Abstract:
Methods and apparatuses are provided for receiving control information by a terminal. A control channel message is received on a control channel. Control information comprising a transmission rank and precoding matrix information is extracted from the control channel message if a common pilot is used for data demodulation. The control information comprising the transmission rank and information about a dedicated pilot is extracted from the control channel message if the dedicated pilot is used for the data demodulation.
