METHOD AND SYSTEM FOR TRANSMITTING POSITION REFERENCE SIGNAL.

摘要

The present invention discloses a method and system for transmitting position reference signal, and the method includes the following steps: the frequency domain positions for transmitting the position reference signal are n physical resource blocks, and the value of n is obtained based on signaling; the time domain positions for transmitting the position reference signal are as follows: the orthogonal frequency division multiplexing symbols of sub-frames except for the orthogonal frequency division multiplexing symbols for transmitting physical downlink control channel and cell-specific reference signal; transmitting the position reference signal according to the frequency domain positions and time domain positions. With the method and system of the present invention, the transmission of position reference signal is implemented and the position accuracy of UE can be ensured.
