Disclosed is a cellular-based wireless communication system, and more particularly a method for allocating resources for data transmission in a cellular-based wireless communication system employing a multicarrier scheme. Frequency resources are divided into time slots defined by one frame and the divided time slots are allocated to an uplink and the downlink. During a predetermined time period, the frequency resources are allocated as resources for transmitting sync preambles. During a next predetermined time period, the frequency resources are allocated in such a manner that the frequency resources for sectors are successively and repeatedly used as resources for transmitting broadcasting messages on a sector-by-sector basis. In the remaining time slots, except the time slots for transmitting the preambles and the broadcasting messages, the frequency resources are allocated as resources for transmitting channel estimation midambles for dynamic channel allocation.
