5G-Advanced, formally defined in 3GPP Release 18, represents an upgrade to existing 5G networks. 先睹robot总结的5G Advanced的advancements:
-
Enhanced Mobility and Reliability:
- 5G-Advanced will support advanced applications with improved mobility and high reliability. Whether you’re on the move or in a fast-moving vehicle (like a train or plane), the connectivity experience will be seamless.
-
Artificial Intelligence (AI) and Machine Learning (ML):
- AI and ML will play a significant role in 5G-Advanced. These technologies will enhance network performance, optimize resource allocation, and improve overall efficiency.
-
Spectral Efficiency and Energy Savings:
- Expect further improvements in spectral efficiency, which means better utilization of available radio spectrum. Additionally, energy-saving features will contribute to a more sustainable network.
-
Smart Connectivity for Uplink Communication:
- 5G-Advanced will provide smart connectivity for uplink communication. This is crucial for scenarios where people are moving at high velocities, such as passengers on trains or airplanes.
-
Highly Immersive and Interactive Applications:
- The technology will efficiently support immersive applications widely deployed in entertainment, training, and education sectors. Think of augmented reality (AR), virtual reality (VR), and other interactive experiences.
-
Bridging to 6G:
- 5G-Advanced will serve as a stepping stone toward 6G. It will introduce features not previously standardized in 3GPP, setting the stage for future advancements¹³.

摘截R18 接入技术(RAN)的新特性和新需求如下。一方面5G+提出了增强传统移动通信指标的要求,如移动性(mobility),可靠性(reliability)以及覆盖(coverage)等。另一方面5G+意在搭建智能的、经济的生态网络环境,强调运用ML技术、节约能源(network)和功耗(UE)、以及NTN的增强等。同时也能看出对uplink(Tput,coverage,power,etc.)的增强是落实R18的重要环节。
