CHANNEL STATE INFORMATION FEEDBACK DESIGN IN ADVANCED WIRELESS COMMUNICATION SYSTEMS |
摘要 |
Methods and apparatuses for providing feedback by a UE. A method includes receiving a first set of CSI-RS and a second set of CSI-RS, calculating a CQI using a received power of the first set of CSI-RS and a channel matrix estimated based on the second set of CSI-RS, and sending feedback based on the calculated CQI. A method includes measuring signals received on a plurality of CSI-RS ports; calculating CQI values for each of applications of precoding matrixes to each of the selected combinations of CSI-RS ports; selecting a SPN, a SPI, a PMI, and a RI that yields a highest CQI from among the calculated CQI values; and sending feedback indicating the SPI, the highest CQI value, the PMI, and at least one of the SPN or the RI. |
