1. A method of receiving acknowledgement/not-acknowledgement (ACK/NACK) of a terminal in a wireless communication system, the method comprising:
- transmitting uplink data through an uplink data channel, wherein the uplink data channel is transmitted through aggregated carriers; and
receiving ACK/NACK for the uplink data,wherein the aggregated carriers include a first band recognizable to first and second type of terminals and a second band recognizable only to the second type of terminal, andwherein resource blocks included in the first band are indexed in order using a first index, and a second index is used for indexing resource blocks included in the second band.

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.

5. A communication method of a terminal in a wireless communication system, the method comprising:
-
receiving physical hybrid-ARQ indicator channel (PHICH) information indicating a time duration of a downlink channel for receiving acknowledgement/not-acknowledgement (ACK/NACK) through system information; and receiving information indicating a starting position of an enhanced-physical downlink control channel (E-PDCCH) through a radio resource control (RRC) message, wherein an orthogonal frequency division multiplexing (OFDM) symbol at which the E-PDCCH starts is determined on the basis of a greater value between the PHICH information and information indicating a starting position of the E-PDCCH. - View Dependent Claims (6, 7)

8. A terminal comprising:
-
a radio frequency (RF) unit for transmitting and receiving a radio signal; and a processor, operatively coupled to the RF unit, that; controls the RF unit to transmit uplink data through an uplink data channel, wherein the uplink data channel is transmitted through aggregated carriers; and controls the RF unit to receive acknowledgement/not-acknowledgement (ACK/NACK) for the uplink data, wherein the aggregated carriers include a first band recognizable to first and second type of terminals and a second band recognizable only to the second type of terminal, and wherein resource blocks included in the first band are indexed in order using a first index, and a second index is used for indexing resource blocks included in the second band.
