Project Description

Multipoint Communication

CCSL is targeting key areas of research that will play a vital role in the evolution of today’s heterogeneous networks into a distributed intelligent, highly flexible connectivity infrastructure. We believe that this evolution can only be achieved through the development of Multipoint Communication Schemes that can be extended to multiple networks in a HetNet environment.  Therefore, our ongoing research efforts are mainly focused on:

Coordinated Multipoint Communication Schemes that facilitate the evolution towards an Intelligent, Highly Flexible Connectivity Infrastructure

  • Towards this goal we have developed, for LTE-A networks, Coordinated Multipoint Communication Schemes (network MIMO) that dynamically select which and how many transmission points (TPs) will be utilized for each user at each transmission interval (TI) [1], [2] and [3]. These schemes are aware of the backhaul load, energy consumption, interference and spectrum utilization.
  • Furthermore, the virtualization of network resources is expected to be a key element in the transition to an integrated environment of heterogeneous networks. Hence, we studied hybrid resource sharing schemes for virtual wireless networks [4] extending our previous works on the integration of heterogeneous networks [5], [6], [7].
  • Zero perceived latency, a key feature of future networks, can also be aided by the use of cooperative transmission schemes. By incorporating latency as a structural metric in the TP selection process we can apply dynamic load balancing techniques on a per-TI basis. Moreover, cooperative transmission schemes, can be combined with latency-driven packet schedulers [8], [9], able to optimally distribute latency not only among the different services of each user as well as among different users.
