Abstract

A wireless communication system is disclosed herein. More specifically, a method of transmitting control information from a user equipment in a wireless communication system is disclosed, wherein the method includes receiving a first transmission timing information for transmitting a first control information associated with one or more first downlink component carriers from a base station; determining a second transmission timing information for transmitting a second control information associated with one or more second downlink component carrier by using the first transmission timing information and an additional transmission timing information; and transmitting control information on the one or more second downlink component carriers in dependence upon the second transmission timing information to the base station.

Claims

1. A method of transmitting control information from a user equipment in a wireless communication system, the method comprising:

receiving a first transmission timing information for transmitting a first control information associated with one or more first downlink component carriers from a base station;

determining a second transmission timing information for transmitting a second control information associated with one or more second downlink component carriers by using the first transmission timing information and an additional transmission timing information; and

transmitting control information on the one or more second downlink component carriers in dependence upon the second transmission timing information to the base station.

2. The method of claim 1, wherein the first transmission timing information includes a period and an offset for transmitting channel information on the one or more first downlink component carriers.

3. The method of claim 1, wherein the second transmission timing information is determined by modifying at least one of the period and the offset included in the first transmission timing information based upon the additional transmission timing information.

4. The method of claim 1, wherein the additional transmission timing information indicates a relative value for a specific parameter or an absolute value for the specific parameter, among a plurality of parameters configuring the first transmission timing information.

5. The method of claim 1, wherein the additional transmission timing information is obtained by using a parameter associated with the one or more second downlink component carriers.

6. The method of claim 1, wherein the second transmission timing information is determined so that the first control information and the second control information are prevented from being transmitted simultaneously.

7. The method of claim 1, wherein the first control information and the second control information are transmitted to the base station through the same uplink component carrier.

8. A user equipment of a wireless communication system, the user equipment comprising:

a radio frequency (RF) unit being configured to transmit and receive wireless signals to and from a base station;

a memory storing information being transmitted and received to and from the base station and parameters required for performing operations of the user equipment; and

a processor connected to the RF unit and the memory, and being configured to control the RF unit and the memory, so as to operate the user equipment, and wherein the processor performs a method for transmitting control information comprising;

receiving a first transmission timing information for transmitting a first control information associated with one or more first downlink component carriers from a base station;

determining a second transmission timing information for transmitting a second control information associated with one or more second downlink component carriers by using the first transmission timing information and an additional transmission timing information; and

transmitting control information on the one or more second downlink component carriers in dependence upon the second transmission timing information to the base station.

9. The user equipment of claim 8, wherein the first transmission timing information includes a period and an offset for transmitting channel information on the one or more first downlink component carriers.

10. The user equipment of claim 8, wherein the second transmission timing information is determined by modifying at least one of a period and an offset included in the first transmission timing information based upon the additional transmission timing information.

11. The user equipment of claim 8, wherein the additional transmission timing information indicates a relative value for a specific parameter or an absolute value for the specific parameter, among a plurality of parameters configuring the first transmission timing information.

12. The user equipment of claim 8, wherein the additional transmission timing information is obtained by using a parameter associated with the one or more second downlink component carriers.

13. The user equipment of claim 8, wherein the second transmission timing information is determined so that the first control information and the second control information are prevented from being transmitted simultaneously.

14. The user equipment of claim 8, wherein the first control information and the second control information are transmitted to the base station through the same uplink component carrier.
