Description

TECHNICAL FIELD

[0001] The present invention relates to a terminal whose opportunity to access a communication medium is controlled by a control station, and more particularly, to a terminal capable of substituting for a control station. BACKGROUND ART

[0002] A communication system which utilizes media having a problem with communication quality is provided with a control station for controlling media access of other station(s) in order to utilize media as efficiently as possible. The other station is regarded as a controlled station, i.e., the control station and the controlled station have a master-slave relationship. In this manner, a central control type communication system protocol which can improve the efficiency of the entire communication system has been developed.

[0003] When such a protocol is applied to a wireless LAN, a power line communication system and the like, the efficiency of media access in the communication system is significantly influenced by communication qu...
