1. A method for performing communication in a wireless communication system, the method performed by a user equipment (UE) comprising:
- receiving physical hybrid-ARQ indicator channel (PHICH) information, the PHICH information indicating PHICH duration in a subframe;
receiving enhanced-physical downlink control channel (E-PDCCH) information the E-PDCCH information indicating a starting orthogonal frequency division multiplexing (OFDM) symbol of an E-PDCCH in the subframe; and
performing communication based on the E-PDCCH information and the PHICH information,wherein the E-PDCCH information is received via a radio resource control (RRC) message, andwherein, in the subframe, the starting OFDM symbol of the E-PDCCH is configured after an OFDM symbol indicated by the PHICH duration.

Abstract
The present invention provides a method for receiving acknowledgement/not-acknowledgement (ACK/NACK) of a terminal in a wireless communication system. The method transmits uplink data through an uplink data channel and receives ACK/NACK for the uplink data. The uplink data channel is transmitted through aggregated carriers and the aggregated carriers include a first band recognizable to first and second type terminals and a second band recognizable only to the second type terminal.

7. A user equipment (UE), the UE comprising:
-
a transceiver; and a processor operatively coupled to the transceiver, wherein the processor; controls the transceiver to receive physical hybrid-ARQ indicator channel (PHICH) information, the PHICH information indicating PHICH duration in a subframe; controls the transceiver to receive enhanced-physical downlink control channel (E-PDCCH) information, the E-PDCCH information indicating a starting orthogonal frequency division multiplexing (OFDM) symbol of an E-PDCCH in the subframe; and performs communication based on the E-PDCCH information and the PHICH information, wherein the E-PDCCH information is received via a radio resource control (RRC) message, and wherein, in the subframe, the starting OFDM symbol of the E-PDCCH is configured after an OFDM symbol indicated by the PHICH duration.
