Pushed by the demand for bandwidth-hungry multimedia and internet-related wireless services, communication engineers seek to maximally exploit the spectral resources in all available dimensions.
Together with the increased density of base stations in cellular networks in the most populated areas, the aggressive reuse of frequencies planned in so called next generation cellular networks results in a novel situation where interference (along with the classical fading problem) is no longer just an issue but rather emerges as the key limiting factor.
As the many radio links sharing the resource in the network can no longer be treated as independent, the classical approach of individually optimizing communication over the point-to-point channels between a mobile and a base station, using say advanced codes, or single-link MIMO, must be revisited to offer a truly "multi-terminal” view of the network. At the core of this view, lies the notion of network coordination and cooperation which can take place between base stations, or even between the terminals themselves.
Although cooperative communications was until recently much associated with the notion of relaying, this concepts is now re-inventing itself to find its way into the cellular network framework, notably as a way to deal with interference using distributed MIMO concepts.
A powerful weapon against fading and interference, cooperative communication finds itself particularly well suited to the context and constraints of cellular communications because of pre-existing backhaul infrastructure linking the base stations together.
When infrastructure links do not exist or are saturated, the notion of Network Coordination has been proposed as a promising emerging alternative for dealing with interference. Coordination can take place is a variety of domains such as resource control, scheduling, beamforming, interference alignement, etc. and poses both new theoretical and practical challenges.
In this course we will review the fundamentals as well as the latest evolutions in network multicell cooperation and coordination research, including distributed interference control techniques allowed by the many antenna regime (so-called massive MIMO). Applications will be described along with the current status of discussion in key standards.
