Since October 2014, 3GPP has been a
leading participant in the ITU-R process
to prepare the way for terrestrial radio
interface specifications for IMT-2020.

3GPP IMT-2020 PROPOSAL

The 3GPP “5G” final proposal includes two separate and independent submissions, defined as the single Radio Interface Technology (RIT)
and the combined Sets of Radio Interface Technologies (SRIT):
1
Submission 1: SRIT
• Component RIT: NR
• Component RIT: E-UTRA/LTE incl. standalone LTE, NB-IoT, eMTC, and LTE-NR DC)
2
Submission 2: RIT
• NR
Each submission is self-contained and complete unto itself, consisting of Releases 15 & 16

The 3GPP submissions are each collectively supported by the seven 3GPP Organizational Partners (Standards bodies; ARIB, ATIS, CCSA,
ETSI, TSDSI, TTA and TTC) following their approval of the following:
• An overview of the main radio characteristics.
• The Compliance Template, a self-assessment on the fulfilment of the IMT-2020 requirements.
• The Link Budget Template, providing useful information on cell radius and network planning.
• TR 37.910, providing an exhaustive analysis of 3GPP “5G”, including simulation assumptions and results performed in the self-assessment.
