Title:
COMMUNICATION SYSTEM, COMMUNICATION APPARATUS AND COMMUNICATION METHOD, AND COMPUTER PROGRAM
Document Type and Number:
Japanese Patent JP2010263492
Kind Code:
A
Abstract:

To appropriately implement space division multiple access while avoiding network interference.

Time utilization information of a transmission/reception sequence unit between different networks or between devices, to which a communication station that initiates the transmission/reception sequence unit is not adjacent, is exchanged and on the basis of the information, the communication station disposes the time to initiate the transmission/reception sequence unit of the station's own in a time zone that is not utilized by the adjacent network or the adjacent device. As a result, even if it is difficult to exclusively dispose a frequency channel, a plurality of wireless networks or wireless communication devices can utilize the channel in a time division manner, thereby implementing efficient space division multiple access.
