Method and apparatus for supporting multiple frequency assignment in wireless communication system

An operating method of a Base Station (BS) for supporting multicarrier transmission in a wireless communication system, the method comprising:

• performing a multicarrier capability negotiation with a Mobile Station (MS) during a network entry procedure;
• broadcasting, periodically, configuration information on all carriers supported by the BS;
• after the network entry procedure is completed, receiving a first control message including information on a subset of carriers, which are simultaneously processable by the MS, determined from among the carriers supported by the BS, from the MS;
• assigning carriers, based on the subset of carriers determined by the MS, for a multicarrier operation;
• and
• transmitting a second control message including information of carriers assigned to the MS,
• wherein the second control message comprises a number of the carriers assigned by the BS to the MS and indexes of the carriers assigned by the BS to the MS.

An apparatus of a mobile station for supporting multicarrier transmission in a wireless communication system, the apparatus comprising:

• a controller for performing a multicarrier capability negotiation with a Base Station (BS) during a network entry procedure;
• a receiver for, after the network entry procedure is completed, receiving configuration information on carriers supported by the BS, which is periodically broadcasted by the BS;
• and
• a transmitter for transmitting a first control message including information on carriers supported by the MS, to the BS;
• wherein the controller, before the transmitting the first control message, determines a subset of carriers that are simultaneously processable by the MS, from among the carriers supported by the BS, based on the configuration information,
• wherein the receiver receives a second control message including information of carriers assigned, based on the information on the carriers supported by the MS, for the multicarrier operation from the BS, and
• wherein the second control message comprises a number of the carriers assigned by the BS to the MS and indexes of the carriers assigned by the BS to the MS.
