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. |
