摘要： An electronic device in a wireless communication system, and a wireless communication method. The electronic device includes one or more processing circuits, and is configured to: respond to a measurement instruction from a base station in a wireless communication system, and separately measure channel state information reference signals (CSI-RSs) on one or more antenna ports; and generate feedback information according to the measurement result, so that the base station selects, from the one or more antenna ports, an antenna port used for transmitting to the CSI-RSs to the electronic device, the feedback information including occupation information of occupation condition of each of the one or more antenna ports. Port selection for CSI-RSs can be implemented, beamforming CSI-RS interference between cells and within a cell can be reduced, and system performance can be improved only requiring very low signaling overheads.
