Provided are a wireless data communication apparatus and a method using a multicarrier, and a transmission frame format therefore, wherein through the wireless data communication method, a plurality of stations can transmit and receive burst data to and from a net access group switching center wirelessly using a multicarrier. The method includes: (a) allocating a sub-carrier channel set to one of the plurality of stations that requests allocation of the sub-carrier channel set consisting of sub-carriers of a 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 a second predetermined number to the detected station.
A wireless data communication method by which a plurality of stations can transmit and receive burst data to and from a net access group switching center wirelessly using a multicarrier, the method comprising:
A wireless data communication apparatus through which burst data is received and transmitted wirelessly using a multicarrier, comprising:
A station that transmits and receives burst data to and from a net access group switching center wirelessly using a multicarrier, wherein the station transmits information requesting the allocation of a sub-carrier channel set, which consists of sub-carrier of a first predetermined number out of a plurality of sub-carriers that exist at a predetermined time, to the net access group switching center, and activates the sub-carrier channel set allocated by the net access group switching center so as to transmit data, by varying at least one sub-carrier in the allocated sub-carrier channel.
A net access group switching center that transmits and receives burst data to and from a plurality of stations wirelessly using a multicarrier, wherein the net access group switching center allocates a sub-carrier channel set to each of the plurality of stations that requests allocation of the sub-carrier channel set consisting of sub-carriers of a first predetermined number out of a plurality of sub-carriers at a predetermined point of time, checks for activation of at least one of the sub-carrier channel sets by determining if at least one sub-carrier in the allocated sub-carrier channel set is varied, and allocates resources of a second predetermined number to the stations having an activated sub-carrier channel set allocated thereto, based on the checked results.
