The initial 5G 3GPP Release (Release 15) targeted applications in three service categories – enhanced mobile broadband (eMBB), ultra-reliable low latency communications (uRLLC) and the low-throughput and battery-efficient massive machine-type communication (mMTC), as defined by the ITU Radiocommunication Sector’s IMT-2020 specification. After the commercial roll-out of numerous 5G networks across the globe, a need has emerged for a variant of 5G in which the performance and costs are optimised for use cases that fall in-between these initial service categories.
