Submission of initial 5G description for IMT-2020

January 24, 2018

By Giovanni Romano, 3GPP ITU-R Ad Hoc group coordinator, TIM

Following the ITU-R Workshop on IMT-2020 terrestrial radio interfaces, in October 2017, 3GPP groups are now working on the initial description of the 3GPP 5G solution - based on LTE evolution and the first 5G NR specifications approved in December - has now been sent over to the ITU in accordance with the IMT-2020 submission and evaluation process.

The editors of the Initial “Description template of 3GPP 5G candidate for inclusion in IMT-2020”: (Wu Yong, Huawei and Asbjorn Grovlen, Ericsson) have provided a summary of the technical characteristics of the 3GPP 5G solution.

System architecture milestone of 5G Phase 1 is achieved

December 21, 2017

By Frank Mademann, 3GPP SA2 Chairman

The past two years have seen the 3GPP 5G architecture work progressing from the study period in 2016 to the delivery of a complete set of stage 2 level specifications. By achieving this milestone in 3GPP Release 15 the 5G system architecture has been defined - providing the set of features and functionality needed for deploying a commercially operational 5G system.

MCPTT tests to be hosted by TAMU, Texas

February 16, 2018

News published by Mission Critical Communications

The second MCPTT Plugtests event will be hosted by Texas A&M University (TAMU) June 25 – 29 in College Station, Texas, USA. The goal of the MCPTT Plugtests event is to validate the interoperability of different mission-critical push-to-talk (MCPTT) implementations on the market using different scenarios and test cases.

MCPTT was specified in 3GPP Release 13. 3GPP Release 14 added mission-critical data (MCData) and mission-critical video (MCVideo).

Interoperability and mission-critical service harmonization are critical challenges to be taken into account for the successful deployment and operation of mission-critical communications. The interoperability of MCPTT, MCData and MCVideo products and services has not been previously tested in the U.S.

5G device certification

January 26, 2018

The Global Certification Forum issued a press release this week, about their initial certification work for 5G devices based on 3GPP Release 15 specifications – for both Non-Stand Alone and Stand Alone 5G NR operation.

The news release details how GCF 5G conformance testing will draw on test cases defined by 3GPP’s RAN5 Working Group, with a new “umbrella Work Item” established to oversee the various areas for which conformance test cases are needed, such as radio reception, transmission and performance; radio resource management (RRM); positioning; radio access protocols; core network protocols and IMS protocols.
