FIELD: radio engineering, communication.
SUBSTANCE: invention relates to multi-user multiple input multiple output (MU-MIMO) wireless communication systems. An aspect of the invention consists in improving an apparatus and a method for providing and using control information in a mobile communication system. The invention particularly discloses a method for outputting control information in MU-MIMO wireless communication systems, which includes receiving a plurality of resource elements (RE) including downlink control information (DCI), determining, using the DCI, a set of RE to which a plurality of downlink reference signals (DRS) may be mapped, determining remaining RE as RE to which data are mapped, and demodulating the data using a precoding vector of a DRS corresponding to the MS.
EFFECT: improved communication.
