METHOD, DEVICE, AND SYSTEM FOR TRANSMITTING MU-MIMO PILOT AND DATA

摘要

Disclosed are method, device and system for transmitting MU-MIMO pilot and data. The method includes when at least two terminals transmit 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 object is to provide method, device and system for transmitting MU-MIMO pilot and data, in which a corresponding k-stream SU-MIMO pilot and data may be constructed and transmitted to at least two terminals, according to the total number of streams k that at least two terminals transmit MU-MIMO pilot and data on one same time/frequency resource, thereby effectively avoiding pseudo-orthogonality of MU-MIMO pilot.
