Abstract
The present disclosure provides a communication method of mapping CSI-RS ports to antenna units arranged in an antenna array system, a base station, and a user equipment, the communication method comprises steps of: selecting a group of antenna units to map to the CSI-RS ports in a first CSI-RS transmission period or a first frequency resource region; and selecting another group of antenna units to map to the CSI-RS ports in a second CSI-RS transmission period or a second frequency resource region. By the method, base station, and user equipment according to the present disclosure, each antenna unit would get a relatively fair opportunity for transmitting the CSI-RS signals or get a fairly good channel estimation performance in UE side.
