Abstract

The embodiments disclose a method and apparatus for performing DL MU-MIMO transmission in a radio communication network enabling MU-MIMO. The method comprises: pairing a UE with one or more other UEs for DL MU-MIMO transmission in the radio communication network; scheduling through a control channel at least one real layer and at least one virtual layer to the UE, wherein each of the at least one virtual layer is a real layer scheduled for at least one of the one or more other UEs; and performing DL transmission to the UE and the one or more other UEs on a transport channel, wherein only the at least one real layer is used for DL transmission to the UE, and each of the at least one virtual layer is used for DL transmission to at least one of the one or more other UEs.
