A method is provided for allocation downlink bursts in a data region of a OFDMA data system, such data region having along one axis thereof increasing logical sub channel numbers and along another axis thereof increasing OFDMA symbol numbers, and wherein the burst are allocated into rectangular shaped sub regions within the data region. In one embodiment, the method allocates the bursts into rectangular shaped sub regions of the data region with minimum unused sub regions within the data region. In one embodiment, the method creates and locates the data region with minimum unused slots at the lowest logical sub channel number and the lowest OFDMA symbol number. In another embodiment, the method allocates the bursts within a data region having the largest number of OFDMA symbol numbers and then reduces the OFDMA symbol numbers of the data region only when the data region with the smaller OFDMA symbol numbers has less number of unused slots.
