IMT-2020

International Mobile Telecommunications-2020 (IMT-2020 Standard) are the requirements issued by the ITU Radiocommunication Sector (ITU-R) of the International Telecommunication Union (ITU) in 2015 for 5G networks, devices and services.[1]

The standard is expected to be completed in 2020,[2] but parts of it have been finalized earlier. For example the requirements for radio access technologies listed below were adopted in November 2017.[3] Following the publication of the requirements the developers of radio access technologies such as 3GPP were expected to develop 5G technologies meeting these requirements. 3GPP is developing radio access technologies NR, LTE-M and NB-IoT that together are expected to meet all requirements.[4]

Requirements

The following parameters are the requirements for IMT-2020 5G candidate radio access technologies.[5] Note that these requirements are not intended to restrict the full range of capabilities or performance that candidate for IMT-2020 might achieve, nor are they intended to describe how the technologies might perform in actual deployments.

Capability Description 5G requirement Usage scenario
Downlink peak data rate Minimum maximum data rate technology must support 20 Gbit/s eMBB
Uplink peak data rate 10 Gbit/s eMBB
User experienced downlink data rate Data rate in dense urban test environment 95% of time 100 Mbit/s eMBB
User experienced uplink data rate 50 Mbit/s eMBB
Latency Radio network contribution to packet travel time 4 ms eMBB
1 ms URLLC
Mobility Maximum speed for handoff and QoS requirements 500 km/h eMBB/URLLC
Connection density Total number of devices per unit area 106/km2 mMTC
Energy efficiency Data sent/received per unit energy consumption (by device or network) Equal to 4G eMBB
Area traffic capacity Total traffic across coverage area 10 Mbps/m2 eMBB
Peak downlink spectrum efficiency Throughput per unit wireless bandwidth and per network cell 30 bit/s/Hz eMBB
