A computing channel quality indication information terminal and a method

The present invention solves the technical problem is to provide a calculation of the channel quality of the terminal and the method information indicating the method comprising, a terminal UE performs channel measurement according to the received measurement reference signal CSI-RS or a cell-specific reference signal of the CRS, and determines the channel state CSI reference resource information and determining a channel quality indication of CQI calculation conditions, then the terminal calculates CQI value corresponding to the CSI reference resource according to the result of the determination and measurement conditions. Using the embodiment of the present invention, considered a variety of complex conditions to CQI calculation, thereby solving the conventional system in transmission mode 9 can not be obtained when using the problem of accurate channel quality indication information to improve the flexibility and performance of the system.
