Abstract

A system and a method that reports capability information regarding a dual mode User Equipment (UE) are provided. The UE supports Frequency Division Duplex (FDD) and Time Division Duplex (TDD). The UE capability transmitting method includes receiving a message requesting UE capability information from an evolved Node B (eNB), generating first capability information and second capability information according to the UE capability information requesting message, and transmitting UE capability information including the first and second capability information to the eNB. The first capability information comprises FDD capability information applicable to an FDD mode or TDD capability information applicable to a TDD mode. The second capability information comprises capability information applicable to both the FDD mode and the TDD mode. The system and method can allow a dual mode UE to efficiently report its capability information.

Claims

1. A method for transmitting capability information by a terminal in a wireless communication system, the method comprising:

receiving, from a base station, a first message requesting a radio access capability of the terminal;

identifying first capability information by considering both of a frequency division duplex (FDD) mode and a time division duplex (TDD) mode;

identifying second capability information by considering either the FDD mode or the TDD mode; and

transmitting, to the base station, a second message including at least one of the first capability information and the second capability information.

2. The method of claim 1, further comprising determining whether the first capability information and the second capability information are different,

wherein the second message is generated based on a result of the determination.

3. The method of claim 2, wherein the second message includes the first capability information and the second capability information, in case that the first capability information and the second capability information are different.

4. The method of claim 2, wherein the second message includes the first capability information or the second capability information, in case that the first capability information and the second capability information are same.

5. The method of claim 1,

wherein the first message comprises information indicating a radio access technology (RAT) type,

wherein the first capability information and the second capability information are identified for the RAT type, and

wherein the second message comprises information indicating the RAT type.

6. A method of receiving capability information by a base station in a wireless communication system, the method comprising:

transmitting, to a terminal, a first message requesting a radio access capability of the terminal; and

receiving, from the terminal, a second message including at least one of first capability information and second capability information,

wherein the first capability information is identified by considering both of a frequency division duplex (FDD) mode and a time division duplex (TDD) mode, and

wherein the second capability information is identified by considering either the FDD mode or the TDD mode.

7. The method of claim 6, wherein the second message is generated based on a result of a determining whether the first capability information and the second capability information are different.

8. The method of claim 7, wherein the second message includes the first capability information and the second capability information, in case that the first capability information and the second capability information are different.

9. The method of claim 7, wherein the second message includes the first capability information or the second capability information, in case that the first capability information and the second capability information are same.

10. The method of claim 6,

wherein the first message comprises information indicating a radio access technology (RAT) type,

wherein the first capability information and the second capability information are identified for the RAT type, and

wherein the second message comprises information indicating the RAT type.

11. A terminal for transmitting capability information in a wireless communication system, the terminal comprising:

a transceiver configured to transmit and receive a signal; and

a controller configured to;

receive, from a base station, a first message requesting a radio access capability of the terminal,

identify first capability information by considering both of a frequency division duplex (FDD) mode and a time division duplex (TDD) mode,

identify second capability information by considering either the FDD mode or the TDD mode, and

transmit, to the base station, a second message including at least one of the first capability information and the second capability information.

12. The terminal of claim 11,

wherein the controller is further configured to determine whether the first capability information and the second capability information are different, and

wherein the second message is generated based on a result of the determination.

13. The terminal of claim 12, wherein the second message includes the first capability information and the second capability information, in case that the first capability information and the second capability information are different.

14. The terminal of claim 12, wherein the second message includes the first capability information or the second capability information, in case that the first capability information and the second capability information are same.

15. The terminal of claim 11,

wherein the first message comprises information indicating a radio access technology (RAT) type,

wherein the first capability information and the second capability information are identified for the RAT type, and

wherein the second message comprises information indicating the RAT type.

16. A base station of receiving capability information in a wireless communication system, the base station comprising:

a transceiver configured to transmit and receive a signal; and

a controller configured to;

transmit, to a terminal, a first message requesting a radio access capability of the terminal, and

receive, from the terminal, a second message including at least one of first capability information and second capability information,

wherein the first capability information is identified by considering both of a frequency division duplex (FDD) mode and a time division duplex (TDD) mode, and

wherein the second capability information is identified by considering either the FDD mode or the TDD mode.

17. The base station of claim 16, wherein the second message is generated based on a result of a determining whether the first capability information and the second capability information are different.

18. The base station of claim 17, wherein the second message includes the first capability information and the second capability information, in case that the first capability information and the second capability information are different.

19. The base station of claim 17, wherein the second message includes the first capability information or the second capability information, in case that the first capability information and the second capability information are same.

20. The base station of claim 16,

wherein the first message comprises information indicating a radio access technology (RAT) type,

wherein the first capability information and the second capability information are identified for the RAT type, and

wherein the second message comprises information indicating the RAT type.
