Phase 1 – mid 2018
  • Focus on eMBB and low latency aspects
  • Minimized changes to core architecture (LTE-EPC) – NSA operation initially
  • 5G RAT - focus on “conventional” frequency channels
Phase 2 – mid 2020
  • Focus on mMTC and URLLC
  • Novel layers and architecture to allow full 5G potential (vehicular and multicast services)
  • “mmWave” 28, 37, 39 GHz channels and unlicensed spectrum
Release 15

While initial specifications enabled non-standalone 5G radio systems integrated in previous-generation LTE networks, the scope of Release 15 expands to cover ‘standalone’ 5G, with a new radio system complemented by a next-generation core network. It also embraces enhancements to LTE and, implicitly, the Evolved Packet Core (EPC). This crucial way-point enables vendors to progress rapidly with chip design and initial network implementation during 2019.

Release 15 were approved and frozen, adding the standalone mode for 5G NR to the already approved non-standalone mode.

Next on the agenda is Release 16, scheduled for the end of 2019, which will add standards for the remaining use case scenarios, such as massive machine type communications.

Release 16

In addition to that formal process, work has started on around 25 Release 16 studies, on a variety of topics: Multimedia Priority Service, Vehicle-to-everything (V2X) application layer services, 5G satellite access, Local Area Network support in 5G, wireless and wireline convergence for 5G, terminal positioning and location, communications in vertical domains and network automation and novel radio techniques. Further items being studied include security, codecs and streaming services, Local Area Network interworking, network slicing and the IoT.
