Abstract: Various communication systems may benefit from feedback related to communication conditions. For example, certainly wireless communication systems may benefit from channel state information acquisition and feedback, particularly in connection with, for example, full dimension multiple input multiple output. A method can include configuring, at a base station, a plurality of reference signals as sampling points for channel state information. The method can also include restoring channel state information from implicit feedback information from a user equipment based on the sampling points. The method can further include selecting a precoder based on channel state information for a specific user equipment.
