A resource allocation method and system in a communication system are provided to provide a communication service to a user stably and improve a usage efficiency of resources. A BS(Base Station) receives search information including information about a frequency band that can be used by an MS of a sub-system from the MS(301). The BS allocates the available frequency band, namely, resources, to the MS(303) and receives CSI(Channel State Information), namely, energy measurement information of each frequency band, from the MS(305). The BS checks whether a main system wants to use the frequency band allocated to the MS(307). If the main system wants to use the frequency band, the BS checks whether a certain portion of the frequency band can be used(311). If the certain portion of the frequency band can be used, the BS allocates the certain portion of the frequency band to the MS(313). |
