摘要：
An electronic device for a base station in a wireless communication system including processing circuitry configured to indicate a user equipment to report a first type of channel statement information based on a reference signal for the first type of channel statement information, wherein the base station serves the user equipment in a way of SU-MIMO, make a determination that a second type of channel statement information is required in a case that the base station changes the way serving the user equipment from SU-MIMO to MU-MIMO, and notify the user equipment to report the second type of channel statement information based on a reference signal for the second type of channel statement information.
