A method for centralized radio resource allocation in a communication network including a Network Control and Management System and at least one Base Station Cluster having a set of Base Station Entities to which respective permutation zones and radio resources are to be allocated. The Network Control and Management System controls the allocation of permutation zones and radio resources to the Base Station Entities by aligning the permutation zones of different Base Station Entities and by determining the radio resources to be used within each permutation zone. Preferably, the Network Control and Management System issues towards the Base Station Entities a first message requesting information on the radio resources available including specific information items for each permutation zone. The Base Station Entities return towards the Network Control and Management System a second message including the information requested in said first message, and the Network Control and Management System issues towards the Base Station Entities a third message including commands to align the permutation zones of different Base Station Entities to determine the radio resources to be used within each permutation zone.
