Abstract: A method for efficiently transmitting and receiving downlink control information is disclosed. The method includes, at a base station, receiving feedback information including a precoding matrix index (PMI) from a user equipment (UE) and transmitting precoding information having a predetermined bit number according to the number of antenna ports and a transmission mode of the base station. The precoding information of a predetermined transmission mode in the precoding information includes confirmation information indicating that the base station uses a PMI which is recently received from the UE.

Abstract: A technique for receiving and transmitting downlink reference signals is disclosed. When transmitting downlink data demodulation reference signals (DMRS) (or reference signals for downlink data demodulation) by using two or more layers, the DMRS of each layer may be multiplexed by using a code division multiplexing method and then transmitted. The DMRS for each of the two or more layers may be used for one user equipment or for two or more user equipments. And, downlink control signals for transmitting and receiving such DMRS may be configured to have the same format regardless of a single-user mode (or SU-MIMO mode) or a multi-user mode (or MU-MIMO mode), thereby being used.

Abstract: According to one aspect of the present invention, antennas or antenna nodes spaced away from each other by a predetermined distance or more are configured to be able to transmit control information of mutually different user equipment groups, thereby increasing the efficiency in the operation of control channels. In addition, according to another aspect of the present invention, a resource region for transmitting control information for an improved user equipment, which is a target of a multi-node cooperative transmission, is set differently from a resource region for transmitting control information for a legacy user equipment, thereby increasing the efficiency in the transmission of the control information for the improved user equipment.

Abstract: Provided are a method and an apparatus for allocating a control channel in a wireless communication system. A base station allocates an enhanced physical downlink control channel (e-PDCCH) to a localized region within a physical downlink shared channel (PDSCH) region, allocates the e-PDCCH to a distributed region within the PDSCH region, and transmits a scheduling assignment via the allocated e-PDCCH.

Abstract: A method and apparatus for transmitting a downlink signal in a multiple input multiple output (MIMO) wireless communication system is disclosed. A method for receiving a downlink signal from a base station to a user equipment in a multiple input multiple output (MIMO) system, which supports dual layer transmission based on first and second antenna ports, comprises receiving downlink control information (DCI) through a downlink control channel; and receiving downlink data through a downlink data channel, the downlink data including one or more of a first transport block and a second transport block, wherein the downlink control information includes a new data indicator (NDI) for each of the first and second transport blocks, and if the first transport block is disabled and the second transport block is enabled, the new data indicator for the first transport block indicates an antenna port through which the second transport block is received.

Abstract: The present invention relates to a method and device for decoding a channel in a wireless communication system. User equipment receives, from a base station, a candidate group of antenna ports including a plurality of antenna ports, and receives a reference signal from the base station onto enhanced physical downlink control channel (e-PDCCH) ports that correspond to all or some of the plurality of antennas in the candidate group of antenna ports. The user equipment blind-decodes the e-PDCCH configured in a physical downlink shared channel (PDSCH), on the basis of the received reference signal.
