3GPP Publishes Update to Release 19 Specification
The 3GPP standards body has published an update to Technical Specification 23.008 (v19.0.0). This specification refines protocols for packet-switched network access modes and core network functions. The update is part of the ongoing 3GPP Release 19 standardization cycle, which continues to be a key venue for influence among major telecommunications vendors.
- Release 19 is positioned as the final major evolution of 5G-Advanced and a critical bridge to 6G, with the functional freeze of its features anticipated by the end of 2025. It will be followed by Release 20, which will formally kick off 6G studies. - A key focus is the specification of a general framework for Artificial Intelligence and Machine Learning (AI/ML) in the air interface, building on studies from Release 18. This framework will initially support use cases in beam management, positioning, and Channel State Information (CSI) prediction, with companies like Qualcomm actively demonstrating these capabilities. - Enhancements to massive MIMO (Multiple-Input Multiple-Output) will improve multi-user support, allowing more devices to share the same resources. The release also advances toward fully distributed MIMO (D-MIMO) systems by enabling more cost-efficient distributed transmitters and receivers. - The specification continues to build out support for Non-Terrestrial Networks (NTN), with a focus on improving satellite downlink coverage and introducing support for more device types, including RedCap (Reduced Capability). This work reflects the growing integration of satellite and terrestrial networks within a single standard. - Geopolitically, the work in Release 19 is a precursor to more intense competition over 6G standards. Within 3GPP, for instance, some Chinese telecommunication stakeholders have advocated for a completely new 6G core network, while other members favor an evolution of the existing 5G Core. - China’s IMT-2030 (6G) Promotion Group is a central coordinating body for its national strategy, and the country has already allocated the 6425-7125 MHz spectrum for 5G and future 6G use to influence global spectrum harmonization. - Release 19 includes early technical studies foundational to 6G, such as channel modeling for upper mid-band spectrum (7-24 GHz) and for Integrated Sensing and Communication (ISAC), indicating where the next generation of network technology is headed.
