Patent ID: 8179856

Claim:
A communication device, comprising: a first communication section and a second communication section that use a band causing a conflict between the first communication section and the second communication section; and a compressibility adjusting section for changing a compressibility of communication data to be transmitted by the second communication section based on a communication status of the first communication section, the communication status of the second communication section, and a value of a retransmission ratio of the communication data to be transmitted by the second communication section, wherein the compressibility adjusting section calculates a value of the compressibility according to the value of the retransmission ratio so as to control an amount of data to be transmitted, including retransmission, per unit time within the band, and wherein processing to calculate the value of the compressibility and to adjust the compressibility to the calculated value is repeatedly executed every predetermined period of time while the second communication section transmits data according to a predetermined communication protocol.
