Method and wireless device for performing control channel selection within a dynamic frequency selection (DFS) avoidance system

A method of operating a first wireless device that is part of a wireless local area network (WLAN), the method comprising:

• determining, using historical radar event data associated with one or more dynamic frequency selection (DFS) channels, a first score for a first set of channels;
• determining, using the historical radar event data, a second score for a second set of channels;
• determining, using the first score and the second score, that a radar event is less likely to occur on the first set of channels than the second set of channels;
• determining, using historical interference data, a third score for at least one channel of a first bonded channel comprising at least the first set of channels;
• determining, using the third score for the at least one channel, a control channel from a plurality of channels of the first bonded channel;
• and
• sending, on the control channel, management information associated with the first bonded channel to a second wireless device of the WLAN.

A first wireless device that is part of a wireless local area network (WLAN), the first wireless device comprising:

• a WLAN radio;
• a memory device that stores data representing historical radar events and historical interference;
• and
• a processor coupled to the WLAN radio and the memory device, wherein the processor is to:
• determine, using historical radar event data associated with one or more dynamic frequency selection (DFS) channels, a first score for a first set of channels;
• determine, using the historical radar event data, a second score for a second set of channels;
• determine, using the first score and the second score, that a radar event is less likely to occur on the first set of channels than the second set of channels;
• determine, using historical interference data, a third score for at least one channel of a first bonded channel comprising at least the first set of channels;
• determine, using the third score for the at least one channel, a control channel from a plurality of channels of the first bonded channel;
• and
• send, on the control channel, management information associated with the first bonded channel to a second wireless device of the WLAN.
