A multi-user spatial domain link adaptation concept for beyond 3G systems

This paper summarizes current work within the IST-Project WINNER (Wireless World Initiative New Radio) towards a spatial processing solution as an integral part of the overall system concept. Major requirements for the WINNER multi-antenna concept include high performance, robustness, and adaptation to a wide range of scenarios and terminal classes, as well as efficient interworking with the basic transmission and network concept. Based on these guidelines, a first proposal for the WINNER multi-antenna concept is elaborated upon and presented in the form of a generic downlink transmitter that will serve as baseline for further investigation and system integration
