Method and apparatus for determining position of client, and processor

A non-volatile computer-readable storage medium, comprising a stored program, wherein the program executes the following actions:

• a first acquisition step:
• acquiring at least one piece of first Channel State Information (CSI) from a first communication link for an Access Point (AP) to communicate with the client;
• a second acquisition step:
• when a first receiving antenna and a second receiving antenna of the AP meet a preset condition, acquiring at least one piece of second CSI from a second communication link for the AP to communicate with the client, wherein the preset condition is that a spacing between the first receiving antenna and the second receiving antenna of the AP is less than half of a signal wavelength, or after moving at least one receiving antenna, the spacing between the first receiving antenna and the second receiving antenna of the AP is less than half of the signal wavelength;
• a processing step:
• processing the first CSI to obtain a first phase difference, and processing the second CSI to obtain a second phase difference, wherein the first phase difference is a phase difference of a direct path from the client to the first receiving antenna, and the second phase difference is a phase difference of a direct path from the client to the second receiving antenna;
• and
• a determination step:
• determining a position of the client according to the first phase difference and the second phase difference.

A processor, configured to operate a program, wherein the following actions are executed when the program is operated:

• a first acquisition step:
• acquiring at least one piece of first Channel State Information (CSI) from a first communication link for an Access Point (AP) to communicate with the client;
• a second acquisition step:
• when a first receiving antenna and a second receiving antenna of the AP meet a preset condition, acquiring at least one piece of second CSI from a second communication link for the AP to communicate with the client, wherein the preset condition is that a spacing between the first receiving antenna and the second receiving antenna of the AP is less than half of a signal wavelength, or after moving at least one receiving antenna, the spacing between the first receiving antenna and the second receiving antenna of the AP is less than half of the signal wavelength;
• a processing step:
• processing the first CSI to obtain a first phase difference, and processing the second CSI to obtain a second phase difference, wherein the first phase difference is a phase difference of a direct path from the client to the first receiving antenna, and the second phase difference is a phase difference of a direct path from the client to the second receiving antenna;
• and
• a determination step:
• determining a position of the client according to the first phase difference and the second phase difference.
