Positioning method and device

[0046] Example one

[0047] Such as figure 1 As shown, an embodiment of the present invention provides a positioning method for the problems in the prior art, and the specific implementation includes the steps:

[0048] Step 101: The access point (AccessPoint, AP) uses M*K different channels formed by M antennas to send M*K positioning inquiry signaling to the station (Station, STA), where the M*K different channels Each channel sends a positioning query signaling, M and K are positive integers;

[0049] In the embodiment of the present invention, the AP can form M*K different channels by changing the polarization modes or frequency bands of the M antennas. And the AP may also use positioning request signaling to send positioning inquiry signaling to the STA, so that the STA feeds back corresponding signaling for positioning after receiving the positioning inquiry signaling.

[0050] In addition, because the M antennas set by the AP can all operate independently, the way that the AP use

[0084] Example two

[0085] Such as figure 2 As shown, when the AP adopts the method of adjusting the polarization of the antenna to provide multiple different types of characteristic channels, the positioning method provided by the embodiment of the present invention, the specific implementation includes the steps:

[0086] Step 201: The access point AP adjusts the polarization modes of the M antennas to form M*K different channels, and uses the M*K different channels to send M*K positioning query signaling to the station STA, where: Each of M*K different channels sends a positioning inquiry signaling, M and K are positive integers;

[0087] In the embodiment of the present invention, the AP is provided with M antennas, and each antenna may have at least K polarization modes. When the AP adjusts the polarization of each antenna at intervals, a new characteristic channel will be formed every time the antenna is adjusted. Therefore, by adjusting the polarization of the antenna at inter

[0096] Example three

[0097] Such as image 3 As shown, when the AP uses the frequency band of adjusting the antenna to provide multiple different types of characteristic channels, the positioning method provided in the embodiment of the present invention is specifically implemented including the steps:

[0098] Step 301: The access point AP adjusts the frequency bands of the M antennas to form M*K different channels, and uses the M*K different channels to send M*K positioning inquiry signaling to the station STA, where M* Each of K different channels sends a positioning query signaling, M and K are positive integers;

[0099] In the embodiment of the present invention, the AP is provided with M antennas, and each antenna can have at least K frequency bands (the current 11AC standard in the technology has multiple 20M frequency bands for each antenna, and one or several frequency bands can be used each time. ), when the AP adjusts the frequency band used by each antenna once a period
