5G Advanced: Evolution towards 6G

 5G Advanced: Evolution towards 6G


⏩ In 5G Advanced, the 5G new radio (NR) and 5G core (5GC) evolution is being continued to ensure the success of deployed systems globally and to expand the usage of the 3GPP technology by supporting different use cases and verticals.

⏩ Sustainable network design is one of the cornerstones of the 5G Advanced system. Artificial intelligence (AI) and machine learning (ML) will play an important role in addition to other technology components providing support for extended reality (XR), reduced capability (RedCap) devices, and other new market segments.

⏩ While Ericsson 5G networks already support AI/ML and XR use cases in an energy-efficient manner, 5G Advanced offers standardized solutions for enhancing performance and enabling a new types of applications for these use cases. The 5G Advanced standardization is an important step in the evolution of cellular wireless access toward 6G.

⏩ This whitepaper provides an overview of 5G Advanced to show the main advantages of its technology components regarding network performance and capabilities. Guidance is provided on which features to expect in 5G Advanced Release 18 and 19 and it is explained how 5G Advanced provides steppingstones towards 6G.

⏩ 3GPP Release 18 marks the start of 5G Advanced. 5G Advanced builds on the 5G baseline defined by 3GPP in Releases 15, 16, and 17. Further enhancement of the 5G Advanced system is expected in the forthcoming Release 19 which will start in 2024.

⏩ Initial learnings have been derived from commercial 5G networks that have been deployed in large parts of the world. In addition to this, the need for the continuous evolution of 5G networks by supporting new market segments and use cases has prompted 3GPP to begin standardization related to 5G Advanced systems. 5G Advanced also provides steppingstones in areas that will be of importance in the future 6G systems.

⏩ This white paper provides an overview of 5G Advanced with a special focus on its most vital pillars. The main technology components and their use cases are discussed in addition to 3GPP’s future direction towards 6G.

⏩ After initial studies, standardization of the new 6G system may officially start from Release 21. Figure 1 provides Ericsson’s view of the 3GPP’s 5G Advanced and 6G timeline indicating completion of the first 5G Advanced release in the beginning of 2024 and completion of the first (basic) 6G drop in 2028, followed by 6G evolution.

Malaysia set to roll out second 5G wholesale network

Malaysia set to roll out second 5G wholesale network The current state of Digital Nasional Berhad's (DNB) leadership does differ from its initial structure. As of today, January 15, 2024: No Chairman: The position of Chairman has been vacant since April 2023, following the resignation of the previous chairman. Two Board Members: Currently, DNB has only two remaining board members. This is significantly smaller than the planned size of the board, which was initially set at seven members. This situation has raised concerns about potential governance issues and a lack of strong leadership at DNB. Some stakeholders argue that the absence of a full board and chairman could hinder the decision-making process and negatively impact the rollout of 5G infrastructure in Malaysia. The government has acknowledged these concerns and has assured the public that they are actively searching for qualified candidates to fill the vacant positions. However, there is no official...
