1. A method for transmitting, by a user equipment, an uplink control signal in a wireless communication system, wherein the wireless communication system uses a time division duplex (TDD) scheme, the method comprising:
- receiving a first set of codewords through a first physical downlink shared channel (PDSCH), indicated by a first physical downlink control channel (PDCCH), on a first downlink (DL) carrier in carrier aggregation;
receiving a second set of codewords through a second PDSCH, indicated by a second PDCCH, on a second DL carrier in carrier aggregation;
obtaining a first resource based on the first PDCCH;
obtaining a second resource based on the second PDCCH; and
transmitting an uplink control signal on a single uplink (UL) carrier using at least one of the first resource and the second resource,wherein the uplink control signal is based on first acknowledgement (ACK)/non-acknowledgement (NACK) information for the first set of codewords and second ACK/NACK information for the second set of codewords.

Abstract
The present invention provides a method and an apparatus for the transmission of control signal in a radio communication system. The method includes the steps of processing first control information on the basis of a first resource index to create a first control signal, processing second control information on the basis of a second resource index to create a second control signal, and transmitting the first control signal and the second control signal.

10. A user equipment in a wireless communication system, wherein the wireless communication system uses a time division duplex (TDD) scheme, the user equipment comprising:
-
a radio frequency (RF) unit for transmitting or receiving a radio signal; and a processor coupled to the RF unit, and configured to; receive a first set of codewords through a first physical downlink shared channel (PDSCH), indicated by a first physical downlink control channel (PDCCH), on a first downlink (DL) carrier in carrier aggregation; receive a second set of codewords through a second PDSCH, indicated by a second PDCCH, on a second DL carrier in carrier aggregation; obtain a first resource based on the first PDCCH; obtain a second resource based on the second PDCCH; and transmit an uplink control signal on a single uplink (UL) carrier using at least one of the first resource and the second resource, wherein the uplink control signal is based on first acknowledgement (ACK)/non-acknowledgement (NACK) information for the first set of codewords and second ACK/NACK information for the second set of codewords. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
