Abstract:
1. A method for acquiring, by a user equipment, a physical uplink control channel (PUCCH) resource index in a wireless communication system, the method comprising: acquiring a PUCCH resource index indicating a first dynamic PUCCH region corresponding to an enhanced physical downlink control channel (e-PDCCH); and transmitting an acknowledgement/non-acknowledgement (ACK/NACK) signal to a base station based on the acquired PUCCH resource index, wherein the PUCCH resource index is acquired based on the smallest control channel element (CCE) index to which the e-PDCCH is allocated, and wherein the first dynamic PUCCH region corresponding to the e-PDCCH is not overlapped with a second dynamic PUCCH region corresponding to a PDCCH.
