Abstract

W-CDMA performance is tightly coupled to the amount of interference in the air interface and eventually depends on many strongly interrelated system parameters that need to be suitably managed through radio resource management (RRM) strategies in order to achieve a high efficiency. Interference characterisation in terms of average and standard deviation, which are suitable for radio network planning, may not suffice for a proper RRM design because of its inherently dynamic nature. The time correlation of the interference and the main system level parameters affecting its dynamics are raised: shadow fading, mobile speed, traffic characteristics and cell load.
