Interference management for mixed services through power control and service-based power setting

The efficient handling of radio resources is a crucial topic for the success of cellular systems. Since interference is the main capacity limiting factor, radio resource management techniques able to reduce/control interference can be of great utility to improve system capacity and QoS. We evaluate power control and service-based power setting (SBPS) as means to improve the capacity of single and multi-service cellular networks. A complete system level simulator is used to assess the performance gains of these two techniques, considering a voice service, using the EFR and MR59-FR voice codecs, and a WWW data service in a GSM/EDGE network. The capacity gains of applying power control to these services is characterized for single service scenarios. Mixed-service simulations are performed for different mixes of EFR and WWW users and mixes of EFR and MR59-FR users in order to assess the performance of SBPS, either alone or combined with power control. Finally, conclusions are drawn on the results presented for the evaluated scenarios.
