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

  • a wireless device assigning two-dimensional rectangular regions in a frequency-time space to data bursts associated with mobile stations using at least one predefined shaping rule;

    the wireless device determining 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 wireless device reshaping the assigned two-dimensional rectangular regions, wherein reshaping the assigned two-dimensional rectangular region comprises modifying the at least one predefined shaping rule to adjust a shape of at least one rectangular region specified by the at least one predefined shaping rule, wherein modifying the at least one predefined shaping rule comprises relaxing the at least one predefined shaping rule to allow more data bursts to be allocated to regions in the frequency-time space.
