信道状态信息参考信号的传输方法、基站、终端、系统、机器可读程序和存储有机器可读程序的存储介质
摘要：
本发明实施例提供了一种信道状态信息参考信号(CSI‑RS)的传输方法，包括：从一个资源块中选取s组用于传输mi天线端口的CSI‑RS的资源元素，或从r个资源块中的每个资源块选取至少一个mj天线端口的CSI‑RS的资源元素，以组成n天线端口的CSI‑RS对应的资源元素组，n＞mi，n＞mj，1≤i≤s，1≤j≤r；将n天线端口的CSI‑RS经由资源元素组传输至终端，并通过指示信令告知终端相关信息。本发明还提供了基站、终端、系统、机器可读程序和存储有机器可读程序的存储介质。本发明可以根据现有的低数量天线端口的CSI‑RS信道状态信息参考信号，提供支持更多天线端口的CSI‑RS信道状态信息参考信号，从而充分发挥大规模天线系统的性能。
摘要（英）：

The present disclosure provides a transmission method of a channel state information reference signal (CSI-RS), including: selecting from a resource block s groups of resource elements for transmitting CSI-RSs of m i antenna ports, or selecting at least one resource element from each of r resource blocks for transmitting CSI-RSs of m j antenna ports, to constitute a resource element group to which CSI-RSs of n antenna ports correspond, n>m i , n>m j , 1‰¤i‰¤s, 1‰¤j‰¤r; transmitting the CSI-RSs of n antenna ports to a terminal via the resource elements, and informing related information to the terminal by using indication signaling. The present disclosure further provides a base station, a terminal, a system, a machine-readable program and a storage medium storing a machine-readable program. The present disclosure may provide CSI-RSs supporting more antenna ports according to CSI-RSs of existing antenna ports of a low number, thereby fully bringing performance of a large-scale antenna system into play.
