CELTIC CP5-026 WINNER+, D1.4 Initial Report on Advanced Multiple Antenna Systems
- 2008
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- This deliverable captures the first set of best innovative concepts identified in the field of Advanced Multiple Antenna Systems for potential inclusion into the WINNER+ system concept. The concepts consist of promising principles or ideas as well as detailed innovative techniques. For each concept, the associated benefits as well as the corresponding requirements on the system architecture and protocols, measurements and signalling, are considered. The document involves two main tracks: development of new advanced antenna schemes in the context of conventional cellular networks, and a study of coordinated multipoint transmission and reception, where multiple network nodes cooperate to enhance system performance.

CELTIC CP5-026 WINNER+, D1.8 Intermediate Report on CoMP (Coordinated Multi-Point) and Relaying in the Framework of CoMP.
- 2009
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- This deliverable is an intermediate report on CoMP (Coordinated Multi-Point) and on Relaying in the Framework of CoMP. It describes the second set of innovations encompassing concepts about promising principles or ideas as well as detailed innovative techniques in the framework of WINNER+ system concept. For each concept, the associated benefits as well as the corresponding requirements on the system architecture and protocols, measurements and signalling, are considered. Regarding CoMP algorithms, focus is put on schemes with reduced requirements in terms of backhauling considering two categories: “Coordinated Beamforming”, and “Joint Processing”. As for relaying, a relay-assisted interference channel, and a distributed LDPC coding for a Decode and Forward relay are introduced.

Coordinated MultiPoint Systems for IMT-Advanced in the Framework of Winner+ Project
- 2009
-
Ingår i: Proc. ICT Mobile Summit 2009, Santander, Spain, June 2009.
-
Konferensbidrag (refereegranskat)abstract
- The growing demand for improved performance in cellular radio networks led to the investigation of novel techniques able to cope for these needs. One of the most promising, currently evaluated in the framework of standardization bodies following ITU-R process for IMT-Advanced, is the so-called Coordinated MultiPoint (CoMP) access network architecture and related approaches and algorithms. CoMP is one of the most extensively studied topics in the context of Winner+ CELTIC European project. CoMP brings forward the concept of Advanced Antenna systems, introducing a degree of collaboration among a multiplicity of nodes exchanging information among them. Consequently, CoMP aims to exploit concurrently signals coming from all the nodes, transforming inter-cell interfering signals in useful ones, especially for cell-border users. In this paper some possible CoMP architectures are listed and the first results of simulations on CoMP systems, starting from ideal assumptions, are reported.

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.

EU FP7 INFSO-ICT-317669 METIS, D1.1 Scenarios, requirements and KPIs for 5G mobile and wireless system
- 2013
-
Bok (övrigt vetenskapligt/konstnärligt)abstract
- This deliverable introduces generic scenarios based on fundamental challenges, and the specific problem description of test cases that will be relevant for beyond future radio access. Specific characteristics of each scenario and each test case include the key assumptions regarding requirements and key performance indicators. In order not to constrain the potential solutions, the requirements are specified from an end-user perspective. The deliverable will not only serve as the guideline for the technical work and system concept design in METIS, but also can serve in external research communities to help to harmonize the work towards the future radio access system including the new generation system of 5G

Scheduling-Assisted Joint Processing for CoMP in the Framework of the WINNER+ Project
- 2010
-
Ingår i: Proc. Future Network & MobileSummit 2010, June 2010, Florence, Italy..
-
Konferensbidrag (refereegranskat)abstract
- The goal of this paper is to present the main achievements reached within the WINNER+ project concerning, in particular, clustering as a way to improve thefeasibility of joint processing schemes as enablers of coordinated multipoint solutions. Three different approaches are presented. First, a single and static cluster of base stations is considered. In this case, a user-centric partial joint processing scheme isproposed to reduce with respect to a fully centralized approach both the inter-base information exchange and feedback from the users. Second, a dynamic and network centric clustering approach is presented. It is shown that substantial gains can be obtained with respect to a static clustering scenario when a central unit jointly createsthe clusters of collaborating base stations, schedules the users in these clusters and calculates the beamforming coefficients and the power allocation. Finally, a dynamicclustering technique is combined with multi-antenna receivers. In addition, a concept for a scalable channel state information feedback is also presented.
