Patent ID: 7912470

Claim:
A method of partitioning resources in a Cognitive Radio (CR) wireless communication system, the method comprising: determining if at least two new Base Stations (BSs) are newly installed in a service area of a prior Base Station (BS); allocating a contention-based ranging subchannel of the prior BS to the at least two BSs when the at least two BSs are in the absence of any available frequency band; performing contention-based ranging between the at least two new BSs through the contention-based ranging subchannel; allocating uplink resources of the prior BS to a new BS being one of the at least two new BSs as a result of the contention-based ranging; requesting resource partitioning to the prior BS through the uplink resources by the new BS; and receiving information about partitioned resources in response to the requesting from the prior BS by the new BS, wherein the contention-based ranging subchannel is periodically allocated for contention between only the at least two new BSs.
