Abstract
Embodiments of this application provide a MU-MIMO data transmission method, to implement pairing scheduling on UE and improve resource usage. The method includes: obtaining, by a base station, a first precoding matrix indicator PMI of first user equipment UE, where a first rank of the first UE is 1; obtaining, by the base station, a second PMI of second UE, where a second rank of the second UE is 1, and a weighted value corresponding to the first PMI and a weighted value corresponding to the second PMI form a weighted value corresponding to a third PMI whose rank is 2; and separately performing, by the base station by using the third PMI and a same time-frequency resource, data transmission with the first UE and the second UE that are paired, where a pairing gain of the first UE and the second UE is greater than a preset threshold.
