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.

Abstract: A method and apparatus can be configured to receive a first scheduling request. The first scheduling request corresponds to a request for a first access point to process data. The method can also include transmitting a second scheduling request. The second scheduling request corresponds to a request to transmit data to a second access point. The transmitting the second scheduling request comprises transmitting the second scheduling request before the data is processed at the first access point.
