FRACTIONAL FREQUENCY REUSE IN OFDMA

摘要

For enhancing user throughput and coverage within a multi-cell radio system a method for operating a multi-cell radio system, especially an OFDMA-based radio system, is claimed, the system comprising a plurality of base stations, wherein different frequency reuse factors are used within different reuse zones of one cell by means of a fractional frequency reuse (FFR) scheme, the method is comprising the following steps: allocating a size or resource to the different reuse zones, and allocating users into different reuse zones. Further, an according multi-cell radio system is claimed, preferably for carrying out the above mentioned method.
