Method and apparatus for transmitting acknowledgement in wireless communication system
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.
