Abstract:
1. A method for transmitting an acknowledgement/negative-acknowledgement (ACK/NACK) signal from a user equipment in a wireless communication system, the method comprising: bundling a plurality of ACK/NACK signals in one ACK/NACK state information; allocating a first region of one control channel resource to a channel quality information (CQI) signal; allocating a second region of the one control channel resource to the one ACK/NACK state information; transmitting the one ACK/NACK state information and the CQI signal to a base station using the one control channel resource; and allocating an additional control channel resource to the one ACK/NACK state information when a size of the one ACK/NACK state information is greater than a size of the second region, wherein the additional control channel resource is used to transmit a number of decoded component carriers, wherein the number of decoded component carriers is indicated by using Quadrature Phase Shift Keying (QPSK) modulation and a Discontinuous Transmission (DTX) mode, and wherein an allocated location of the one ACK/NACK state information is indicated explicitly in accordance with a spatial region for modulation.
