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.

Abstract: A method of operating a wireless communication system (FIG. 4) is disclosed. The method includes receiving a plurality of reference signals from a respective plurality of transceivers (402). Each of the plurality of reference signals is measured to produce a respective plurality of channel state information (CSI) measurements (404). An aggregated channel quality indicator (CQI) is calculated from measuring the plurality of reference signals (406). The aggregated CQI is transmitted to at least one transceiver of the respective plurality of transceivers (408).

Abstract: A wireless transmission system included at least one user equipment and a base station. The base station is operable to form a downlink control information block, modulate the downlink control information, precode the modulated downlink control information, and transmit the precoded, modulated downlink control information on at least one demodulation reference signal antenna port to the at least one user equipment. The precoded, modulated downlink control information is mapped to a set of N1 physical resource block pairs in a subframe from an orthogonal frequency division multiplexing symbol T1 to and orthogonal frequency division multiplexing symbol T2.
