SYSTEM, DEVICE, AND METHOD FOR SELECTING A CHANNEL IN A MULTICHANNEL COMMUNICATION NETWORK

摘要

In a system, device, and method for selecting a channel from among a plurality of channels, a number of available channels are selected for testing. A channel quality measurement is made for each of the number of channels. The channel having the best channel quality measurement is then selected. To make the channel quality measurements, a primary station selects a channel to be tested (304) and also selects a secondary station with which to perform the test (306). The primary station transmits a control frame to the selected secondary station, including a channel identifier identifying the selected channel (308). Upon receiving the control frame (310), the selected secondary station adjusts its transmitter to the selected channel based on the channel identifier in the control frame, and transmits a reference signal on the selected channel (312). Meanwhile, the primary station adjusts its receiver to the selected channel and receives the reference signal from the selected secondary station (314). The primary station then measures the quality of the received reference signal (316).
