CELTIC CP5-026 WINNER+, D1.5 Intermediate Report on System Aspect of Advanced RRM
- 2009
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- The deliverable describes the second set of best innovations proposed in the framework of the WP1 on system aspect of advanced Radio Resource Management (RRM) approved by the System Group. These concepts consist of promising innovative techniques and include an initial evaluation of the performance and benefits as far as already available. A brief description of each technique together with the relevant state of the art is provided.Moreover, first considerations about the requirements on the system, especially regarding measurements, signalling, architecture and protocols are described. The last set of innovations will be ready for the final deliverable of proof of concept evaluation.

Konferensbidrag (refereegranskat)abstract
- This paper introduces a framework of mobility management and call-handling based on policy enhancement towards the IMT-Advanced systems. The function allocation and several selected mechanisms for the framework are described. The framework is based on the EU IST WINNER research project results and enables scalable service provisioning by setting the end user satisfaction and overall system performance as general goals. This paper aims to serve as a reference for the design of IMT-Advanced systems.

Requirements and Algorithms for Cooperation of Heterogeneous Radio Access Networks
- 2008
-
Ingår i: Wireless Personal Communications. - : Springer.
-
Tidskriftsartikel (refereegranskat)abstract
- This paper defines the requirements for cooperation of heterogeneous radio access networks (RANs) and proposes a novel radio resource management (RRM) framework for support of mobility and quality of service (QoS) in a heterogeneous communication environment comprising IMT-Advanced and legacy systems. The reference IMT-Advanced system is the one developed within the IST project WINNER (IST-2003-507581 Project Wireless Initiative New Radio, http://www.ist-winner.org). The RRM mechanisms are evolved from traditional ones to comply with the requirements imposed by a simplified new (RAN) architecture as proposed for IMT-Advanced systems. The RRM mechanisms are evaluated for the scenario of intra-RAN and inter-RAN user mobility. The RRM framework incorporates as novelty improved triggering mechanisms, a network-controlled mobility management scheme with policy enforcement on different levels in the RAN architecture, and a distributed handover and admission control mechanism for fast decision polling at different levels of the RAN. The RRM framework is further enhanced with computational intelligence based on fuzzy logic algorithms to enhance the process of handover. The RRM framework has been evaluated in terms of reduced user blocking probabilities

- 2010
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- This deliverable summarizes the most promising enabling techniques for LTE-A and beyond in seven major areas. These areas are: Carrier Aggregation, Coordinated Multipoint Systems, Femtocells, Network Coding, MIMO, Quality of Service, Resource allocation, and Relaying. A description of the most relevant scenarios where the techniques can be used is given. Further the end-2-end performance approach is presented. Finally future research directions of enabling techniques beyond LTE-A are given.

The Road to IMT-Advanced Communication Systems: State-of-the-Art and Innovation Areas Addressed by the WINNER+ Project
- 2009
-
Ingår i: IEEE Communications Magazine. - 0163-6804 .- 1558-1896. ; 47:6, s. 38-47
-
Tidskriftsartikel (refereegranskat)abstract
- The WINNER project phases I and II contributed to the development, integration and assessment of new mobile networks techniques from 2004 to 2007. Some of these techniques are now in the 3GPP LTE and IEEE 802.16 (WiMAX) standards, while others are under consideration for LTE-Advanced and 802.16m. The WINNER+ project continues this forward-looking work for IMT-Advanced technologies and their evolutions, with a particular focus on 3GPP LTE-Advanced. This article provides an overview of the WINNER system concept and several of its key innovative components.

CELTIC CP5-026 WINNER+, D1.9 Final Innovation Report
- 2010
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- This deliverable is the final innovation report from the innovation workpackage in WINNER+. The document describes the latest innovations and their assessment as well as summarizes the innovations developed in the work package during the project. We analyze the suitability of these innovations as technology enablers for improving current systems, in particular IMT Advanced and beyond.
