Evolution towards 5G-Advanced

May 11, 2021

Following his appointment to the RAN Chair, Wanshi Chen has laid out his immediate priorities for the year and for meetings well into 2022 - In a recent ETSI webinar. He has also unveiled the preliminary topics of a June 2021 Workshop on Release 18 – With submissions to be divided into three areas (preliminary agenda): eMBB driven work, Non-eMBB driven functionality and Cross-functionality for both.

The webinar, recorded on May 5, 2021, is now available on the 3GPP Vimeo site: https://vimeo.com/548457634 (no registration reqired).

Release 17 on time

Wanshi Chen acknowledged that Release 17 - the third release of 5G specifications - has been under pressure due to COVID-19 restrictions, but despite making the move to e-meetings, he reported that the group’s experts have managed to ensure positive progress towards the freeze of the RAN1 physical layer specifications on schedule, by December 2021.

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.
