Abstract: A data sending method, a related device, and a system are described. The method includes sending, by a network device, resource location information of a first reference signal and a physical channel to a terminal, where a first time-frequency resource on which the first reference signal is mapped overlaps a second time-frequency resource corresponding to the physical channel. An overlapping resource is not used to transmit the physical channel, and a third time-frequency resource in the second time-frequency resource other than the overlapping resource is used to transmit the physical channel. Alternatively, an overlapping resource is used to send a second reference signal; or an overlapping region is used to send a second reference signal, where the terminal skips sending the first reference signal, and the second reference signal is orthogonal to the first reference signal.
