The European research project WINNER is a cooperation of 39 partners
from industry, operators, and academia, which is partly funded
by the European Union. It has the overall goal to develop a single
radio interface covering the full range from isolated hot spots
to wide area cellular scenarios by using different modes of a
common technology. It targets increased data rates, low latency,
and high system capacity based on adaptive transmission schemes,
flexible spectrum usage, relaying, and advanced multi-antenna
processing. The WINNER I project (2004-2005) evaluated
technologies and combined them into a system concept.
It forms the basis for the WINNER II project (2006-2007),
which aims at the design and detailed assessment of a beyond
3G system proposal.
The WINNER radio interface design is
aimed at attaining both high flexibility in terms of spectrum
use and fulfillment of user requirements and a high spectral
efficiency in different deployment and usage scenarios; two
goals that are often contradictory and difficult to combine.
The medium access control (MAC) system layer plays an
important role for fulfilling these goals. It performs tasks that
in existing systems are associated with Logical Link Control,
Medium Access Control and Radio Resource Control protocol (sub)layers.
The present paper focuses on the resource allocation problems
that are to be solved and outlines the time-frequency-spatial resource
units and control function blocks designed to solve them.
Detailed protocol aspects of the MAC system layer are not
discussed here, and are at present being developed within WINNER II.

Abstract:
- The European IST research projects WINNER
and WINNER II aim at developing a single new
ubiquitous radio access system concept that can be
adapted for use in a wide variety of mobile communication
scenarios, from wide area coverage to hot spots.
This cellular packet data system uses a multicarrier-based
air interface. Its medium access control (MAC) system
layer is designed for either FDD or TDD cellular transmission.
It supports adaptive transmission by tight interaction
with the physical layer, and provides efficient resource
allocation and scheduling within relay-enhanced cells.
It also supports separate allocation of antenna resources
per packet flow and furthermore provides support for
spectrum sharing and flexible spectrum use.
The paper outlines the resource allocation within a
super-frame and the use of either opportunistic
scheduling or diversity-based transmission within frames.
