Method and device for sending user-specific reference signal

A base station, comprising:

• a processor;
• and
• a non-transitory processor-readable medium having processor-executable instructions stored thereon that, when executed by the processor, cause the base station to:
• determine a modulus identification;
• perform an interference elimination processing on a user-specific reference signal based on the modulus identification to obtain an interference-eliminated user-specific reference signal;
• perform a beamforming processing on the interference-eliminated user-specific reference signal to obtain a beamformed reference signal;
• perform an inverse fast fourier transform (IFFT) and a digital-to-analogue conversion on the beamformed reference signal to obtain an analogue signal for the user-specific reference signal;
• and
• transmit the analogue signal to a user terminal.

A non-transitory computer-readable medium storing therein a set of processor-executable instructions that, when executed by a processor, cause the processor to execute the steps of:

• determining a modulus identification, and performing an interference elimination processing on a user-specific reference signal based on the modulus identification to obtain an interference-eliminated user-specific reference signal;
• performing a beamforming processing on the interference-eliminated user-specific reference signal to obtain a beamformed reference signal;
• and
• performing an inverse fast fourier transform (IFFT) and a digital-analogue conversion on the beamformed reference signal to obtain an analogue signal for the user-specific reference signal, and transmitting the analogue signal to a user terminal.
