The purpose of this thesis is to address a variety of performance related aspects in terms of Third Generation (3G) mobile networks. From a practical perspective, wireless network sets a very demanding environment for different services due to, e.g., limited User Equipment (UE) battery power, transmission delays, packet loss and varying network performance. This thesis addresses the aforementioned challenges by evaluating different transmit diversity options, battery saving opportunities, Interference Coordination (IC), Range Extension (RE) and Dual-Carrier (DC) in Uplink (UL). The studies are conducted with the help of time driven quasi-static system level simulator where, e.g., fading, propagation and Radio Resource Management (RRM) functionality is explicitly taken into account.
