IMT-2020 towards 'Beyond'

Interview with Sergio Buonomo, Chief, ITU-R Study Groups Department (Article first published in HIGHLIGHTS Issue 02, March 2021).

The ITU-R has recently published their Recommendation ITU-R M.2150 entitled: 'Detailed specifications of the radio interfaces of IMT-2020', listing the specifications that conform with its requirements for 5G operation.

We invited Sergio Buonomo to answer a few questions, intended to help the 3GPP readership to better understand how our own specifications for 5G are connected to the ITU’s IMT-2020 process.

Highlights: Could you sum up the significance of the IMT process and what it means to conform to it?

SB: The ITU-R is responsible for the Radio Regulations, with the latest set being the 2020 version, which is the essential regulatory document for the service allocation of the frequency bands (8.3 kHz - 275 GHz Range). They define the spectrum allocation for all radiocommunication services in the three ITU-R Regions, including the allocation for the mobile service. Also, there are important “footnotes” in there; defining the identification of IMT in frequency bands for specific countries.


CCSA's Zemin Yang announces his retirement

May 4, 2021

At the recent China Communications Standards Association (CCSA) Board meeting, on April 11, the highly respected Zemin Yang announced his retirement from the post of CCSA Secretary-General. For the past ten years, Zemin Yang has brought grace and expertise into this leadership position - Qualities felt most directly here through his participation in the 3GPP Project Coordination Group (PCG) and the Organizational Partner (OP) meetings.

In his farewell address to PCG he touched on his vision for 3GPP, as an example of positive cooperation. He told colleagues that he felt lucky to have been in the 3GPP family at a time of great importance; “fulfilling our responsibilities to our respective organizations and to 3GPP.” He concluded: “In particular, I should say that whether we agree upon everything or not, we have always been able to treat each other frankly and sincerely, with understanding and real respect. My experience at 3GPP has given me a very fulfilling and enjoyable decade in my career.”


5GAA study of spectrum needs for safety related ITS

April 2021 (5GAA Study dated 25/6/2020)

By Reza Karimi (Huawei, UK), Markus Mueck (Intel, Germany), Yan Li (Qualcomm, China), Stefano Sorrentino (Ericsson, Sweden) - Article first published in HIGHLIGHTS Issue 02, March 2021.

5GAA has conducted a study in relation to the spectrum needs of use cases for intelligent transport systems (ITS) and advanced driving as implemented by cellular V2X (C-V2X) technologies.

Starting from a list of over 40 use cases, we first categorise these as “initial/day-1” or “advanced”. It is the view of the 5GAA that LTE-V2X and NR-V2X are the most suitable technologies for the support of day-1 ITS and advanced driving use cases, respectively. We subsequently classify these as

  • use cases which involve direct communications among road users or between road users and ITS roadside infrastructure (so-called V2V, V2I, V2P) as supported by the C-V2X (PC5) interface in the 5.9 GHz band harmonised globally for ITS, and
  • use cases which involve network-based communications between road users and mobile network base stations (so-called V2N) as supported by the C-V2X (Uu) interface in bands designated and licensed for use by mobile communication networks,

where the term “road user” includes vehicles and pedestrians.


Media Production over 5G NPN

April 23, 2021 (update)

3GPP Market Representation Partner - The 5G Media Action Group (5G-MAG) has completed its workshop “Media Production over 5G Non-Public Networks”, around the objectives of a new 3GPP study on the topic.

Videos and the presentations from the workshop are now available for viewing on the 5G-MAG website.


Serving up interoperability for railway communications

April 15, 2021

ETSI have announced that its Future Railway Mobile Communication System (FRMCS) Plugtests will soon be arriving on their platform.

The remote event, 14 -18 June 2021, will validate equipment interoperability using test scenarios based on the 3GPP Mission Critical work - with its focus on the rail specific features, testing for railways-oriented capabilities like Functional Aliases, Multi-talker and MCData IP Connectivity.

The event will use Over-The-Top (OTT) tests via VPN connections from the vendor labs. The tests will be based on 3GPP, ETSI and IETF standards, and are designed for the following equipment:
