Patent ID: 7894394

Claim:
A radio resource allocation method of a Base Station (BS) in a multi-channel system where a diversity channel and a band Adaptive Modulation and Coding (AMC) channel coexist, the method comprising the steps of: determining, by the BS, a type of a channel to be allocated to terminals that request a resource allocation; allocating resources to at least one terminal as resources of the band AMC channel within a frequency band preferred by the at least one terminal, when the band AMC channel is assigned to the at least one terminal; generating a virtual resource space comprising resources that are not allocated as the resources of the band AMC channel; and allocating resources of the virtual resource space to one or more terminals assigned the diversity channel; wherein the virtual resource space is a collection of resources not allocated to the at least one terminal as the resources of the band AMC channel in a same time domain as a time domain that allocates the resources of the band AMC channel.
