Interference Mitigation Framework for Cellular Mobile Radio Networks

Abstract EN

For today's cellular mobile communication networks, the needed capacity is hard to realize without much more of (expensive) bandwidth.

Thus new standards like LTE were developed.

LTE advanced is in discussion as the successor of LTE and cooperative multipoint transmission (CoMP) is one of the hot topics to increase the system's capacity.

System simulations often show only weak gains of the signal-to-interference ratio due to high interference from noncooperating cells in the downlink.

This paper presents an interference mitigation framework to overcome the hardest issue, that is, the low penetration rate of mobile stations that can be served from a cluster composed of their strongest cells in the network.

The results obtained from simulation tools are discussed with values resulting from testbed on the TU Dresden.

They show that the theoretical ideas can be transferred into gains on real systems.
