摘要：
A method for reporting uplink control information (UCI) on a user equipment (UE) is described. A first precoding matrix indicator (PMI) corresponding to a multiple-user multiple-input and multiple-output (MU-MIMO) downlink transmission is generated using a first codebook set. A second PMI corresponding to the MU-MIMO downlink transmission is generated using a second codebook set. The first PMI and the second PMI are sent to an eNode B in a channel state information (CSI) report.
