Driven by increasing demands on connectivity to improve safety, situational awareness and operational effectiveness for first responders, more and more public safety agencies are realizing the need of modernization of their existing non-3GPP networks. 3GPP based cellular networks offer the unique opportunity of providing fast, reliable, and prioritized communications for first responders in a shared network. In this article, we give an overview of service requirements of public safety mission critical communications. We identify key technical challenges and explain how 5G NR features are being evolved to meet the emerging safety critical requirements, including enabling connectivity everywhere, supporting efficient group communications, prioritizing mission critical traffic, and providing accurate positioning for first responders.

  1. When 5G MIMO Scaling Breaks: Toward 6G Upper-Mid-Band Extreme MIMO

    eess.SP 2026-07 conditional novelty 5.0 of 10

    Scaling 5G MIMO to 256+ ports at 7–8 GHz breaks on common-channel coverage, RF/array power, and CSI overhead; the paper maps a roadmap that decouples radiating elements, RF chains, and acquired channel dimensions.
