TILBAGEKOBLING AF FORKODNINGSSTYRINGSINDIKATION (PCI) OG KANALKVALITETSINDIKATION (CQI) I ET TRÅDLØST KOMMUNIKATIONSSYSTEM

摘要

A method comprising determining precoding control indication (PCI) for data transmission from a transmitter (110) to a receiver (120); determining channel quality indication (CQI) for the data transmission, wherein the determining the CQI for the data transmission comprises: determining one CQI value for one transport block when one transport block is used for the data transmission, and determining two CQI values for two transport blocks when two transport blocks are used for the data transmission; forming a report based on the PCI and the CQI; sending the report to the transmitter (110); and characterized by relating the size and number of the CQI and a rank for the data transmission.
