Proxy-based ranging in a wireless communication system

An apparatus for wireless communication, comprising:

• a ranging proxy indicator identifier to receive, at a first wireless device, a ranging proxy indicator from a candidate ranging proxy;
• a ranging indicator identifier to identify a first ranging indicator based at least in part on the ranging proxy indicator, the first ranging indicator indicating a proximity of the first wireless device to the candidate ranging proxy;
• a ranging indicator receiver to receive a second ranging indicator indicating a proximity of a second wireless device to the candidate ranging proxy;
• and
• a device proximity identifier to identify the first wireless device and the second wireless device being within a proximity threshold based at least in part on the first ranging indicator and the second ranging indicator.

An apparatus for wireless communication, comprising:

• a processor;
• memory in electronic communication with the processor;
• and
• instructions stored in the memory, the instructions being executable by the processor to:
• receive a ranging proxy indicator from a candidate ranging proxy;
• identify a first ranging indicator based at least in part on the ranging proxy indicator, the first ranging indicator indicating a proximity of the apparatus to the candidate ranging proxy;
• receive a second ranging indicator indicating a proximity of a second apparatus to the candidate ranging proxy;
• and
• identify the apparatus and the second apparatus being within a proximity threshold based at least in part on the first ranging indicator and the second ranging indicator.

A non-transitory computer-readable medium storing computer-executable code for wireless communication, the code executable by a processor to:

• receive, at a first wireless device, a ranging proxy indicator from a candidate ranging proxy;
• identify a first ranging indicator based at least in part on the ranging proxy indicator, the first ranging indicator indicating a proximity of the first wireless device to the candidate ranging proxy;
• receive a second ranging indicator indicating a proximity of a second wireless device to the candidate ranging proxy;
• and
• identify the first wireless device and the second wireless device being within a proximity threshold based at least in part on the first ranging indicator and the second ranging indicator.
