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.

EU FP6 IST-4-027756 WINNER II, D6.13.14 WINNER II System Concept Description, Dec 2007
- 2007
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- This document contains a top-down view of the WINNER system with respect to logical node architecture, protocol architecture and cooperation architecture to give a basic understanding of the WINNER concept and as a complement to performance evaluations and design examples. The document also describes some of the important cross-layer optimizations that have been made. In addition to describing the concept, several example reference designs have been studied and are described.

- Data relating to residual deformations in human arteries are scarce. In this paper we investigate three-dimensional residual deformations for intact strips and for their separate layers from human aortas in their passive state. From 11 abdominal aortas with identified anamnesis, 16 pairs of rings and axial strips were harvested, and the rings cut open. After 16 h images of the resulting geometries were recorded, and the strips were separated into their three layers; after another 6 h images were again recorded. Image processing and analysis was then used to quantify residual stretches and curvatures. For each specimen histological analysis established that the intima, media and adventitia were clearly separated, and the separation was atraumatic. Axial in situ stretches were determined to be 1.196 +/- 0.084. On separation, the strips from the adventitia and media shortened (between 4.03 and 8.76% on average), while the intimal strips elongated on average by 3.84% (circumferential) and 4.28% (axial) relative to the associated intact strips. After separation, the adventitia from the ring sprang open by about 180 degrees on average, becoming flat, the intima opened only slightly, but the media sprang open by more than 180 degrees (as did the intact strip). The adventitia and intima from the axial strips remained flat, while the media (and the intact strip) bent away from the vessel axis. This study has shown that residual deformations are three dimensional and cannot be described by a single parameter such as 'the' opening angle. Their quantification and modeling therefore require consideration of both stretching and bending, which are highly layer-specific and axially dependent.

Tidskriftsartikel (refereegranskat)abstract
- WINNER is an ambitious research project aiming at identification, development, and assessment of key technologies for IMT-Advanced mobile communication systems. WINNER has devised an OFDMA-based system concept with excellent system-level performance for flexible deployments in a wide variety of operating conditions. The WINNER system provides a significant step forward from current 3G systems. Key innovations integrated into the system concept include flexible spectrum usage and relaying, adaptive advanced antenna schemes and pilot design, close to optimal link adaptation, hierarchical control signaling, and a highly flexible multiple access scheme. The end-to-end performance assessment results demonstrate that the WINNER concept meets the IMT-Advanced requirements.
