Method of transmitting transmission channel state information, and device, base station and terminal utilizing same

A Channel State Information-Reference Signal (CSI-RS) sending device, applied to a base station, wherein the device comprises:

• a processor;
• and
• a memory for storing instructions executable by the processor,
• wherein the processor is arranged to:
• send CSI-RSs through 16 CSI-RS ports, wherein the CSI-RSs are mapped to a Resource Element (RE) set in a CSI-RS pilot pattern, the RE set comprises REs to which CSI-RSs of 2 groups of 8 ports are mapped, a first group of CSI-RS port serial numbers and second group of CSI-RS port serial numbers for the 16 CSI-RS ports are mapped to REs to which CSI-RSs of the first group of 8 ports among the CSI-RSs of the two groups of 8 ports are mapped, and a third group of CSI-RS port serial numbers and fourth group of CSI-RS port serial numbers for the 16 CSI-RS ports are mapped to REs to which CSI-RSs of the second group of 8 ports among the CSI-RSs of the two groups of 8 ports are mapped,
• wherein each of the first group of CSI-RS port serial numbers, the second group of CSI-RS port serial numbers, the third group of CSI-RS port serial numbers and the fourth group of CSI-RS port serial numbers comprises 4 continuous CSI-RS port serial numbers, the first group of CSI-RS port serial numbers and the second group of CSI-RS port serial numbers are spaced by the third group of CSI-RS port serial numbers, and the third group of CSI-RS port serial numbers and the fourth group of CSI-RS port serial numbers are spaced by the second group of CSI-RS port serial numbers;
• and
• receive Channel State Information (CSI) measured by User Equipment (UE) on the basis of the CSI-RS.

A Channel State Information-Reference Signal (CSI-RS) sending method, applied to User Equipment (UE), the method comprising:

• receiving CSI-RSs sent by a base station according to CSI-RS pattern information;
• measuring Channel State Information (CSI) on the basis of the received CSI-RSs;
• and
• sending the measured CSI to the base station.
