Context-aware Radio Resource Management in HetNets
2014 IEEE Wireless Communications and Networking Conference Workshops (WCNCW), 2014In order to address the rapid increase in data-rate requirements in existing and upcoming wireless communication systems, one solution is to add more base-stations to achieve increased spectrum reuse. A Heterogeneous Network (HetNet)—consisting of a deployment of a variety of different types of small cells in a cellular infrastructure—is one ...

Radio resource management-an overview
Proceedings of Vehicular Technology Conference - VTC, 2002Comparing market estimates for wireless personal communication and considering proposals for wideband multimedia services with the existing spectrum allocations for these types of systems show that spectrum resource management remains an important topic in the near and distant future.

Elastic Game Based Radio Resource Management
2012 IEEE 75th Vehicular Technology Conference (VTC Spring), 2012With the abundance of diverse air interfaces in the same operating area, a mobile user is able to connect concurrently to different wireless access networks in order to meet more easily its target performance. In this paper, we consider the downlink of a multi-class hybrid network with two Radio Access Technologies (RAT): WiMAX and WiFi.

An Efficient Radio Resource Management Scheme for Cognitive Radio Networks
2010Cognitive radio network is proposed to better spectrum utilization. In this network, secondary users (SUs) can use the spectrum band reserved for primary users (PUs) without generated interference. And SU has to vacate the channel when PU arrives. In order to improve the system performance and guarantee the QoS requirements, we propose an efficient ...

Radio Resource Management for Fast Fading Environments
Journal of Communications, 2011Adaptive resource allocation based on perfect Channel State Information (CSI) can significantly improve the performance of Orthogonal Frequency Division Multiple Access (OFDMA) systems. However, in real systems, accurate CSI is impossible because of noisy channel estimates, channel feedback delays, and processing delays.

Radio resource management in cellular multihop networks
European Transactions on Telecommunications, 2004AbstractIn future mobile broadband radio systems, multihop for coverage extension is seen as a basic building block. Here, we investigate radio resource management (RRM) for multihop networks and assume that the central access point (AP) can control the whole multihop network based on channel state information (CSI) of all links.

Vertical handoffs as a radio resource management tool
Computer Communications, 2008Vertical handoffs occur when a user changes association from one type of wireless access technology to another while maintaining an active session. Much work has been done in ensuring seamless handoffs that also preserve quality of service (QoS). However, network operators can exploit vertical handoffs through dedicated radio resource management (RRM ...
