First Claim
1. A first communication device for wirelessly communication according to IEEE802.11 standard comprising:
- circuitry configured to;
transmit a reservation request having information for setting a reservation period for the first communication device to a second communication device capable of performing wireless communication according to the IEEE802.11 standard with a third communication device; and
receive a response acknowledging the reservation period in the reservation request from the second communication device;
wherein the second communication device is configured to continue transmitting information related to the reservation period until termination of reservation processing, andwherein the circuitry is configured to transmit data during the reservation period.

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.
