Abstract
A wireless communication apparatus includes, a transceiver module performs data transmission; and a processing module selects a channel whose bandwidth is a to-be-detected bandwidth from a WLAN system. If there is no idle channel, detection is performed again after the to-be-detected bandwidth is reduced.
Claims16
A wireless communication apparatus, comprising:
- a transceiver configured to perform data transmission;
- and
- a processor configured to:
- (a) select a channel whose bandwidth is a to-be-detected bandwidth from the WLAN system, wherein the to-be-detected bandwidth is an integer multiple of a basic bandwidth of the WLAN system, and an initial value is greater than the basic bandwidth of the WLAN system,
- (b) detect whether the selected channel whose bandwidth is the to-be-detected bandwidth is idle,
- (c) when a detection result is idle, control the transceiver to use the channel to perform data transmission, or when a detection result is busy, select another channel whose bandwidth is the to-be-detected bandwidth from the WLAN system and return to the step (b), and
- when it is detected that all selected channels whose bandwidth is the to-be-detected bandwidth in the WLAN system are busy, and the to-be-detected bandwidth is greater than the basic bandwidth of the WLAN system, reduce the to-be-detected bandwidth and return to the step (a).

A channel detection method, comprising:
- selecting a channel whose bandwidth is a to-be-detected bandwidth from a WLAN system, wherein the to-be-detected bandwidth is an integer multiple of a basic bandwidth of the WLAN system, and an initial value is greater than the basic bandwidth of the WLAN system;
- detecting whether the selected channel whose bandwidth is the to-be-detected bandwidth is idle;
- when a detection result is idle, using the channel to perform data transmission, or when a detection result is busy, selecting another channel whose bandwidth is the to-be-detected bandwidth from the WLAN system, and returning to the step of detecting whether the selected channel whose bandwidth is the to-be-detected bandwidth is idle;
- and
- when it is detected that all selected channels whose bandwidth is the to-be-detected bandwidth in the WLAN system are busy, and the to-be-detected bandwidth is greater than the basic bandwidth of the WLAN system, reducing the to-be-detected bandwidth and returning to the step of selecting a channel.
