Patent ID: 8391173

Claim:
A method for radio resource allocation in an Orthogonal Frequency Division Multiplexing communication system, wherein a frequency bandwidth is divided into a plurality of Physical Resource Units (PRUs), the method comprising: dividing PRUs into two groups, wherein a first group of the two groups is available for frequency selective allocations and a second group of the two groups is available for frequency diverse allocations; subdividing each of the two groups into multiple sets of PRUs; mapping the sets of PRUs from the first group of PRUs to consecutive PRUs allocated for contiguous segment allocation to produce contiguous segment PRUs (CS-PRUs); mapping the sets of PRUs from the second group of PRUs to consecutive PRUs allocated for distributed segment allocation to produce distributed segment PRUs (DS-PRUs); permuting the DS-PRUs to produce permuted DS-PRUs; and allocating the CS-PRUs and the permuted DS-PRUs to at least one frequency partition and wherein the CS-PRU and the permuted DS-PRU are concatenated.
