Patent ID: 8693414

Claim:
A multi-user (MU) transmission method for a multiple input multiple output (MIMO) transmission system comprising a first station and a plurality of second stations, the MU transmission method comprising: The first station scheduling a first group of stations of the plurality of second stations in a first transmission time interval according to channel conditions of a plurality of channels corresponding to the plurality of second stations; and the first station performing simultaneous transmission to the first group of stations in the first transmission time interval; wherein the step of the first station scheduling the first group of stations comprises: building a composite channel of the plurality of channels corresponding to the plurality of second stations; performing LQ decomposition on the composite channel, to generate an L matrix and an Q matrix, wherein X=LQ, X denotes the composite channel, L denotes the L matrix, Q denotes the Q matrix, and QQ T =I; and deciding the first group of stations in the first transmission interval according to the L matrix.
