Method and device for notifying reference signal configuration information

A terminal device, comprising a transceiver, a memory and a processor coupled with the transceiver and the memory, wherein

• the transceiver is configured to:
• receive channel state information-reference signal (CSI-RS) configuration codes from a base station, wherein the CSI-RS configuration codes comprise a first code, a second code and a third code;
• and
• the processor is configured to:
• determine a CSI-RS pattern according to a relationship between the first code, the number of antenna ports of the base station and the CSI-RS pattern stored in the memory,
• determine a CSI-RS period and a sub-frame offset according to a relationship between the second code, the CSI-RS period and the sub-frame offset stored in the memory, and
• determine a data muting position according to the third code.

An apparatus, comprising a processor coupled with a non-transitory storage medium storing executable instructions;

• wherein the executable instructions, when executed by the processor, cause the processor to:
• obtain channel state information-reference signal (CSI-RS) configuration codes from a signaling received from a base station, wherein the CSI-RS configuration codes comprise a first code, a second code and a third code;
• determine a CSI-RS pattern according to a relationship between the first code, the number of antenna ports of the base station and the CSI-RS pattern,
• determine a CSI-RS period and a sub-frame offset according to a relationship between the second code, the CSI-RS period and the sub-frame offset, and
• determine a data muting position according to the third code.
