Abstract:
The present invention relates to a method for terminal positioning. The method comprises: generating cell-specific reference signals CRSs, and transmitting the CRSs on one or more ports used for transmitting the CRSs; generating a positioning reference signal PRS, and transmitting the PRS on one of the one or more ports used for transmitting the CRSs. The method for terminal positioning provided by the embodiment of the present invention can reduce an impact caused by the limited number of symbols for transmitting the PRS, and increase the number of reference signal symbols available for positioning within a subframe, thereby reducing an impact of a secondary peak and enhancing the energy of a primary peak.
