Method and a base station for transmitting a CSI-RS, and a method and user equipment for receiving the CSI-RS
摘要:
A base station in a wireless communication system transmits a CSI-RS of a cell every 1×N subframes or 1×N ms with muting CSI-RS REs of a neighboring cell every m×N subframes. A BS can estimate channel state of the neighboring cell with higher accuracy by using a CSI-RS of the neighboring cell received in the muted REs.
