Abstract: Embodiments of the present invention provide a method for transmitting a pilot signal, a method for receiving a pilot signal, a user equipment (UE), and a base station. A method includes: determining a first downlink subframe according to an uplink and downlink ratio relationship, where the first downlink subframe is a first downlink subframe after a transition from uplink to downlink; transmitting a pilot signal to a UE in the first downlink subframe. Another method includes: determining, according to a preset transmit period and a subframe offset number, a second downlink subframe for transmitting a pilot signal, and transmitting the pilot signal to a UE in the second downlink subframe. According to the technical solution of the present invention, time domain resources occupied by a pilot signal are reduced, therefore, the overhead of transmitting the pilot signal is reduced.
