    • A method for terminal accessing system with great bandwidth and the frame structure thereof are provided, wherein the method comprises: (a) dividing the system bandwidth into a plurality of operating frequency bands, for each of the operating frequency bands, setting synchronization channels, broadcast channels and random access channels respectively, and in the range of the one unit of the bandwidth centered at the center frequency point of the system, setting at least one group of synchronization channels, broadcast channels, random access channels, and operating frequency band allocation channels, (b) the terminal searching the network, interacting with the network side via the synchronization channel, the broadcasting channel and the random access channel, and completing the downlink synchronization, the cell searching and the registration procedure with the network side; (c) the network side informing the terminal of the operating frequency band allocated for the terminal through the operating frequency band allocation channel, upon having receipt, the terminal operating on the allocated operating frequency band. With the method of the present invention, during the initial access procedure, the resource occupied by the terminal could be as few as possible, and the effect ofthe initial access on the operating frequency band could be minimized.
