CONTROL STATION FOR PERFORMING DATA RETRANSMISSION

摘要

PROBLEM TO BE SOLVED: To provide a radio communication system capable of performing data retransmission control without spoiling real time nature. SOLUTION: A control station 11 transmits a packet during a noncollision period. A receiving station 12 transmits a response specifying the packet received from the control station 11 during the noncollision period of time. The control station 11 determines whether the transmitted packet has been received on the basis of a reception response from the receiving station 12, and retransmits an unreceived packet during a collision period following the noncollision period.
