<p>PROBLEM TO BE SOLVED: To provide a radio communication system capable of keeping quality of transmission data while reducing power consumption caused by communication.SOLUTION: A communication apparatus 1A as a call origination station includes a control unit 10 which: makes a storage unit 13 store data and data identification information of a transmitted communication packet when the communication packet is not received by a communication apparatus 1B as a reception station; and makes a transmission unit 11 transmit a new communication packet including the data and data dentification information read out from the storage unit 13 when transmitting the new communication packet the next time. The communication apparatus 1B includes a control unit 10 which: makes the transmission unit 11 return an ACK signal when the communication apparatus 1B receives a communication packet from the communication apparatus 1A; makes the storage unit 13 store data and data identification information received by a reception unit 12 when the same data identification information as the received data identification information is not stored in the storage unit 13; and discards the received data and data identification information when the same data identification information is stored in the storage unit 13.</p> |
