Abstract
This paper contributes to the system concept of collaborative base stations from the perspective of distributed computing. Promising signal processing approaches based on terminal feedback are reviewed. Their specific advantages and disadvantages are discussed and a framework for feedback provision is presented. All proposed schemes have in common, that a mobile terminal can choose its desired receive strategy independently from other mobile terminals according to its computational capabilities. The effective multi-cell channel after receiver processing is fed back and distributed within the collaboration area. This allows distributed processing at each base station and makes real-time implementation feasible.
