Wireless communication system, wireless communication apparatus, wireless communication method, and computer program
First Claim
1. A wireless communication system that forms a network in an autonomous distributed manner without the network having a specific controlling station, the wireless communication system comprising:
- a transmitting-side or receiving-side communication apparatus that sets a priority utilization period utilizable for communication by the transmitting-side or receiving-side communication apparatus with priority over other communication in its own frame period and which performs the communication with a guaranteed bandwidth utilizing the priority utilization period with priority,wherein the transmitting-side or receiving-side communication apparatus temporarily delays a start of performing the communication and performs the communication with priority 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 forms a network and performs a wireless communication operation in an autonomous distributed manner without the network having a specific controlling station, the wireless communication apparatus comprising:
-
communication means for transmitting/receiving a wireless signal within its 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 its 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 its own priority utilization period, wherein the communication controlling means temporarily delays a start of the communication in the priority utilization period and performs the communication with priority after an end of another communication if the another communication is being performed at a time when the priority utilization period set by the priority-utilization-period setting means arrives. - View Dependent Claims (9, 10, 11, 12, 13, 14)
