ISAC Principles and Applications for 5G and 6G

ISAC Principles and Applications for 5G and 6G delivers a comprehensive, practical guide to integrated sensing and communication as it transitions from a research concept into a deployable 5G-Advanced and 6G network capability. This essential volume connects fundamental theory directly to real-world implementation, guiding readers from information-theoretic limits through 3GPP standardization, IEEE 802.11bf WLAN sensing, and Open RAN (O-RAN) integration. Starting with capacity-distortion and CRB-rate trade-off frameworks, the text thoroughly explores active sensing with OFDM and OTFS waveforms and passive sensing that exploits 5G SSB and PUSCH transmissions.

Moving beyond core concepts, the book examines advanced technical challenges, detailed channel modeling, and practical network deployments. Gain deep insight into 3GPP Release 19 sensing modes, target versus background channel decomposition, and radar cross-section modeling for UAV, vehicular, and human detection. Detailed coverage addresses physical hardware impairments, secrecy-sensing trade-offs in waveform design, 5G core sensing function architecture, and dApp-based real-time inference within O-RAN environments. Tailored specifically for wireless system engineers, standardization researchers, and graduate students in radar and communications, this reference provides actionable solutions for optimizing waveforms under real hardware limits, meeting 3GPP service KPIs, and integrating sensing directly into legacy communication infrastructure.

Combining cutting-edge research with field-proven commercial execution, this volume provides a single, unified reference for the technical specifications driving next-generation dual-functional networks. It directly links emerging standardizations with real-world deployment challenges across terrestrial and non-terrestrial architectures. Packed with detailed figures, worked examples, and reference tables, this text delivers the definitive engineering framework for designing, evaluating, and deploying next-generation ISAC systems.
