Abstract
Disclosed are a method, device and system for transmitting a Multi-user Multiple-Input-Multiple-Output (MU-MIMO) pilot and data. The method includes: when at least two terminals transmit a MU-MIMO pilot and data on one same time/frequency resource, constructing a k-stream SU-MIMO pilot and data; based on the configuration mode of the k-stream SU-MIMO pilot, modifying demodulation pilot port parameters of the at least two terminals; and based on the transmission mode of the k-stream SU-MIMO pilot and data, transmitting the k-stream SU-MIMO pilot and data to the at least two terminals, respectively. Further disclosed are a device and system for transmitting a MU-MIMO pilot and data.
