Abstract
Disclosed are a method and device for transmitting a positioning reference signal. In the method, a base station maps, according to configuration information of a PRS, a PRS sequence to a time-frequency resource for sending a PRS; and the base station sends the configuration information of the PRS to a terminal, and sends the mapped PRS on the time-frequency resource for sending a PRS.
Claims18
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.
