5. The method of claim 4 , wherein the primary cell is the identified serving cell, if the PUSCH is allocated to the primary cell.

6. The method of claim 4 , wherein a secondary cell with a smallest cell index among the at least one secondary cell is the identified serving cell, if the PUSCH is not allocated to the primary cell.

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

a transceiver; and

a controller configured to:

generate uplink control information (UCI) including at least one of channel quality indicator (CQI) information and hybrid automatic repeat request (HARQ) information,

identify, if the terminal is configured with a plurality of serving cells, a serving cell among the plurality of serving cells based on information on a cell index of the serving cell, and

transmit, via the transceiver, the UCI on a physical uplink shared channel (PUSCH) of the identified serving cell.

8. The terminal of claim 7 , wherein the identified serving cell has a smallest cell index among the plurality of serving cells.

9. The terminal of claim 7 , wherein the plurality of serving cells include a first cell and at least one second cell, and

wherein the first cell has a smallest cell index among the plurality of serving cells.

10. The terminal of claim 9 , wherein the first cell is a primary cell and the at least one second cell is at least one secondary cell.

11. The terminal of claim 10 , wherein the primary cell is the identified serving cell, if the PUSCH is allocated to the primary cell.

12. The terminal of claim 10 , wherein a secondary cell with a smallest cell index among the at least one secondary cell is the identified serving cell, if the PUSCH is not allocated to the primary cell.

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

receiving uplink control information (UCI) including at least one of channel quality indicator (CQI) information and hybrid automatic repeat request (HARQ) information through a serving cell of a terminal configured with a plurality of serving cells; and

decoding the UCI,

wherein the serving cell for receiving the UCI among the plurality of serving cells is determined based on information on a cell index of the serving cell.

14. The method of claim 13 , wherein the serving cell for the UCI has a smallest cell index among the plurality of serving cells.

15. The method of claim 13 , wherein the plurality of serving cells include a first cell and at least one second cell, and

wherein the first cell has a smallest cell index among the plurality of serving cells.

16. The method of claim 15 , wherein the first cell is a primary cell and the at least one second cell is at least one secondary cell.

17. The method of claim 16 , wherein the primary cell is the serving cell for the UCI, if a physical uplink shared channel (PUSCH) is allocated to the primary cell.

18. The method of claim 16 , wherein a secondary cell with a smallest cell index among the at least one secondary cell is the serving cell for the UCI, if a physical uplink shared channel (PUSCH) is not allocated to the primary cell.

19. A base station in a wireless communication system, the base station comprising:

a transceiver; and

a controller configured to:

receive uplink control information (UCI) including at least one of channel quality indicator (CQI) information and hybrid automatic repeat request (HARQ) information through a serving cell of a terminal configured with a plurality of serving cells, and

decode the UCI,

wherein the serving cell for receiving the UCI among the plurality of serving cells is determined based on information on a cell index of the serving cell.
