Patent ID: 7924794

Claim:
A method for centralized radio resource allocation in a communication network, comprising: providing a Network Control and Management System; providing a Base Station Cluster with a set of Base Station Entities, wherein permutation zones and radio resources are allocated to the Base Station Entities, a Permutation Zone is a number of contiguous Orthogonal Frequency-Division Multiple Access (OFDMA) symbols in a downlink or uplink that use the same permutation or mapping sequence between sub-channels and sub-carriers, the permutation zones are aligned when all the base station entities of all Base Station clusters are synchronized in time and frequency so that a starting time of each permutation zone is the same for all Base Station (BS) entities of all the base station clusters controlled by a Radio Resource Control (RRC) entity within the network control and management system; and controlling the allocation of permutation zones and radio resources to the Base Station Entities by aligning the permutation zones and radio resources of different Base Station Entities in the Base Station Cluster wherein aligning the permutation zones reduces Co-Channel Interference and mobile-to-mobile interference, by determining the radio resources to be used within each permutation zone by the Base Station Entities, wherein 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, wherein the Base Station Entities return towards the Network Control and Management System a second message including the information requested in the first message.
