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

An information processing apparatus used for a wireless communication, comprising:

• a transmitting unit which transmits a transmission data and receives an acknowledgement data corresponding to said transmission data through a communication line;
• a monitoring unit which monitors said transmission data and said acknowledgement data;
• and
• a determining unit which determines a retransmission timeout period based on a monitored result by said monitoring unit in a certain period;
• wherein said transmitting unit retransmits said transmission data when said acknowledgement data is not received in said retransmission timeout period.

A mobile terminal used for a wireless communication, comprising:

• a transmitting unit which transmits a transmission data and receives an acknowledgement data corresponding to said transmission data through a communication line;
• a monitoring unit which monitors said transmission data and said acknowledgement data;
• and
• a determining unit which determines a retransmission timeout period based on a monitored result by said monitoring unit in a certain period;
• wherein said transmitting unit retransmits said transmission data when said acknowledgement data is not received in said retransmission timeout period.

A determination method of a retransmission timeout period, comprising:

• transmitting a transmission data and receiving an acknowledgement data which corresponds to said transmission data through a communication line;
• monitoring said transmission data and said acknowledgement data;
• and
• determining a retransmission timeout period based on a monitored result in a certain period;
• wherein said transmission data is retransmitted when said acknowledgement data is not received in said retransmission timeout period.

A computer program product embodied on a computer-readable medium and comprising code that, when executed, causes a computer to perform the following:

• transmitting a transmission data and receiving an acknowledgement data which corresponds to said transmission data through a communication line;
• monitoring said transmission data and said acknowledgement data;
• and
• determining a retransmission timeout period based on a monitored result in a certain period;
• wherein said transmission data is retransmitted when said acknowledgement data is not received in said retransmission timeout period.
