Disclosed are a method and device for sending a user-specific reference signal. The method provided in the present invention includes: determining a modulus identification, and performing interference elimination processing on a user-specific reference signal according to the modulus identification to obtain the user-specific reference signal after the interference elimination processing; performing beamforming processing on the user-specific reference signal after the interference elimination processing to obtain a beamforming reference signal; and performing inverse fast fourier transform (IFFT) and digital-analog conversion on the beamforming reference signal to obtain an analog signal of the user-specific reference signal, and sending the analog signal to a user terminal.
