor, data in which information indicative of an uplink synchronization request addressed to the mobile station device is set to a region on a radio frame to which parameters to be used for synchronous communication with the mobile station device are to be set; and a transmitter that transmits data generated by the data controller.
