METHOD AND DEVICE FOR REPORTING CHANNEL QUALITY INFORMATION

摘要

A method and a device for reporting channel quality information are provided by the present invention, the method comprising that: a user equipment measures Channel-State Information-Reference Signal (CSI-RS) according to the configuration information of the CSI-RS, and acquires a downlink channel transport matrix (101); the user equipment determines the Channel Quality Indicator (CQI) of a frequency domain reporting unit according to the number of CSI-RS ports and the corresponding transmission mode of the Physical Downlink Shared Channel (PDSCH) used when determining the CQI, and to the downlink channel transport matrix acquired by measurement (102); the user equipment reports the determined CQI to the network side (103). The present invention can realize measurement and reporting of CSI-RS-based channel quality information on the basis of non-Precoding Matrix Indicator (PMI) feedback transmissions.
