The growing demand for improved performance in cellular radio networks led to the investigation of novel techniques able to cope for these needs. One of the most promising, currently evaluated in the framework of standardization bodies following ITU-R process for IMT-Advanced, is the so-called Coordinated MultiPoint (CoMP) access network architecture and related approaches and algorithms. CoMP is one of the most extensively studied topics in the context of Winner+ CELTIC European project. CoMP brings forward the concept of Advanced Antenna systems, introducing a degree of collaboration among a multiplicity of nodes exchanging information among them. Consequently, CoMP aims to exploit concurrently signals coming from all the nodes, transforming inter-cell interfering signals in useful ones, especially for cell-border users. In this paper some possible CoMP architectures are listed and the first results of simulations on CoMP systems, starting from ideal assumptions, are reported.

Nyckelord: CoMP, coordinated antennas, advanced antenna systems, LTE-Advanced, Winner+, Interference, Inter-cell and/or intra-cell interference, MIMO, Network MIMO, RoF, Relaying
