Abstract: A method is provided for generating Acknowledgement/Negative Acknowledgement (ACK/NACK) information by a user equipment (UE) in a wireless communication system supporting carrier aggregation. The UE receives, from a base station (BS), a plurality of codewords through a plurality of downlink carriers. Each of the plurality of downlink carriers support one or more codewords according to a transmission mode. The transmission mode is independently configured per each of the plurality of downlink carriers. The UE determines a total number of ACK/NACK bits, and generates a sequence of the ACK/NACK bits according to the total number of the ACK/NACK bits. The UE determines the total number of ACK/NACK bits based on a total number of the plurality of downlink carriers and a type of each transmission mode independently configured per each of the plurality of downlink carriers.

Abstract: A method and a base station for receiving uplink control signals in a wireless communication system are described. The base station receives a first uplink control channel in a mixed resource block from a first user equipment. The mixed resource block includes a plurality of subcarriers. The base station receives a second uplink control channel in the mixed resource block from a second user equipment. The first uplink control channel is identified by a first cyclic shift value. The second uplink control channel is identified by a second cyclic shift value that is different from the first cyclic shift value. The first uplink control channel carries a Hybrid Automatic Repeat Request (HARQ) acknowledgement/negative acknowledgement (ACK/NACK) of the first user equipment. The second uplink control channel carries a channel quality indicator (CQI) for the second user equipment and a HARQ ACK/NACK of the second user equipment.
