Abstract: A distance measurement method. A first electronic device establishes a communication connection to a second electronic device. The first electronic device receives a distance measurement instruction. The first electronic device receives a plurality of groups of sound wave signals sent by a speaker in the second electronic device. Then, the first electronic device determines, based on the plurality of groups of sound wave signals, a sending moment, and a sound wave velocity, a real-time distance between the first electronic device and the second electronic device when each group of sound wave signals are received by the first electronic device. Finally, the first electronic device continuously refreshes and displays the real-time distance between the first electronic device and the second electronic device that is obtained through calculation to improve display precision.

Abstract: The present disclosure provides a channel measurement method and a STA to ensure that a sub-channel on which channel measurement is performed is idle, thereby preventing, to some extent, transmission in an OBSS from being affected by UL channel measurement. The method includes: receiving, by a station STA, a measurement notification message sent by an access point AP, where the measurement notification message carries identifier information of a channel that needs to be measured; and sending, by the STA, a sounding reference signal by using M idle sub-channels, so that the AP measures the M idle sub-channels according to the received sounding reference signal, where the M idle sub-channels are M idle sub-channels determined by the STA from at least one sub-channel included in a channel indicated in the identifier information of the channel that needs to be measured, and M is an integer greater than or equal to 1.
