URLLC Ultra Reliable Low Latency Communication
URLLC is one of the three facets of 5G, alongside MMTC (Massive Machine Type Communication) and eMBB (enhanced Mobile Broadband). In particular, URLLC features two parts; ultra-reliability which constitutes network reliability of beyond 99.999%, coupled with very low latency for packet transmission (in the order of 1ms and below). Note that the two are mutually exclusive in that some services will require both ultra-reliability and low latency, whereas other services may require one or the other.
