The embodiments of the invention disclose a pilot signal transmission method, terminal equipment, and network equipment. The method comprises: terminal equipment determines, from a plurality of pilot patterns, a first pilot pattern; the terminal equipment determines, according to the first pilot pattern, a time-frequency resource used to transmit a pilot signal; and the terminal equipment transmits or receives, using the time-frequency resource, the pilot signal. In the embodiments of the invention, the pilot signal transmission method, terminal equipment, and network equipment can flexibly adjust pilot density and physical resources, thereby reducing pilot overhead.
