Method for transmitting a channel state information-reference signal, processor, base station and storage medium

A processor, configured to execute programs, wherein when the processor executes the programs, the processor executes a method for transmitting a CSI-RS

• wherein the method comprises:
• determining, by a base station, information of the CSI-RS, wherein the information of the CSI-RS at least comprises a number of CSI-RS ports and information of components of a CSI-RS resource, wherein the CSI-RS ports are used for transmitting the CSI-RS, and the CSI-RS resource is used for carrying the CSI-RS;
• transmitting, by the base station, the information of the CSI-RS to a terminal;
• and
• transmitting, by the base station, the CSI-RS;
• wherein the information of the components comprises time domain positions and frequency domain positions of the components, and notifying, by the base station, the terminal of the information of the components comprises at least one of the following:
• notifying, by the base station, the terminal of a position of an earliest orthogonal frequency division multiplexing (OFDM) symbol of the components on the time domain positions and a position of a lowest-frequency subcarrier of the components on the frequency domain positions;
• notifying, by the base station, the terminal of a position of a latest OFDM symbol of the components on the time domain positions and a position of a highest-frequency subcarrier of the components on the frequency domain positions;
• or
• notifying, by the base station, the terminal of a position of a latest OFDM symbol of the components on the time domain positions and a position of a lowest-frequency subcarrier of the components on the frequency domain positions.

A base station, comprising a processor, a memory and a transceiver;

• wherein
• the memory is configured to store executable instructions;
• the transceiver is configured to perform information transceiving communication according to control of the processor;
• and
• the processor is configured to execute following operations:
• determining information of channel state information-reference signal,
• wherein the information of the CSI-RS at least comprises a number of CSI-RS ports and information of components of a CSI-Rs resource, wherein the CSI-RS ports are configured to transmit the CSI-RS, and the CSI-RS resource is used for carrying the CSI-RS;
• sending the information of the CSI-RS to a terminal;
• and
• transmitting the CSI-RS;
• wherein the information of the components comprises time domain positions and frequency domain positions of the components, and notifying the terminal of the information of the components comprises at least one of the following:
• notifying the terminal of a position of an earliest orthogonal frequency division multiplexing (OFDM) symbol of the components on the time domain positions and a position of a lowest-frequency subcarrier of the components on the frequency domain positions;
• notifying the terminal of a position of a latest OFDM symbol of the components on the time domain positions and a position of a highest-frequency subcarrier of the components on the frequency domain positions;
• or
• notifying the terminal of a position of a latest OFDM symbol of the components on the time domain positions and a position of a lowest-frequency subcarrier of the components on the frequency domain positions.
