Refined Radio Innovation Areas for IMT-Advanced Within the WINNER+ Project

Free registration required

Executive Summary

This paper summarizes the latest candidate techniques for IMT-Advanced and beyond investigated in the WINNER+ project. The presented techniques cover five innovation areas: Advanced Antenna Systems (AAS), Advanced Radio Resource Management (ARRM), Relaying, Coordinated MultiPoint (CoMP) transmissions and Spectrum Technologies. In AAS, under the framework of cellular multiuser MIMO systems, the proposals focus on how to make the CSI available at the transmitter and to reduce the pilot overhead. Within the CoMP transmissions, coordinated scheduling and/or beamforming and joint processing/transmission are briefly presented and analyzed.
