Abstract: A wireless communication network that forms an ad-hoc network without the arrangement of a controlling station sets a period that a communication apparatus can utilize with priority and performs isochronous communication in the period as required. When isochronous communication has not been performed or after isochronous communication has finished in the priority utilization period, other communication apparatuses perform arbitrary communication. When another communication is performed in a communication apparatus's own priority utilization period, the start of isochronous communication is temporarily delayed. In an ad-hoc communication environment, data having a real-time characteristic, such as AV content, can be efficiently transmitted through the isochronous communication.
