<p>Provided are a wireless data communication apparatus and a method using a multicarrier, and a transmission frame format therefor. Through wireless data communication method, stations can transmit and receive burst data to and from a net access group switching center in wireless using a multicarrier. The method includes the steps of: (a) allocating a sub-carrier channel set to one of the stations that requests allocation of the sub-carrier channel set consisting of sub-carriers of first predetermined number out of a plurality of sub-carriers at a predetermined point of time; (b) activating the sub-carrier channel set allocated to the station which desires to transmit the data; and (c) checking the activation of the sub-carrier channel set, detecting a station that requests the allocation of resources based on the checked results, and allocating resources of second predetermined numbers to the detected station. Therefore, it is possible to prevent contention of a plurality of stations for request of data transmission to the net access group switching center, thereby enabling a stable request for resources. Further, the efficiency of the use of resources can be maximized. <IMAGE></p> |
