Abstract	To provision the enhanced support for wireless Internet services, high speed downlink packet access (HSDPA) was standardized in 3GPP. It offers peak air interface data rates of up to 14.4 Mbps with 5 Mhz bandwidth, thus dramatically improving the existing packet service capability of UMTS R99. At the same time, Evolution-Data Optimized (EV-DO) has been standardized in 3GPP2 to provide up to 4.9 Mbps throughput with 1.25 Mhz bandwidth. However, because of inter-cell interferences, users in the cell edge area generally cannot enjoy the higher data rate supported by the standard. Moreover, to meet the system fairness criterion, a base station usually needs to allocate un-proportional radio resource to these users. In this paper, we propose a simple interference mitigation scheme to enhance cell edge user data rate through network coordination. It is demonstrated through extensive simulations that the scheme significantly improves cell edge user throughput without lowering the total system capacity and spectral efficiency.
