The WINNER beyond 3G Air-Interface: A First Outline.
2nd COST 289 Workshop
, Antalya, Turkey, July 6-7 2005.
The IST-WINNER (Wireless World Initiative New Radio)
integrated project is a consortium of 38 partners
co-ordinated by Siemens working towards enhancing
the performance of mobile
communication systems. The improvements of radio
transmission to be explored by WINNER are crucial
for enabling new mobile services and applications
anytime and anywhere.
The aim is to design a radio interface architecture that
is efficient yet flexible, and can be used in wide area
coverage, metropolitan area systems, hot-spots as well
as indoor systems. The target peak aggregate bit-rates
are 100 Mbps for new mobile access and up to 1 Gbps for
new nomadic /local area wireless access.
One of several important challenges is to
simultaneously attain high spectral
efficiency and easy deployment.
Key system elements that are combined in different
ways in various deployment scenarios are
- link and system adaptation on different time-scales
- multi-antenna transmission as a basic design element,
rather than an add-on
- relaying, to extend the transmission range and
re-distribute the capacity over the cell area.
WINNER is as present 18 months into its first 2-year phase
2004-2005. The output of this first work is a system concept.
The talk will give a snapshot of the current thinking
within the project and the method we use working towards this goal.
The output of a planned WINNER phase II is intended to be
an optimized system proposal. WINNER is also providing
significant input to the process of assigning new spectrum,
with decisions planned in 2007.
