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 required).
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.
Artificial Intelligence and Machine Learning
By Gino Masini, Yin Gao, Sasha Sirotkin (Article first published in HIGHLIGHTS Issue 02, March 2021).
Title: Artificial Intelligence and Machine Learning in NG-RAN: New Study in RAN3.
5G brings more stringent requirements for Key Performance Indicators (KPIs) like latency, reliability, user experience, and others; jointly optimizing those KPIs is becoming more challenging due to the increased complexity of foreseen deployments. Operators and vendors are now turning their attention to Artificial Intelligence and Machine Learning (AI/ML) to address this challenge. For this reason, following RAN plenary approval, 3GPP RAN3 has recently started a new Release-17 study on the applications of AI/ML to RAN.
Release 17 Update from SA2
By Puneet Jain, 3GPP Working Group SA2 Chair (Article first published in HIGHLIGHTS Issue 02, March 2021).
Technical Specification Group SA Working Group 2 is in charge of developing the Stage-2 specifications of the overall system architecture - including the main functions and entities of the 3GPP network, how these entities are linked to each other and the information they exchange.
The group defined the 5G system architecture as part of 3GPP Release-15 and has continued its progress with the Release-16 work - focusing on following key focus areas:
