IMT-2020
International Mobile Telecommunications-2020 are the requirements issued by the ITU Radiocommunication Sector of the International Telecommunication Union in 2015 for 5G networks, devices and services.
The standard is expected to be completed in 2020, but parts of it have been finalized earlier. For example the requirements for radio access technologies listed below were adopted in November 2017. 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.
Requirements
The following parameters are the requirements for IMT-2020 5G candidate radio access technologies. 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 |
