Abstract: A method for allocating an operating channel priority between frequency sharing systems includes: a coarse channel priority allocating operation of collecting information about a target white space object (WSO) for priority allocation of an operating channel and information about the operating channel, and classifying the operating channel based on a predetermined criterion; and a fine channel priority allocating operation of removing the operating channel by checking its interference level. The information about the target WSO preferably includes channel classification information and coexistence set information such as the license type of the set and network technology information. The operating channel information may include a total occupancy rate and the number of elements in a coexistence set. The coarse channel priority allocating operation may remove operating channels used by a coexistence set element of a license type. The operating channels may be allocated to a first group used by a coexistence set element of the same network technology as the target WSO; or a second group, comprising channels excluded from the first group. Priority of the channels in the groups is allocated in ascending order of a total occupancy rate. Apparatus for implementing the method is also disclosed.
