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.

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 indicating PHICH duration of a subframe;
- receiving enhanced-physical downlink control channel (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, and
- wherein, in the subframe, the starting OFDM symbol of the E-PDCCH indicated by the E-PDCCH information is configured after the PHICH duration indicated by the PHICH information.
A user equipment (UE), the UE comprising:
- a radio frequency (RF) unit that transmits and receives a radio signal;
- and
- a processor operatively coupled to the RF unit,
- wherein the processor:
- receives physical hybrid-ARQ indicator channel (PHICH) information indicating PHICH duration of a subframe;
- receives enhanced-physical downlink control channel (E-PDCCH) information indicating a starting orthogonal frequency division multiplexing (01-DM) 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 indicated by the E-PDCCH information is configured after the PHICH duration indicated by the PHICH information.
