Title:
METHOD AND APPARATUS FOR TRANSMITTING UPLINK CONTROL INFORMATION IN A WIRELESS COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2012/015212
Kind Code:
A2
Abstract:
The present invention relates to a method for a terminal, in which a plurality of serving cells is established, to transmit uplink control information in a wireless communication system. The method comprises the following steps: receiving at least one physical downlink control channel (PDCCH) via a first serving cell from among the plurality of serving cells in a first subframe; receiving at least one physical downlink shared channel (PDSCH) via at least one serving cell from among the plurality of serving cells in the first subframe based on said at least one PDCCH; and transmitting, in a second subframe, an acknowledgement/non-acknowledgement (ACK/NACK) which indicates whether or not a demodulation for said at least one PDSCH has succeeded. The ACK/NACK is transmitted using a first resource in the second subframe if said at least one PDSCH is received through only the first serving cell, and transmitted using a second resource in the second subframe if said at least one PDSCH is received through two or more serving cells from among the plurality of serving cells. The first resource is dynamically allocated through the PDCCH which schedules the first serving cell, and the second resource is designated in advance.
