Abstract: Example communication methods and apparatus are described. One example method includes sending a first training signal by a first device to a second device on a reflection path. The first device sends a second training signal to the second device on the reflection path. The reflection path is a transmission path formed after the first training signal and the second training signal are reflected by a surrounding object. An interval between the first training signal and the second training signal is used to indicate to decode data.
