Optically-assisted calibration

A method of wireless communication at a first user equipment (UE), comprising:

• estimating a first distance between the first UE and a second UE using at least one of an optical sensor or a calibrated radio-frequency (RF)-based ranging mechanism;
• estimating a second distance between the first UE and the second UE using a non-calibrated RF-based ranging mechanism;
• computing an offset that indicates a difference between the estimated first distance and the estimated second distance, wherein the offset is associated with the non-calibrated RF-based ranging mechanism between the first UE and the second UE;
• and
• outputting an indication of the offset that indicates the difference between the estimated first distance and the estimated second distance.

An apparatus for wireless communication at a first user equipment (UE), comprising:

• a user interface (UI);
• at least one memory;
• and
• at least one processor coupled to the at least one memory, the at least one processor, individually or in any combination, is configured to:
• provide, at the UI, a guidance for placing a second UE at a designated area or in front of a camera of the first UE;
• estimate a first distance between the first UE and the second UE using at least one of an optical sensor or a calibrated radio-frequency (RF)-based ranging mechanism;
• estimate a second distance between the first UE and the second UE using a non-calibrated RF-based ranging mechanism;
• compute an offset that indicates a difference between the estimated first distance and the estimated second distance, wherein the offset is associated with the non-calibrated RF-based ranging mechanism between the first UE and the second UE;
• and
• output an indication of the offset that indicates the difference between the estimated first distance and the estimated second distance.
