Abstract
A mobile radio communication system for communicating between a base station and a mobile station by means of frames, each frame including a header and data. The mobile station includes a transmission number provider which provides a first transmission number to a first frame to be transmitted to the base station, and a transmission number extractor which extracts the first transmission number indicated in a header pattern of a second frame transmitted by the base station. The base station includes a reception number detector which detects the first transmission number included in the first frame transmitted by the mobile station, and a header provider which provides a header pattern corresponding to the first transmission number of the second frame. The mobile station retransmits the first frame when the mobile station does not receive the first transmission number indicated in the header pattern of the second frame.
