Interference coordination in ultra-reliable and low latency communication networks

Abstract

5th Generation cellular communication is envisioned to enable connectivity for a wide range of new use cases. The focus on mission-critical communications, such as industrial automation and motion control, presses the demand for ultra-reliable communication. High availability, e.g., 99.999 % can be strived to reduce the outage probability. However, in multi-cell networks, interference from neighboring cells can be damaging in the ultra-reliable communication region. This requires a coordination amongst the interfering cells to relieve the interference in order to improve the network availability. In Multiple-Input, Multiple-Output based networks where the interference is colored, multiple base stations can coordinate by precluding the usage of precoders that increases the overall interference strongly. With this, multiple cells can jointly improve the minimum cell rate without inflicting harm to the other cell users, and thereby improve the network availability.
