Methods and apparatus for providing feedback by the UE is provided. Method is a channel matrix estimated based on the second set of CSI-RS of a first set and receiving a second set of CSI-RS and the CSI-RS a first set of received power and the CSI-RS of the and calculating a CQI using includes the step of sending a feedback based on the calculated CQI. How the step of measuring the signals received from a plurality of CSI-RS port (port) and; Calculating a CQI value for each of the application (application) of precoding matrices for each selected combination of the CSI-RS ports and; The process of SPN, SPI, PMI and RI to select the highest CQI calculation of the calculated values and the CQI; It comprises the step of transmitting the SPI, the highest CQI value, the PMI and the feedback indicating at least one of the SPN or RI.
