Abstract: Measuring a Channel State Information-Reference Signal (CSI-RS) according to configuration information of the CSI-RS, to acquire a downlink channel transport matrix. Determining a Channel Quality Indicator (CQI) of a frequency domain reporting unit, according to a number of CSI-RS ports and the corresponding transmission scheme of a Physical Downlink Shared Channel (PDSCH) used when determining the CQI, and the downlink channel transport matrix being acquired by a measurement, Reporting the determined CQI to a network side.
