With a single precoding implemented method, apparatus, and systems mimo

The present invention is applicable to the field of communication technology, there is provided a pre-coding methods, apparatus and a MIMO system, the method comprising: receiving a plurality of channel state information sent by a user equipment; selecting from a preset number of multiple users can use the paired user equipment user multi-user MIMO pairing; the actual strategy selected precoding type set in advance, pre-encoding processing on user data of a plurality of devices according to the pre-selected type of coding, precoding code word generating multi-user MIMO ; the precoding code word precoding code word and the multi-user MIMO and the multi-user MIMO demodulation reference signal corresponding to the preset number of broadcast to a plurality of user equipments. The present invention, on the one hand so that the multi-user MIMO or cooperative multipoint transmission COMP performance is improved, on the other hand so that the pre-coding system for implementing comparatively easy to achieve multi-user MIMO or CoMP COMP.
