Abstract: A data transmission method and apparatus, and relates to the communication field. In the method, after obtaining a path parameter of each of at least one communication path between a first device and a second device, the first device may demodulate first data based on a pilot and the path parameter of each communication path. In other words, when demodulating the first data, the first device may refer to not only the pilot but also the path parameter of each communication path. The path parameter of each communication path can assist in demodulating the first data. When the path parameter of each communication path assists in demodulating the first data, there may be no need for too many pilots. Therefore, a resource occupied by the pilot can be reduced.
