Method for transmitting CSI-RS and base station
Methods for transmitting a channel state information-reference signals (CSI-RS) and a base station are provided, where the example method includes aggregating, by the base station, first configuration modes of K CSI-RSs to form a second configuration mode of the CSI-RSs, where K is an integer greater than or equal to 2, where each of the first configuration modes is a configuration mode of X ports, where a value of X is 2, 4, or 8, and where the first configuration mode includes a position of a resource element corresponding to each of the X ports. The second configuration mode is a configuration mode of X*K ports, and the second configuration mode includes a position of a resource element corresponding to each of the X*K ports. The method further includes sending, by the base station, a CSI-RS to user equipment UE using the second configuration mode of the CSI-RSs.
