METHOD AND DEVICE FOR A MULTIUSER MIMO SYSTEM TO SEND DATA

摘要

The present invention relates to the field of communications, and in particular to the technology of multiuser multiple input multiple output (MU-MIMO) data transmission. A method for a multiuser MIMO system to send data, comprising: sending a signalling frame which includes: a user group ID, K station identifiers, and virtual identification, wherein the K station identifiers correspond to K stations respectively, the virtual identification indicates a set of stations composed of any M stations in the K stations, and the user group ID corresponds to the set of stations indicated by the virtual identification; wherein K is greater than M, M is the number of stations supported by the system, and the number of virtual identifications is a natural number less than or equal to [Equation 1]; and data are sent out, and an end user in the set of M STAs indicated by the virtual identification receives data sent from the multiuser MIMO system.
