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.

Claims

1. A first wireless communication device for exchanging beacons with other wireless communication devices comprising:

circuitry configured to

transmit a request for reserving a radio resource for the first wireless communication device to a second wireless communication device capable of wirelessly communicating with a third wireless communication device, the third wireless communication device being hidden from the first wireless communication device;

receive a response to the request from the second wireless communication device, the response specifying timing of a period for transmitting data from the first communication device; and

transmit data at a timing determined based on the timing of the period specified in the response.
