Send and receive wireless communication signal method

Provides for a multi-user - multiple input multiple output (MU-MIMO) wireless communication system and method for controlling the information providing apparatus, the method comprising: receiving a plurality of resource elements including downlink control information (DCI) of (RE ), the use of the DCI, determining a plurality of downlink reference signal (DRS) can be mapped to the set of RE, RE determines that the remaining data is mapped to an RE, and the use of the MS corresponding to the pre-DRS demodulation vector encoding the data.
