Abstract
The present invention discloses a method and a system for transmitting data using the collaborative multiple input multiple output (MIMO) beamforming. The method comprises: selecting an MIMO mode according to channel quality information (CQI) (S502); performing the MIMO encoding on a data stream according to the selected MIMO mode, and distributing the encoded data stream to a plurality of transmitting ends which are mutual collaborative (S504); and transmitting, by the plurality of transmitting ends, the encoded data stream (S506). The present invention solves the problem in the relevant art of reducing the system performance and the flexibility, which is caused by adopting the fixed MIMO mode when the system carries out the encoding and the transmission, which is capable of improving the system performance.
