International Mobile Telecommunications-2020 (IMT-2020 Standard) are the requirements issued by theITU Radiocommunication Sector (ITU-R) of theInternational Telecommunication Union (ITU) in 2015 for5G networks, devices and services.[1]
On February 1, 2021, the standard was published asRecommendation ITU-R M.2150-0 titledDetailed specifications of the radio interfaces of IMT-2020,[2] but most of it was finalized years earlier.[3] For example the requirements forradio access technologies listed below were adopted in November 2017.[4] Following the publication of the requirements the developers of radio access technologies such as3GPP andETSI are expected to develop 5G technologies meeting these requirements. 3GPP is developing radio access technologies5G NR,LTE-M andNB-IoT that together are expected to meet all requirements,[5] while ETSI is developingDECT-2020 NR and Nufront is developingEUHT (Enhanced Ultra High Throughput).
The following parameters are the requirements for IMT-2020 5G candidateradio access technologies.[6] 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 |
