Wireless communication system which improves reliability and throughut of communication and retransmission timeout determining method used for the same

摘要

A wireless communication system includes a mobile terminal, a base station apparatus, a data relay apparatus and a server apparatus. One of the mobile terminal, the base station apparatus, the data relay apparatus and the server apparatus includes a transmitting unit, a monitoring unit and a determining unit. The transmitting unit transmits a transmission data and receives an acknowledgement data corresponding to the transmission data through a communication line. The monitoring unit monitors the transmission data and the acknowledgement data. The determining unit determines a retransmission timeout period based on a monitored result by the monitoring unit in a certain period. The transmitting unit retransmits the transmission data when the acknowledgement data is not received in the retransmission timeout period.
