Abstract:
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.
