— This paper proposes a low-complexity model for vertical antenna radiation patterns, e.g. for inclusion in system-level simulations. They can be seen as extensions to the horizontal radiation pattern model used in 3GPP simulation scenarios. The model is verified against and compared to predicted and measured data from real networks. The impact on(More)
—The HSPA Evolution will during the next decade be a key radio access technology for a cost-effective provisioning of mobile broadband services. In addition to the continuous improvements of WCDMA/HSPA in terms of spectral efficiency and latency, " multi-carrier operation " (or " carrier aggregation ") for individual connections is now introduced. This(More)
— For voice, an efficient radio resource management (RRM) essentially boils down to providing a predefined signal to interference ratio (SIR) at lowest cost possible and centralized schemes has, evidently, been an effective approach to address these problems. Delay-elastic data services, however, introduce both heterogeneous user requirements and(More)
— Radio resource management (RRM) across operator boundaries is emerging as a salient feature for wireless systems beyond 3G. Until recently, research has been confined to solutions where cooperating networks enter explicit sharing agreements that define how responsibilities and revenues should be divided. An alternative would be to share the infrastructure(More)
— In radio resource management for cellular networks a trade-off has to be made between the congestion level, related to cell coverage and intercell interference, and the Quality of Service (QoS), or data rates of the users. Herein this is implemented by using a fast inner power control loop and an outer rate control algorithm, working on a slower time(More)
