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.
Claims20
A method for supporting multiple frequency bands by a base station in a wireless communication system, the method comprising:
- generating first system information including first information indicating a first frequency band supported by a cell and a list of at least one second information indicating at least one second frequency band supported by the cell;
- transmitting the first system information to a terminal;
- generating second system information including uplink frequency information, first spectrum emission information corresponding to the first information and a list of at least one second spectrum emission information corresponding to the at least one second information;
- and
- transmitting the second system information to the terminal,
- wherein an uplink frequency offset and a lower limit of an uplink frequency are determined based on the first information if the first frequency band is not supported and the at least one second frequency band is supported by the terminal, and
- wherein the uplink frequency offset and the lower limit of the uplink frequency are used for identifying an uplink carrier frequency.

A base station supporting a plurality of frequency bands in a wireless communication system, the base station comprising:
- a transceiver;
- and
- a controller coupled with the transceiver and configured to:
- generate first system information including first information indicating a first frequency band supported by a cell and a list of at least one second information indicating at least one second frequency band supported by the cell,
- transmit the first system information to a terminal,
- generate second system information including uplink frequency information, first spectrum emission information corresponding to the first information and a list of at least one second spectrum emission information corresponding to the at least one second information, and
- transmit the second system information to the terminal,
- wherein an uplink frequency offset and a lower limit of an uplink frequency are determined based on the first information if the first frequency band is not supported and the at least one second frequency band is supported by the terminal, and
- wherein the uplink frequency offset and the lower limit of the uplink frequency are used for identifying an uplink carrier frequency.

A method for supporting multiple frequency bands by a terminal in a wireless communication system, the method comprising:
- receiving, from a base station, first system information including first information indicating a first frequency band supported by a cell and a list of at least one second information indicating at least one second frequency band supported by the cell;
- receiving, from the base station, second system information including uplink frequency information, first spectrum emission information corresponding to the first information and a list of at least one second spectrum emission information corresponding to the at least one second information;
- and
- applying a frequency band, indicated by first listed information supported by the terminal from the list of the at least one second information, to access the cell if the first frequency band is not supported by the terminal,
- wherein an uplink frequency offset and a lower limit of an uplink frequency are determined based on the first information if the first frequency band is not supported and the at least one second frequency band is supported by the terminal, and
- wherein the uplink frequency offset and the lower limit of the uplink frequency are used for identifying an uplink carrier frequency.
