Abstract: A method and a system for transmitting and receiving signals using multiple frequency bands in a wireless communication system are provided to transmit and receive mass data by assisting an MS(Mobile Station) to use a plurality of FAs(Frequency Assignments) in a wireless communication system. An MS acquires synchronization with a BS(Base Station) through a specific FA(201). The BS and the MS execute initial ranging through the exchange of ranging messages(203). The MS transmits an SBC-REQ(Subscriber Basic Capability Request) message to the BS(205). In this case, the SBC-REQ message contains information about whether the MS supports overlay mode and information about the maximum number of usable FAs when the MS supports overlay mode. In response to the SBC-REQ request, the BS transmits an SBC-RSP(SBC Response) message to the MS(207). In this case, the SBC-RSP message contains information about whether the BS supports overlay mode and information about the number of FAs to be provided when the BS supports overlay mode. Afterwards, the BS executes authentication and registration procedures with the MS(209,211).
