This application provides a pilot signal transmission method, a base station, and user equipment. A dedicated demodulation pilot signal and a common demodulation pilot signal in a TTI may be configured on different resource blocks of the TTI. The method in embodiments of the present invention includes: determining, by a base station, a resource location that is in a TTI and that is used to send a pilot signal, where the pilot signal includes a common demodulation pilot signal and a dedicated demodulation pilot signal, and the dedicated demodulation pilot signal and the common demodulation pilot signal are located on different resource blocks of the TTI; and sending, by the base station, the pilot signal at the resource location used to send the pilot signal.
