Method and apparatus for transmitting uplink control information in multi-carrier wireless communication system
A method and apparatus are provided for transmitting Uplink Control Information (UCI) on a data channel in a multi-carrier wireless communication system. The method includes channel-coding a UCI with reference to a number of UCI bits available; dividing the channel coded UCI bits into a number of Physical Uplink Shared Channels (PUSCHs); and transmitting the UCI multiplexed with data on the individual PUSCHs.
1. A method for transmitting information by a terminal in a wireless communication system, the method comprising:
identifying uplink control information (UCI);
identifying a serving cell among a plurality of serving cells, based on information on a cell index of the serving cell; and
transmitting the UCI on a physical uplink shared channel (PUSCH) of the identified serving cell.
2. The method of claim 1 , wherein a serving cell with a smallest cell index among the plurality of serving cells is determined as the identified serving cell.
3. The method of claim 1 , wherein the plurality of serving cells includes 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.
4. The method of claim 3 , wherein the first cell is a primary cell and the at least one second cell is at least one secondary cell.
5. The method of claim 4 , wherein the identified serving cell is determined as the primary cell, if the PUSCH is allocated to the primary cell.
6. The method of claim 4 , wherein the identified serving cell is determined as a secondary cell with a smallest cell index among the at least one secondary cell, if the PUSCH is not allocated to the primary cell.
7. The method of claim 1 , wherein the UCI includes at least one of a channel quality indicator (CQI) information, and acknowledgement/negative-acknowledgement (ACK/NACK) information.
8. An apparatus of a terminal for transmitting information in a wireless communication system, the apparatus comprising:
a transceiver configured to communicate with at least one base station; and
a controller configured to control the terminal to identify uplink control information (UCI), to identify a serving cell among a plurality of serving cells, based on information on a cell index of the serving cell, and to transmit the UCI on a physical uplink shared channel (PUSCH) of the identified serving cell.
9. The apparatus of claim 8 , wherein a serving cell with a smallest cell index among the plurality of serving cells is determined as the identified serving cell.
10. The apparatus of claim 8 , wherein the plurality of serving cells include a first cell and a second cell, and
wherein the first cell has a smallest cell index among the plurality of serving cells.
11. The method of claim 10 , wherein the first cell is a primary cell and the at least one second cell is at least one secondary cell.
12. The method of claim 11 , wherein the identified serving cell is determined as the primary cell, if the PUSCH is allocated to the primary cell.
13. The method of claim 11 , wherein the identified serving cell is determined as a secondary cell with a smallest cell index among the at least one secondary cell, if the PUSCH is not allocated to the primary cell.
14. The method of claim 8 , wherein the UCI includes at least one of a channel quality indicator (CQI) information, and acknowledgement/negative-acknowledgement (ACK/NACK) information.
15. A method for receiving information by a base station in a wireless communication system, the method comprising:
receiving uplink control information (UCI) from a terminal;
extracting the UCI from a serving cell among a plurality of serving cells for the terminal; and
decoding the extracted UCI,
wherein the serving cell for the UCI is determined based on information on a cell index of the serving cell.
16. The method of claim 15 , wherein a serving cell with a smallest cell index among the plurality of serving cells is determined as the serving cell for the UCI.
17. The method of claim 15 , 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.
18. The method of claim 17 , wherein the first cell is a primary cell and the at least one second cell is at least one secondary cell.
19. The method of claim 18 , wherein the UCI is received on the primary cell, if a physical uplink shared channel (PUSCH) is allocated to the primary cell.
20. The method of claim 18 , wherein the UCI is received on a secondary cell with a smallest cell index among the at least one secondary cell, if a physical uplink shared channel (PUSCH) is not allocated to the primary cell.
21. The method of claim 15 , wherein the UCI includes at least one of a channel quality indicator (CQI) information, and acknowledgement/negative-acknowledgement (ACK/NACK) information.
22. An apparatus of a base station for receiving information in a wireless communication system, the method comprising:
a transceiver configured to communicate with a terminal; and
a controller configured to control the base station to receive uplink control information (UCI) from the terminal, to extract the UCI from a serving cell among a plurality of serving cells for the terminal, and to decode the extracted UCI,
wherein the serving cell for the UCI is determined based on information on a cell index of the serving cell.
23. The apparatus of claim 22 , wherein a serving cell with a smallest cell index among the at least one serving cell is determined as the serving cell for the UCI.
24. The apparatus of claim 22 , 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.
25. The apparatus of claim 24 , wherein the first cell is a primary cell and the at least one second cell is at least one secondary cell.
26. The apparatus of claim 25 , wherein the UCI is received on the primary cell, if a physical uplink shared channel (PUSCH) is allocated to the primary cell.
27. The apparatus of claim 25 , wherein the UCI is received on a secondary cell with a smallest cell index among the at least one secondary cell, if a physical uplink shared channel (PUSCH) is not allocated to the primary cell.
28. The method of claim 22 , wherein the UCI includes at least one of a channel quality indicator (CQI) information, and acknowledgement/negative-acknowledgement (ACK/NACK) information.
