1. A method of communication by a user equipment (UE) in a wireless communication system, the method comprising:
- receiving physical hybrid-ARQ indicator channel (PHICH) information indicating PHICH duration of a subframe; and
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 via a radio resource control (RRC) message,wherein the starting OFDM symbol of the E-PDCCH indicated by the E-PDCCH information in the subframe is configured after the PHICH duration indicated by the PHICH information in the subframe.

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.
