Abstract
Proposed technologies in current paper are intended to revolutionize the way in which the radio spectrum is being managed in current wireless networks. The proposed methods as ultimate efficient ways of handling spectrum can be seen as a bridge between current legacy systems (Beyond 3GPP LTE, WiMAX) and future cognitive radio networks. In this paper, we consider the IST WINNER European radio network design and outline key additive and complementary technologies to WINNER architecture to achieve further improvements in wireless networks. On a cooperative basis, the proposed technologies open the way for a more flexible exploitation of radio spectrum resources while significantly improving the spectral efficiency and availability. It introduces the novel concepts for short term spectrum assignment in wireless radio networks leading to fast scheduling of spectrum with significant impact on all the relevant radio networks layers. This can be seen even more important than the introduction of fast Base Station (BS) based scheduling in an HSDPA system during late 90's. © 2008 IEEE.
