Abstract:
The disclosure provides a method of transmitting transmission channel state information, and device, base station and terminal utilizing the same. The method comprises: transmitting, by 16 channel state information reference signal (CSI-RS) ports, CSI-RSs, wherein the CSI-RSs are mapped to a resource element (RE) set in CSI-RS pilot patterns, the RE set comprises REs mapping to 2 sets of 8 CSI-RS ports, a first set of CSI-RS port serial numbers and a second set of the CSI-RS port serial numbers in the 16 CSI-RS ports are mapped to REs mapping to a first set of the 8 CSI-RS ports in the 2 sets of the 8 CSI-RS ports, and a third set of CSI-RS port serial numbers and a fourth set of the CSI-RS port serial numbers in the 16 CSI-RS ports are mapped to REs mapping to a second set of the 8 CSI-RS ports in the 2 sets of the 8 CSI-RS ports; and measuring, by a receiving end, according to the CSI-RSs, channel state information. The embodiments of the disclosure can reduce repeated CSI-RS overheads, while increasing accuracy of a CSI measurement comparing to a conventional terminal, enhancing performance of a base station.

Claim (Index 3):
The method according to  claim 1 , wherein two continuous CSI-RS port serial numbers among the first group of CSI-RS port serial numbers are mapped to two REs located on a first subcarrier, and the other two continuous CSI-RS port serial numbers among the first group of CSI-RS port serial numbers are mapped to two REs located on a second subcarrier, wherein the first subcarrier and the second subcarrier are spaced by 5 subcarriers, and are two subcarriers among 4 subcarriers where the mapped REs for the CSI-RSs of the first group of 8 ports are located.
