1. A method of allocating resources in an orthogonal frequency domain multiple access (OFDMA) system, comprising:

  • assigning, by a processor using an algorithm having at least one predefined shaping rule, two-dimensional rectangular regions in a frequency-time space to data bursts associated with mobile stations;

    dividing a number of slots in the two-dimensional rectangular region allocated to each mobile station by prime factors;

    providing the prime factors to a fitting algorithm;

    using, by the fitting algorithm, the prime factors to further shape the two-dimensional rectangular regions;

    determining, by the processor, that at least one data burst does not fit in an available space in the frequency-time space; and

    in response to the determining, the processor reshaping the assigned two-dimensional rectangular regions, wherein reshaping the assigned two-dimensional rectangular regions comprises modifying a shape of at least a particular one of the assigned two-dimensional rectangular regions based on changing the at least one predefined shaping rule.
