Claim:
1. A method for transmitting Multi-User Multiple-Input-Multiple-Output (MU-MIMO) pilot and data, comprising: constructing, by a construction module of an apparatus for transmitting the MU-MIMO pilot and data, k streams of Single-User Multiple-Input-Multiple-Output (SU-MIMO) pilot and data when at least two terminals perform transmission of the MU-MIMO pilot and data on a same time and frequency resource; modifying, by a modifying module of the apparatus, parameters of demodulation pilot ports of the at least two terminals according to the k streams of the SU-MIMO pilot; and transmitting, by a transmitting module of the apparatus, the k streams of the SU-MIMO pilot and data to the at least two terminals, wherein the at least two terminals comprise a first terminal and a second terminal, the first terminal performs transmission of L and L i is a quantity of streams of the MU-MIMO pilot and data transmission performed by an ith terminal.
