A method for operating a reception point includes receiving a plurality of first directional reference signals spanning a first plane, selecting at least one first directional reference signal from the plurality of received first directional reference signals that meets a first selection criterion, sending a first feedback indicating the selected at least one first directional reference signal, receiving a plurality of second directional reference signals spanning a second plane oriented in accordance with the selected at least one first directional reference signal, selecting at least one second directional reference signal from the plurality of received second directional reference signals that meet a second selection criterion, and sending a second feedback indicating the selected at least one second directional reference signals. |
