Patent ID: 8447339

Claim:
A multiuser multi-input multi-output scheduling method, comprising: performing multiuser scheduling at a base station by using mean channel matrixes from respective user equipments; and performing multiuser precoding at the base station by using instantaneous channel matrixes of respective user equipments selected in the multiuser scheduling; wherein the multiuser precoding includes: informing selected/active user equipments to feed back instantaneous channel matrixes; receiving the instantaneous channel matrixes fed back by the selected/active user equipments; calculating precoding matrixes for the respective selected/active user equipments based on the corresponding instantaneous channel matrixes; multiplying data vectors of the respective selected/active user equipments with the corresponding precoding matrixes to generate respective precoded messages for each selected/active user equipments; and sending the respective precoded messages to the corresponding selected/active user equipments.
