Abstract: A method and device for feeding back downlink channel feedback information, and a method and device for user pairing. The method for feeding back downlink channel feedback information includes: calculating the multi-user channel quality indication error of a user, which error is used to reflect the difference in channel quality indication between the situation of multi-user multiple input multiple output transmission and the situation of single user multiple input multiple output transmission; adding the multi-user channel quality indication error into the downlink channel feedback information which includes a pre-coding matrix indication and a channel quality indication, and feeding the same back to a base station for scheduling. Therefore, the bit error rate of demodulation in the MIMO system can be reduced and the system performance can be improved.
