发明名称 Method of semidynamic centralized interference coordination for cellular systems
摘要 A method for operating a radio access network (RAN), wherein the RAN comprises a plurality of base stations (BS) and a base station controller (BSC), wherein the BSC allocates radio resources (space, time, frequency, energy) of a resource domain, and wherein each base station (BS) may handle within a corresponding base station area (BSA) a plurality of subscriber stations (SS), is characterized in that each BSA is statically divided into a plurality of spatial subsectors (BEA), that a subset of the time-frequency domain of the resource domain is allocated to each of the subsectors, that the BSs collect traffic information for each subsector belonging to their respective BSA, the traffic information comprising interference conflict scenarios and traffic load, that the BSs summarize the traffic information for each subsector belonging to their respective BSA, that the BSs provide the BSC with said summarized traffic information for each subsector belonging to their respective BSA regularly, in particular periodically, that the BSC analyses the summarized traffic information for each subsector and re-allocates subsets of the time-frequency domain to the subsectors regularly, in particular periodically, in order to minimize interference between BSs, and that each BS comprises an independent local scheduling entity (ILSE) allocating radio resources of a subset of the radio resource domain, allocated to a given subsector at a given instant in time, to SSs within this subsector. The method allows a large throughput for each base station at a low management effort within the RAN.
