|発明の名称||COMMUNICATION APPARATUS AND RADIO COMMUNICATION METHOD|
PROBLEM TO BE SOLVED: To avoid a collision while fairly allocating radio resources to wireless LANs in a radio communication system in which the wireless LANs of which the times required for carrier sense are different coexist.
SOLUTION: A communication apparatus 3 is configured to immediately start a data transmission without performing carrier sense after a data transmission of the other communication apparatus in a radio communication system in which a collision of data transmissions is avoided by the carrier sense. One communication apparatus comprises: a data receiving section 523 for measuring a communication volume of the other communication apparatus; a data transmitting section 522 for executing a data transmission with predetermined probability in timing when the data transmission of the one communication apparatus is made possible; and a transmission waiting probability calculation section 524 for determining the probability based on the communication volume of the other communication apparatus that is measured by the data receiving section 523.
