Abstract
A phase-based ranging method and a related apparatus are disclosed. The ranging method includes: receiving a first multi-tone signal sent by a second transceiver, where the first multi-tone signal includes N first single-frequency signals, the N first single-frequency signals are obtained through negotiation between a first transceiver and the second transceiver, and N is an integer greater than 1; performing down conversion on the first multi-tone signal based on each of the N first single-frequency signals to obtain N direct current (DC) signals, where each of the N first single-frequency signals corresponds to one of the N DC signals; and measuring a first phase of each of the N DC signals to obtain a first phase value sequence.
