Abstract
A method for staggered zone resource allocation in an orthogonal frequency division multiple access (OFDMA) system having a cluster includes: dividing a frequency resource of the OFDMA system into a plurality of time zones along a time axis; determining at least two resource allocation start zones among the plurality of time zones in at least two cells of the cluster, respectively; arranging users in each of the at least two cell according to a path loss in a descending order; and sequentially allocating the frequency resource to the arranged users from the at least two resource allocation start zones in the at least two cells, respectively.
