Abstract

A method and an apparatus for supporting multiple frequency bands efficiently in a mobile communication system are provided. The method includes generating first system information including a frequency band indicator indicating a frequency band supported by the base station and an additional frequency band indicator indicating at least one frequency band supported by the base station, and broadcasting the first system information.

Claims

1. A method for supporting multiple frequency bands at a base station in a mobile communication system, the method comprising:

generating a first system information including information of at least one frequency band supported by the base station;

broadcasting the first system information;

generating a second system information including at least one additional spectrum emission value corresponding to the at least one frequency band indicated by the first system information; and

broadcasting the second system information.

2. The method of claim 1, further comprising:

receiving UpLink (UL) data, from a terminal, on a UL carrier frequency comprising a center frequency determined according to the first system information and the second system information.

3. The method of claim 1, wherein the at least one additional spectrum emission value of the second system information corresponds in sequence to the at least one frequency band supported by the base station according to the first system information.

4. A base station supporting a plurality of frequency bands in a mobile communication system, the station comprising:

a transceiver configured to transmit and receive signals to and from a terminal; and

a controller configured to control to generate a first system information including information of at least one frequency band supported by the base station, to broadcast the first system information, to generate a second system information including at least one additional spectrum emission value corresponding to the at least one frequency band indicated by the first system information, and to broadcast the second system information.

5. The base station of claim 4, wherein the transceiver is configured to receive UpLink (UL) data from the terminal on a UL carrier frequency comprising a center frequency determined according to the first system information and the second system information.

6. The base station of claim 4, wherein the at least one additional spectrum emission value of the second system information corresponds in sequence to the at least one frequency band supported by the base station according to the first system information.

7. A terminal for supporting a plurality of frequency bands in a mobile communication system, the terminal comprising:

a transceiver configured to transmit and receive signals to and from a base station; and

a controller configured to control to receive a first system information including information of at least one frequency band supported by the base station, to determine whether the frequency band indicated by the first system information include one or more frequency bands supported by the terminal, to receive, from the base station, a second system information including at least one additional spectrum emission value corresponding to the at least one frequency band indicated by the first system information, and to attempt access to the base station according to the first system information and second system information.

8. The terminal of claim 7, wherein the controller is configured to select, when the at least one frequency band indicated by the first system information includes multiple frequency bands supported by the terminal, a frequency band indicated first among the multiple frequency bands supported by the terminal included in the first system information as the frequency band to attempt access.

9. The terminal of claim 7, wherein the controller controls to determine UpLink (UL) transmission power according to the spectrum emission value corresponding to the at least one frequency band on which the terminal attempts access.

10. The terminal of claim 7, wherein the controller controls to determine an UpLink (UL) center frequency according to the first system information and second system information.

11. The terminal of claim 9, wherein the at least one additional spectrum emission value of the second system information corresponds in sequence to the at least one frequency band supported by the base station according to the first system information.

12. The terminal of claim 7, wherein the access is attempted when the at least one frequency band indicated by the first system information includes the one or more frequency bands supported by the terminal.
