Abstract:
Single user and multiuser MIMO transmission in a cellular network may be performed by a base station (eNB) transmitting either one or two transmission layers. A user equipment (UE) receives a reference symbol from the base station. The UE processes the reference symbol with one or more of a plurality of preceding matrices to form a plurality of channel quality indices (CQI). The UE provides feedback to the eNB comprising one or more feedback CQI selected from the plurality of CQI and one or more preceding matrix indicators (PMI) identifying the one or more preceding matrices used to form each of the one or more feedback CQIs, wherein at least two PMI are included in the feedback.
