Method and apparatus for controlling uplink control information transmission in wireless communication system providing widebandwidth services via carrier aggregation

A method performed by a base station in a wireless communication system, the method comprising:

• transmitting, to a terminal, a plurality of offset parameters;
• and
• receiving uplink control information (UCI) on a physical uplink shared channel (PUSCH) based on a number of coded modulation symbols from the terminal,
• wherein an offset associated with the PUSCH is identified based on a number of bits of hybrid automatic repeat request (HARQ) acknowledgement (ACK) information, the offset corresponds to at least one of the plurality of the offset parameters, and the number of the coded modulation symbols is identified based on the identified offset associated with the PUSCH.

A terminal in a wireless communication system, the terminal comprising:

• a transceiver;
• and
• a control unit configured to control to:
• receive a plurality of offset parameters from a base station via the transceiver,
• identify an offset associated with a physical uplink shared channel (PUSCH) based on a number of bits of hybrid automatic repeat request (HARQ) acknowledgement (ACK) information, the offset corresponding to at least one of the plurality of the offset parameters,
• identifying a number of coded modulation symbols based on the identified the offset associated with the PUSCH, and
• transmit, to the base station via the transceiver, uplink control information (UCI) on the PUSCH based on the identified number of the coded modulation symbols.
