Downlink control information (DCI) indication method and apparatus thereof

The invention discloses a downlink control information (DCI) indication method and an apparatus thereof. The method and the apparatus can be used to support multilayer transmission based on a UE specific reference signal (URS). The UE generates DCI. The DCI comprises an indication signaling. The indication signaling is used to indicate antenna port information and combined coding information of a URS correlation parameter. Antenna port information dereferencing comprises one of the following antenna port sets or any arbitrary combination: a port 7 and the port 9; the port 7 and the port 10; the port 8 and the port 9; the port 8 and the port 10; the port 9 and the port 10; the port 7, the port 9 and the port 10; the port 8, the port 9 and the port 10; the port 7, the port 8 and the port 9; the port 7, the port 8 and the port 10. In the invention, the new indication signaling is added in a DCI format and is used to indicate different combined coding parameters when an enabled transmission block quantity is different. Interference between ePDCCH and a cell can be eliminated or can be coordinated.
