From Wikipedia, the free encyclopedia
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]
On February 1, 2021, the standard was published as
Recommendation ITU-R M.2150-0
titled
Detailed specifications of the radio interfaces of IMT-2020
,
[2]
but most of it was finalized years earlier.
[3]
For example the requirements for
radio access technologies
listed below were adopted in November 2017.
[4]
Following the publication of the requirements the developers of radio access technologies such as
3GPP
and
ETSI
are expected to develop 5G technologies meeting these requirements. 3GPP is developing radio access technologies
5G NR
,
LTE-M
and
NB-IoT
that together are expected to meet all requirements,
[5]
while ETSI is developing
DECT-2020
NR and Nufront is developing
EUHT
(Enhanced Ultra High Throughput).
Requirements

The following parameters are the requirements for IMT-2020 5G candidate
radio 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.
