Parameter update for range-based positioning

A non-transitory computer-readable storage medium that stores instructions for execution by one or more processors of an apparatus of a station (STA), the instructions to configure the one or more processors to:

• perform a distance estimating method with access points (APs) to determine first distance estimates between the APs and the STA, the distant estimating method comprising parameters;
• determine a location of the STA based on the first distance estimates between the APs and the STAs and locations of the APs;
• update the parameters by subtracting from a parameter of the parameters a learning rate times a derivative of a cost function with respect to the parameter, wherein the cost function is based on the determined location of the STA, the locations of the APs, and the first distance estimates between the APs and the STA;
• move a physical location of the STA;
• perform the distance estimating method with the APs to determine second distance estimates, wherein the updated parameters are used to determine the second distance estimates;
• determine another location of the STA based on the second distance estimates between the APs and the STAs and the locations of the APs;
• and
• update the updated parameters by subtracting from an updated parameter of the updated parameters the learning rate times the derivative of the cost function with respect to the parameter.

An apparatus of a system, the apparatus comprising memory;

• and processing circuitry coupled to the memory, the processing circuitry configured to:
• receive first distance estimates between access points (APs) and a station (STA), wherein the distance estimates were determined based on a method performed between the APs and the STA, the distant estimating method comprising parameters;
• determine a location of the STA based on the first distance estimates between the APs and the STAs and locations of the APs;
• update the parameters by subtracting from a parameter of the parameters a learning rate times a derivative of a cost function with respect to the parameter, wherein the cost function is based on the determined location of the STA, the locations of the APs, and the first distance estimates between the APs and the STA;
• send the updated parameters to the APs;
• receive second distance estimates between APs and the STA, wherein the second distance estimates were determined based on the distant estimating method comprising the updated parameter;
• determine another location of the STA based on the second distance estimates between the APs and the STAs and the locations of the APs;
• update the updated parameters, to generate twice updated parameters, by subtracting from a parameter of the updated parameters the learning rate times the derivative of the cost function with respect to the parameter;
• and
• send the twice updated parameters to the APs.
