Apparatus and method for supporting different frame structures in broadband wireless communication system

A communication method of a Base Station (BS) in a broadband wireless communication system supporting different frame structures, the method comprising the steps of:

• determining a frame structure to be provided;
• generating a MAP message comprising an indicator that indicates a new standard if the provided frame structure conforms to the new standard;
• and
• transmitting the generated MAP message by performing physical layer encoding thereon.

A communication method of a Mobile Station (MS) in a broadband wireless communication system supporting different frame structures, the method comprising the steps of:

• obtaining frame synchronization by using a preamble signal;
• decoding at least one MAP message received in at least one frequency band, after obtaining the frame synchronization;
• determining whether the MAP message conforms to a new standard by checking a MAP indicator included in the MAP message;
• and
• analyzing the remaining fields included in the MAP according to the new standard, when the MAP message conforms to the new standard.
