Allocating resources in a frequency-time space to mobile station data

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

• assigning, by a processor, two-dimensional rectangular regions in a frequency-time space to data bursts associated with mobile stations;
• determining, by the processor, that at least one data burst does not fit in an available space in the frequency-time space;
• in response to the determining, the processor reshaping the assigned two-dimensional rectangular regions;
• and
• applying, by the processor, a fitting algorithm to further define the two-dimensional rectangular regions, where the fitting algorithm assigns differently shaped two-dimensional regions to fast-moving mobile stations and to slow-moving mobile stations, the fast-moving mobile stations moving at a speed greater than the slow-moving mobile stations, wherein the fitting algorithm increases a ratio of a width of the rectangular region to a height of the rectangular region for a mobile station that is fast moving, and increases a ratio of a height of the rectangular region to a width of the rectangular region for a mobile station that is slow moving.

A base station comprising:

• a wireless transceiver, configured to communicate with mobile stations;
• wherein the base station is configured to implement a scheduler, wherein the schedule is configured to:
• assign data bursts associated with mobile stations communicated with the base station to two-dimensional rectangular regions in a frequency-time space;
• determine that at least one data burst does not fit in an available space in the frequency-time space;
• in response to the determining, reshaping the assigned two-dimensional rectangular regions;
• and
• apply a fitting algorithm to further define the two-dimensional rectangular regions, where the fitting algorithm assigns differently shaped two-dimensional regions to fast-moving mobile stations and to slow-moving mobile stations, the fast-moving mobile stations moving at a speed greater than the slow-moving mobile stations, wherein the fitting algorithm increases a ratio of a width of the rectangular region to a height of the rectangular region for a mobile station that is fast moving, and increases a ratio of a height of the rectangular region to a width of the rectangular region for a mobile station that is slow moving.

An article comprising at least one non-transitory computer-readable storage medium containing instructions that when executed cause a system to:

• assign, 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;
• divide a number of slots in the two-dimensional rectangular region allocated to each mobile station by prime factors;
• provide the prime factors to a fitting algorithm;
• use, by the fitting algorithm, the prime factors to further shape the two-dimensional rectangular regions;
• determine that at least one data burst does not fit in an available space in the frequency-time space;
• and
• in response to the determining, reshape 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.
