First Claim
1. A wireless communication system that forms a network in an autonomous distributed manner without a specific controlling station, the wireless communication system comprising:
- a transmitting-side or receiving-side communication apparatus that sets a priority utilization period utilizable with priority in a frame period thereof and which performs communication with a guaranteed bandwidth utilizing the priority utilization period with a priority,wherein the transmitting-side or receiving-side communication apparatus temporarily delays a start of performing communication and performs transmission based on a priority utilization after an end of another communication if the another communication is being performed when the priority utilization period begins.

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.

8. A wireless communication apparatus that performs a wireless communication operation in an autonomous distributed manner without a specific controlling station, the wireless communication apparatus comprising:
-
communication means for transmitting/receiving a wireless signal in its own communication range; priority-utilization-period setting means for setting a priority utilization period for performing communication with a guaranteed bandwidth in its own frame period and for notifying, within the own communication range, of the priority utilization period; and communication controlling means for performing communication with a guaranteed bandwidth, with priority, in response to an arrival of the priority utilization period, wherein the communication controlling means temporarily delays a start of communication in the priority utilization period and performs transmission based on a priority utilization after an end of another communication, if the another communication is performed at a time when the priority utilization period arrives. - View Dependent Claims (9, 10, 11, 12, 13, 14)
