5G Ultra Reliable Low Latency (URLLC) as standardized in 3GPP Release 15/16 is the key enabler for critical wireless low-latency communication in industrial uses such as port automation and smart grid. 5G URLLC offers simultaneous low-latency and high reliability communication links with down to 1ms one-way delay and 10-5 packet error rate. To achieve these goals, several new radio interface procedures have been specified – for example shorter sub-millisecond transmission and scheduling intervals, pre-emptive multiplexing between enhanced Mobile Broadband (eMBB) and URLLC traffic and grant-free transmissions on uplink. In 5G VIIMA we developed prototypes and test beds for evaluation of URLLC radio link performance for both laboratory and field trial environments (see also Remotely-controlled RTG cranes). Furthermore, extensive system level simulations were done to assess the performance of 5G URLLC in a realistic multi-cell port automation environment. These simulations were based on realistic radio propagation measurements on Kalmar test yard. Both the laboratory measurements and system level simulation results were very promising for providing wireless port automation over 5G even with much more stringent latency requirements than what is currently needed.
