Abstract

The present disclosure provides a method and system for transmitting a position reference signal, which includes: acquiring a currently needed Position Reference Signal (PRS) sequence with a length of 2×NRBPRS, wherein NRBPRS is the PRS bandwidth configured by high layer signaling, which is represented by a unit of a resource block; determining the position of the PRS sequence in a physical resource block; and transmitting the acquired PRS sequence on the determined position. With the method of the present disclosure, a currently needed PRS sequence is acquired directly, or at first, a PRS sequence with the maximum length is generated, and then the currently needed PRS sequence is intercepted from the PRS sequence with the maximum length. The present disclosure ensures that an effective PRS sequence can be acquired in any circumstance, thereby ensuring the realization of the positioning function of the PRS.
