The Third-Generation Partnership Project (3GPP) has endorsed a tentative timeline for the standardization of next-generation cellular technology, also known as fifth-generation (5G). 3GPP is committed to submitting a candidate technology to the International Mobile Telecommunications (IMT) 2020 process triggered by International Telecommunications Union Radiocommunication Sector (ITU-R). From the perspective of IMT 2020, the key constraints are given by the following two submission deadlines: the initial technology submission by ITU-R Working Party 5D (WP5D) meeting 32 in June 2019 and the detailed specification submission by ITU-R WP5D meeting 36 in October 2020.
For the latter deadline, 3GPP has decided to submit the final specifications at the ITU-R WP5D meeting in February 2020, based on the functionally frozen specifications available in December 2019. This early submission should allow enough time for the transposition of the specifications by the organizational partners of 3GPP prior to their own submissions into the IMT 2020 process before October 2020. Tentatively, the radio access network (RAN) study will be approved in December 2015. The RAN study may remain formally open until the corresponding ITU-R task is closed. During the study, RAN will import the relevant IMT 2020 requirements and add its own requirements. The study will include operation above 6 GHz.
