Abstract: Example ranging methods and apparatus are described. In one example method, a first device sends ranging control information to a second device through a first channel, where the ranging control information is used to configure a ranging frame. The first device receives or sends the ranging frame through a second channel, where a bandwidth of the second channel is greater than a bandwidth of the first channel. Based on the foregoing solution, the first device and the second device may exchange the ranging control information and a measurement result through the first channel, and perform ranging through the second channel.

Abstract: The present disclosure relates to signal transmission methods, apparatuses, and systems. One example method includes sending a narrow band signal to a receive end, where the narrow band signal is used by the receive end to determine initial time-frequency synchronization information, and sending an ultra-wideband signal to the receive end, where the ultra-wideband signal includes a channel impulse response training sequence (CTS) field, the CTS field is used by the receive end to determine a channel impulse response, the CTS field includes at least one CTS symbol, and the CTS symbol includes at least one first preamble symbol or is generated by spreading at least one first preamble symbol.
