1. A method for transmitting a positioning reference signal, comprising:
mapping, by a base station, according to configuration information of a positioning reference signal (PRS), a PRS sequence to a time-frequency resource for sending the PRS;
sending, by the base station, the configuration information of the PRS to a terminal; and
sending, by the base station, a mapped PRS on the time-frequency resource for sending the PRS;
wherein the subcarrier spacing of PRSs is ΔfPRS=15×2μ kHz, and μ is equal to one of 0, 1, 2 or 3.
