Abstract
A method and an apparatus are configured to support a plurality of Media Access Control (MAC) versions in a broadband wireless communication system. An operating method of a terminal to support the multiple MAC versions in the broadband wireless communication system includes receiving a message comprising information of one or more MAC versions supported by a base station, from the base station; and sending information of one or more MAC versions supported by the terminal, to the base station using a message. Thus, in the wireless environment where the multiple MAC versions are mixed, the MAC version can be matched.

An operating method of a terminal to support a plurality of Media Access Control (MAC) versions in a broadband wireless communication system, the method comprising:
- receiving a message comprising information of one or more MAC versions supported by a base station, from the base station;
- and
- sending information of one or more MAC versions supported by the terminal, to the base station using a message.
An operating method of a terminal to support a plurality of Media Access Control (MAC) versions in a broadband wireless communication system, the method comprising:
- receiving a broadcast message which comprises first MAC version information of a highest version supported by a base station;
- determining whether the terminal comprises one or more supportable MAC versions equal to or lower than the first MAC version;
- transmitting a second MAC version value of the highest version among the one or more supportable MAC versions equal to or lower than the first MAC version, and information of one or more supportable MAC versions equal to or lower than the second MAC version using a ranging request message;
- and
- receiving a third MAC version value to use, from the base station using a ranging response message.
An operating method of a base station to support a plurality of Media Access Control (MAC) versions in a broadband wireless communication system, the method comprising:
- transmitting a broadcast message which comprises information of one or more first MAC versions supported by the base station, to a corresponding terminal;
- receiving a message which comprises information of one or more second MAC versions supported by the corresponding terminal, from the corresponding terminal;
- and
- selecting a MAC version to be used by comparing the first MAC version information and the second MAC version information.
An operating method of a base station to support a plurality of Media Access Control (MAC) versions in a broadband wireless communication system, the method comprising:
- broadcasting a first MAC version value which is a highest version of MAC versions supported by the base station, to a corresponding terminal;
- after sending the broadcast message, receiving a ranging request message which comprises a second MAC version value, which is the highest version supported by the corresponding terminal, and information of one or more supportable MAC versions lower than the second MAC version;
- and
- determining a MAC version to be used using MAC version information supported by the base station and MAC version information supported by the corresponding terminal, and transmitting the determined MAC version value using a ranging response message,
- wherein the first MAC version is higher than or equal to the second MAC version.
An apparatus of a terminal to support a plurality of Media Access Control (MAC) versions in a broadband wireless communication system, the apparatus comprising:
- a receiver for receiving a broadcast message comprising information of one or more MAC versions supported by a base station, from the base station;
- and
- a ranging controller for sending information of one or more MAC versions supported by the terminal, to the base station using a message.
An apparatus of a terminal to support a plurality of Media Access Control (MAC) versions in a broadband wireless communication system, the apparatus comprising:
- a receiver for receiving a broadcast message which comprises first MAC version information of a highest version supported by a base station;
- a MAC version checker for determining whether there are one or more supportable MAC versions equal to or lower than the first MAC version;
- and
- a ranging controller for transmitting a second MAC version value of the highest version among the one or more supportable MAC versions equal to or lower than the first MAC version, and information of one or more supportable MAC versions equal to or lower than the second MAC version using a ranging request message, and receiving a third MAC version value to use, from the base station using a ranging response message.
An apparatus of a base station to support a plurality of Media Access Control (MAC) versions in a broadband wireless communication system, the apparatus comprising:
- a transmitter for transmitting a broadcast message which comprises information of one or more first MAC versions supported by the base station, to a corresponding terminal;
- and
- a controller for receiving a message which comprises information of one or more second MAC versions supported by the corresponding terminal, from the corresponding terminal, and selecting a MAC version to be used by comparing the first MAC version information and the second MAC version information.
An apparatus of a base station to support a plurality of Media Access Control (MAC) versions in a broadband wireless communication system, the apparatus comprising:
- a transmitter for transmitting broadcast message comprising a first MAC version value which is a highest version supportable;
- and
- a ranging controller for receiving a ranging request message which comprises a second MAC version value, which is the highest version supported by a corresponding terminal, and information of one or more supportable MAC versions lower than the second MAC version, determining a MAC version to use using MAC version information supported by the base station and MAC version information supported by the corresponding terminal, and transmitting the determined MAC version value using a ranging response message,
- wherein the first MAC version is higher than or equal to the second MAC version.
