EU FP6 IST-2003-507581 WINNER, D3.1 Description of identified new relay based radio network deployment, Oct 2004
- 2004
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- In D3.1 the first concept for a WINNER radio network deployment mainly focused on relay basedconcepts are proposed. Further the concept of an radio and protocol architecture is presented that takes upthe relaying approach as well as the idea of having different WINNER radio interface modes to servedifferent user and usage scenarios in an optimal manner. Thereby the presented protocol concept is basedon generic and mode specific user an control plane functionalities, where the common functions fordifferent modes are generalised and provide a common interface towards upper layer functions/protocols.Further some relaying concepts for urban hot area coverage including mesh networks are presentedaccompanied by promising simulation results. In addition to the relaying concepts benchmarks have beenproduced to allow a comparison of new concepts against today’s systems.

EU FP6 IST-2003-507581 WINNER, D3.2 Description of identified new relay based radio network deployment
- 2005
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Following the WINNER vision of a ubiquitous radio system providing wireless access for a wide range ofservices and applications across all environments D3.2 has consequently continued the work of D3.1towards a WINNER deployment concept. To cover the requirements of a WINNER RAN the flexiblenode architecture has been further elaborated. The envisaged WINNER modes are taken into account bymulti-mode protocol architecture that allows to exploit commonalities between different modes leading toa very flexible protocol and a close integration of the WINNER modes.The first steps towards concepts harmonisation are presented by categorising the large number ofdeployment concept proposals coming from D3.1 into logical groups. Further results on the comparisonbetween single-hop and multi-hop are shown in D3.2 accompanied by the presentation and assessment ofrelated routing strategies. Also the cooperative relaying concept has been driven forward and new resultshave been achieved in this field.Next to multi-hop, the single hop based deployment concepts have been elaborated partly with respect tonew air interface technologies. Finally D3.2 describes a system level simulation methodology to simulatethe deployment concepts based on the new WINNER air interface taking the agreed scenarios intoaccount.

On the needs and requirements arising from connected and automated driving
- 2020
-
Ingår i: Journal of Sensor and Actuator Networks. - : MDPI AG. - 2224-2708. ; 9:2
-
Tidskriftsartikel (refereegranskat)abstract
- Future 5G systems have set a goal to support mission-critical Vehicle-to-Everything (V2X) communications and they contribute to an important step towards connected and automated driving. To achieve this goal, the communication technologies should be designed based on a solid understanding of the new V2X applications and the related requirements and challenges. In this regard, we provide a description of the main V2X application categories and their representative use cases selected based on an analysis of the future needs of cooperative and automated driving. We also present a methodology on how to derive the network related requirements from the automotive specific requirements. The methodology can be used to analyze the key requirements of both existing and future V2X use cases.

EU FP7 INFSO-ICT-247223 ARTIST4G, D3.4 Relay configurations
- 2011
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- The following document contains proposals for innovations on relay configurations made by partners involved in the Artist4G project WP3, Task 3.3. The different relay configurations are for in-band and out-band relays, multi-hop relays, and moving relays. For each innovation, a description, the potential deviation from a defined baseline architecture, and simulation results (as far as available) are included. Important issues regarding the innovations impact on the architecture are pointed out and analysed in detail. This analysis will also be forwarded to WP4.

Performance Evaluation of Memory-less and Kalman-based Channel Estimation for OFDMA
- 2009

Ingår i: VTC Spring 2009 - IEEE 69th Vehicular Technology Conference; Barcelona; Spain; 26 April 2009 through 29 April 2009. - 1550-2252. - 9781424425174 ; , s. Art. no. 5073788-

Konferensbidrag (refereegranskat)abstract
- The next generation wireless systems based onOrthogonal Frequency Division Multiple Access (OFDMA) needto operate in widely different deployment and usage scenarios. Thus, support for flexible resource allocation is important. In this paper we investigate the performance of different memory-less and memory-based channel estimators with different OFDMA subcarrier allocation schemes and different pilot patterns. We evaluate the performance in various fading environments and for different user terminal velocities. The results show that channel estimation can perform well enough for time-frequency localized resources as small as 22 channel symbols with two pilots in many important scenarios. The results provided can be used to identify appropriate subcarrier allocations for the next generation OFDMA based wireless systems.
