Method and apparatus for the transmission of a control signal in a radio communication system

摘要

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.

主权项

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.
