Abstract
A multi-channel scheduling method in a wireless network is provided. The wireless network includes a plurality of Wireless Local Area Network (WLAN) device with a single radio interface. A regular time interval P and a Channel Coordination Window (CCW) to be repeated in a period of P are set. A request is made such that the plurality of devices are tuned to a first channel at a start point of the CCW. A pair of arbitrary WLAN devices among the plurality of WLAN devices is allowed to transmit control frames in the regular time interval P. The control frames are a transmission proposal control frame for proposing communication in a second channel and a response frame, responding to the transmission proposal control frame, for indicating whether the second channel has been accepted or rejected. The arbitrary WLAN device of the pair are switched to the second channel after acceptance.
