    Abstract: In an embodiment of the present invention, a method for transmitting a signal by a transmission point in a wireless communication system comprises the steps of generating complex modulation symbols for a terminal which is in a partially connected interference channel state; applying symbol extension to each of the complex modulation symbols, using a pre-coding matrix; and mapping the extended complex modulation symbols to resource elements, wherein the symbol extension is performed by multiplying an element of one column of the pre-coding matrix by each of the complex modulation symbols.

    Abstract: A method for operating a terminal in a carrier aggregation system and a corresponding apparatus. In the method, downlink control information (DCI) including a downlink assignment index (DAI) can be received via an enhanced physical downlink control channel (E-PDCCH). The DCI received via the E-PDCCH includes an additional field which does not exist in the DCI received via a physical downlink control channel (PDCCH). If the DAI value is larger than 1, the additional field is used in selecting one of a plurality of PUCCH resources set by the upper layer, and the selected one resource is used in transmitting ACK/NACK.

    Abstract: The method for transmitting an acknowledgement for enhanced physical downlink control channel (EPDCCH) by a terminal in a wireless communication system according to one embodiment of the present invention comprises: a step of receiving EPDCCH; and a step of determining a resource for transmitting the acknowledgement based on one or more of the values related to the enhanced control channel element (ECCE) index which is the lowest from among the indices of ECCEs used in the EPDCCH transmission, an antenna port index, and a predetermined value indicated by downlink control information. The transmitting acknowledgement method determines whether to use the predetermined value indicated by the downlink control information when the resource for transmitting the acknowledgement is determined, based on one or more of the transmitted EPDCCH type, the size of an DCI format, information related to the physical resource block (PRB) set of the transmitted EPDCCH, and the type of the signal transmitted on the PDSCH indicated by the EPDCCH.
