Abstract
An apparatus and a method for transmitting and receiving control information in a Multiple Input Multiple Output (MIMO) system are provided. A method of a base station for transmitting control information to a terminal in the MIMO system includes transmitting first control information for every transmission mode except for a Multiple-User (MU)-MIMO mode, to the terminal over a control channel of a subframe, and transmitting second control information for the MU-MIMO mode to the terminal over a data channel of the subframe.
Claims24
A method of a base station for transmitting control information to a terminal in a Multiple Input Multiple Output (MIMO) system, the method comprising:
- transmitting first control information for every transmission mode except for a Multiple-User (MU)-MIMO mode, to the terminal over a control channel of a subframe;
- and
- transmitting second control information for the MU-MIMO mode to the terminal over a data channel of the subframe.
A method of a terminal for receiving control information from a base station in a Multiple Input Multiple Output (MIMO) system, the method comprising:
- receiving first control information for every transmission mode except for a Multiple-User (MU)-MIMO mode, from the base station over a control channel of a subframe;
- and
- receiving second control information for the MU-MIMO mode from the base station over a data channel of the subframe.
An apparatus of a base station for transmitting control information to a terminal in a Multiple Input Multiple Output (MIMO) system, the apparatus comprising:
- a first control information generator for generating first control information for every transmission mode except for a Multiple-User (MU)-MIMO mode;
- a second control information generator for generating second control information for the MU-MIMO mode;
- and
- a transmit signal processor for transmitting the generated first control information to the terminal over a control channel of a subframe, and for transmitting the generated second control information to the terminal over a data channel of the subframe.
An apparatus of a terminal for receiving control information from a base station in a Multiple Input Multiple Output (MIMO) system, the apparatus comprising:
- a receive signal processor for receiving first control information for every transmission mode except for a Multiple-User (MU)-MIMO mode, from the base station over a control channel of a subframe, and for receiving second control information for the MU-MIMO mode from the base station over a data channel of the subframe;
- a first control information checker for checking the first control information for every transmission mode except for the MU-MIMO mode;
- and
- a second control information checker for checking the second control information for the MU-MIMO mode.
