A method for transmitting information, and means cqi

The embodiment of the invention provides a method and device for transmitting CQI (channel quality indicator) information, aiming to improve the calculation accuracy of the CQI information in a CoMP (coordinated multipoint transmission/reception) situation. The existing CQI information generation method can only generate the CQI information of single transmitting point, is difficult to obtain favorable multipoint coordination scheduling and precoding results and cannot accurately calculate a downlink CQI after scheduling. Moreover, by adopting the technical scheme provided by the embodiment of the invention, a terminal can obtain the CQI information of each corresponding coordinated transmitting point respectively according to a channel matrix and PMI (precoding matrix indicator) information corresponding to each coordinated transmitting point and the sum of interference and noise power beyond the measured coordinated transmitting points, and then send the CQI information of each coordinated transmitting point to a network side, thus the network side can implement more accurate scheduling and precoding, as well as link adaptation, and furthermore, the system performance can be promoted as a whole.
