The Impact

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

Technical Challenges

Long Term Evolution-Advanced (LTE-Advanced) has been recently submitted by the 3rd Generation Partnership Project (3GPP) to the International Telecommunication Union (ITU) as one of the candidates 4G technologies. LTE-Advanced is expected to outperform its predecessor (i.e. LTE) by providing data rate up to 1Gbps and 500 Mbps in the downlink and uplink directions, respectively, also by supporting higher speed mobility (i.e. 500 km/h). In order to allow such advances in the performance, Radio Resource Management (RRM) must be effectively utilized. This paper studies the technical challenges associated with some of the RRM tasks (including Packet scheduling, interference management and handover control), in addition it presents from the open literature some of the proposed solutions to these technical challenges.

Radio Resources

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.

This paper provides a review of radio resource management technologies that can be used or proposed for OFDMA-based IMT-Advanced system.  IMT-Advanced specifications significantly enhanced the existing IMT 2000 standard which are represented by LTE-Advanced and mobile WiMAX as the main successful candidates. One of the key components for OFDMA is Radio Resource Management (RRM) which is used to manage radio resources for the air interface in a cellular network. The main purpose of RRM is to utilize the available radio resources efficiently. The RRM tools such as power control, handover, packet scheduling, resource allocation and, load and admission control are needed to be controlled to maximize the performance efficiency in the wireless networks. By controlling these RRM tools, we are able to maximize the number of users in the network and let the users experience the best Quality of Service (QoS) and throughput.
