Patent ID: 8842609

Claim:
A method for allowing a user equipment to transmit ACK/NACK information in a multicarrier-supporting wireless communication system, the method comprising: generating individual ACK/NACK information in association with individual codewords received from a base station through N carriers (where N≧2) in M downlink subframes (where M≧2), wherein a number of bits of the individual ACK/NACK information in association with the individual codewords received through the N carriers in the M downlink subframes exceeds a predetermined number of bits; performing spatial bundling to individual ACK/NACK information in association with individual codewords received through M+C−9 carriers among the N carriers and in the M downlink subframes; and transmitting the spatially-bundled ACK/NACK information and the remaining individual ACK/NACK information without applying the spatial bundling, to the base station through one uplink subframe, wherein C is a total sum of maximum numbers of codewords configured in each of the N carriers in one downlink subframe.
