Cell sectorization is commonly used to increase system capacity in cellular systems and is easily implemented. We propose a technique to improve system capacity based on adaptive sectorization. Sectors are rotated and/or resized adaptively in order to equalize the uplink C/I or the total downlink transmitted power in each sector The performance of the proposed procedure is analyzed for both uplink and downlink transmissions. Noticeable performance improvements are obtained when traffic is not uniformly distributed both spatially and in terms of data rate
