Abstract
The present invention discloses a method and an apparatus for modifying a channel quality indication (CQI). This method may comprise: calculating a scaling factor for the channel quality indication based on uplink channel information and an antenna virtualization pre-coding scheme; and modifying the channel quality indication reported by user equipment by using the scaling factor. According to the technical solutions of the present invention, the antenna virtualization factor is considered in performing CQI modification and. Thus, this solution can overcome the problem of CQI mismatch, enhance the completeness and accuracy of CQI feedback, and improve the cell throughput performance and frequency utilization.
