发明名称 Channel state information feedback for enhanced downlink multiple input-multiple output operation
摘要 In accordance with the exemplary embodiments of the invention there is deriving multiple input-multiple output feedback information using a set of precoding matrices associated with at least one precoding codebook, signaling, in a first plurality of resource elements, channel state information associated with a first precoding matrix indicator of the set of precoding matrices jointly with a transmission rank, and signaling separately, in a second plurality of resource elements, channel state information associated with a second precoding matrix indicator of the set of precoding matrices. In addition, there is receiving signaling in a first plurality of resource elements of channel state information associated with a first precoding matrix indicator of a set of precoding matrices jointly with a transmission rank, receiving signaling separately in a second plurality of resource elements of channel state information associated with a second precoding matrix indicator of the set of precoding matrices, and controlling a downlink multiple input-multiple output transmission in accordance with the received signaling.
