    Abstract: A method and apparatus are provided for transmitting and receiving Downlink Control Information (DCI) in a wireless communication system. A method includes generating downlink control information including an antenna port indicator comprising antenna port information and scrambling identity information; and transmitting, to a terminal, the downlink control information and data associated with the downlink control information. The scrambling identity information indicates one of two scrambling sequences, if a number of antenna ports indicated by the antenna port information is one and one transport block is enabled.

    Abstract: The present invention relates to a method and device for transmitting and receiving CSI (Channel State Information). A CSI transmission method at a CoMP (Coordinated Multi-Point) device includes steps of receiving a CSI-RS (Reference Signal) from a plurality of transmission points, acquiring an optimal phase difference value causing an optimal channel quality between the plurality of transmission points, based on the CSI-RS, acquiring a CQI (Channel Quality Indicator), based on the optimal phase difference value, and transmitting the CSI including the CQI. According to an embodiment of the present invention, efficient CSI transmission/reception method and device can be provided in a CoMP system.
