Claim
1. A method for transmitting data and control information in a wireless communication system, the method comprising the steps of:
generating the control information;
when the control information and information data to be transmitted have occurred in a same Transmission Time Interval (TTI), determining a number of symbols for transmission of the control information in consideration of a quantity of the information data to be transmitted;
multiplexing the information data and the control information; and
transmitting the multiplexed information data and control information.
2. The method of claim 1, wherein the control information is Hybrid Automatic Repeat reQuest (HARQ) feedback information.
3. The method of claim 1, wherein the number of symbols for transmission of the control information can be determined by considering a quantity of scheduled resources with the quantity of information data to be transmitted.
4. The method of claim 1, wherein the multiplexed information data and control information are transmitted on scheduled resources for the information data.
5. The method of claim 4, wherein the information data is transmitted by using remaining resources except for the control information.
6. The method of claim 1, wherein, when only the control information is transmitted in the TTI, the control information is transmitted on preconfigured resources for the control information.
7. The method of claim 1, wherein the control information is multiplexed with the information data before modulation.
8. The method of claim 1, wherein the control information is multiplexed with a reference signal to be transmitted for demodulation of the control information and the information data based on a Time Division Multiplexing (TDM) method.
9. The method of claim 1, wherein, when the control information is transmitted with the information data in the same TTI, the information data and the control information are modulated by a same modulation scheme.
10. A User Equipment (UE) apparatus for transmitting data and control information in a wireless communication system, the UE apparatus comprising:
a control information generator for generating the control information;
a control channel controller for determining a number of symbols for transmission of the control information in consideration of a quantity of information data to be transmitted, when the control information and the information data to be transmitted have occurred in a same Transmission Time Interval (TTI);
a multiplexer for multiplexing the information data and the control information; and
a transmitting unit for transmitting the multiplexed information data and control information.
11. The UE apparatus of claim 10, wherein the control information is Hybrid Automatic Repeat reQuest (HARQ) feedback information.
12. The UE apparatus of claim 10, wherein the control channel controller determines the number of symbols for transmission of the control information in consideration of a quantity of scheduled resources with the quantity of information data to be transmitted.
13. The UE apparatus of claim 10, wherein the transmitting unit transmits the multiplexed information data and control information on scheduled resources for the information data.
14. The UE apparatus of claim 13, wherein the information data is transmitted by using remaining resources except for the control information.
15. The UE apparatus of claim 10, wherein the control information is transmitted on preconfigured resources for the control information when only the control information is transmitted in the TTI.
16. The UE apparatus of claim 10, wherein the multiplexer multiplexes the information data and the control information before modulation.
17. The UE apparatus of claim 10, wherein the multiplexer multiplexes the control information and a reference signal to be transmitted for demodulation of the control information and the information data based on a Time Division Multiplexing (TDM) method.
18. The UE apparatus of claim 10, further comprising a modulator for modulating the information data and the control information by a same modulation scheme when the control information is transmitted with the information data in the same TTI.
