Abstract
A wireless device, for operation within a wireless network, the wireless device comprising: a RF transmitter, a RF receiver, and processing circuitry, where the RF transmitter sends a radar-detected message or a channel-switch announcement message to other wireless devices in the wireless networks. The other wireless devices receive the radar-detected message and abandon radar-detected channels designated in the radar-detected message. The other wireless devices also receive the channel-switch announcement message and switch to radar-free channels designated in the channel-switching message.
Claims10
A method implemented by a first device, the method comprising:
- performing a channel availability check (CAC) on a first channel, wherein the device has no connections to any other devices;
- detecting a radar signal on the first channel based on the CAC;
- switching to a slave mode;
- sending a radar detection message to a second device indicating a radar signal is detected in the first channel, wherein the radar detection message is sent after discovering the second device;
- and
- receiving a channel switch announcement (CSA), wherein the CSA indicates to switch to a second channel;
- switching to the second channel based on being in slave mode and receiving the CSA.
A device, the device comprising:
- a processor operatively connected to communication circuitry,
- the processor and communication circuitry configured to perform a channel availability check (CAC) on a first channel, wherein the device has no connections to any other devices;
- the processor and communication circuitry configured to detect a radar signal on the first channel based on the CAC;
- the processor and communication circuitry configured to switch to a slave mode;
- the processor and communication circuitry configured to send a radar detection message to a second device indicating a radar signal is detected in the first channel, wherein the radar detection message is sent after discovering the second device;
- and
- the processor and communication circuitry configured to receive a channel switch announcement (CSA), wherein the CSA indicates to switch to a second channel;
- the processor and communication circuitry configured to switching to the second channel based on being in slave mode and receiving the CSA.
