Coordinated multi-cell resource allocation for 5G ultra-reliable low latency communications

The coming 5G cellular communication system is envisioned to support a wide range of new use cases on top of regular cellular mobile broadband services. One of the 5G usage scenarios is ultra-reliable low-latency communications (URLLC). It has been predicted that URLLC will play an essential role in enabling wireless communications for emerging new services and applications such as factory automation, remote manipulation, autonomous driving and tactile Internet, to name a few. The two key performance metrics related to URLLC are latency and reliability. In this paper three coordinated multi-cell resource allocation methods for 5G URLLC are presented in a typical indoor environment. From the simulation results, it can be observed that handling inter-cell interference effectively can lead to a significant performance improvement in terms of reliability without bringing any degradation to the latency performance.
