First Claim
1. A wireless communication system, comprising:
- a network including a plurality of wireless communication apparatuses that operate in an autonomous distributed manner without any of the wireless communication apparatuses being a specific controlling station, at least one of the wireless communication apparatuses including;
a transmitting-side or receiving-side communication apparatus which attempts to perform communication in a predetermined bandwidth, issues a notification indicating a setting of a period during which availability of the predetermined bandwidth is guaranteed in a communication range so that any other communication apparatus that receives the notification does not perform a communication operation in the predetermined bandwidth during the guaranteed period,wherein, for each predetermined frame period, regardless of whether the wireless communication apparatus is the transmitting-side or the receiving-side communication apparatus, the wireless communication apparatus transmits beacon information that describes information regarding the guaranteed 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.
