MOBILE COMMUNICATION METHOD AND SYSTEM

PROBLEM TO BE SOLVED: To provide a mobile communication method and system capable of easily specifying a retransmission buffer to which frame data are stored, decreasing the number of the retransmission buffers and eliminating the need for search processing for recognizing whether or not data are re-transmission frame data. SOLUTION: The mobile communication system for wirelessly transmitting / receiving data between first and second communication apparatuses 1, 2 is configured by including: a buffer management number provision means 10 for providing a buffer management number used for storing a position in use of the retransmission buffer to an overhead part of frames; and a control means 11 for starting the buffer management number provision means 10 to write the buffer number used for retransmission to a buffer management number storage section and retransmitting frame data when receiving a control signal denoting data reception abnormity from an opposite receiver in the case that either of the communication apparatuses acts like a transmission apparatus.
