This chapter gives an overview of the background and functionality of the high speed downlink packet access (HSDPA), and provides insights into the radio resource management of integrated UMTS/HSDPA networks. The high speed downlink packet access (HSDPA) is part of the evolution of the universal mobile telecommunication system (UMTS). It is often referred to as 3.5G system, in contrast to UMTS, which is a third generation system. The authors introduce aspects of radio resource management specific to the HSDPA like channel-aware scheduling and radio resource sharing strategies. Furthermore, the impact of radio resource management on the quality of service is analyzed and it is shown that the selection of an RRM strategy is an integral part of the network planning and deployment process

The IEEE 802.16 has defined wireless access systems called WiMAX. These systems provide high-speed communications over long distances. To support multimedia applications, some service classes with Quality of Service (QoS) requirements are defined in IEEE 802.16, but the QoS scheduler is not standardized. The scheduling mechanism has a significant effect on the performance of WiMAX systems for use of bandwidth and radio resources. Some scheduling algorithms have been introduced by researchers. This study focuses on scheduling techniques proposed for WiMAX. The authors analyze a number of WiMAX scheduling algorithms in the Point-to-Multi-Point (PMP) mode and highlight their main points.
