Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for providing feedback by a user equipment (UE) in a wireless communication system, the method comprising: measuring signals received on a plurality of channel state information reference signal (CSI-RS) ports; selecting a plurality of combinations of the CSI-RS ports; applying a plurality of precoding matrixes to each of the selected combinations of CSI-RS ports; calculating channel quality indicator (CQI) values for each of the applications…
