Integrated Sensing and Edge AI: Realizing Intelligent Perception in 6G
The sixth-generation (6G) mobile networks are poised for a remarkable evolution, integrating sensing and edge artificial intelligence (AI) to enable advanced perception tasks. This paradigm, termed Integrated Sensing and Edge AI (ISEA), offers a holistic design approach to communication, AI computation, and sensing for optimal task performance. ISEA addresses critical challenges in latency, reliability, and data volume, moving beyond conventional connectivity-centric models. It emphasizes modality-aware data communications, integrated communication-computing, and task-oriented optimization. This survey provides a comprehensive overview of ISEA's technical preliminaries, use cases, design principles, architectures, and enabling techniques, along with future research opportunities in foundation models, ISAC convergence, and ultra-low-latency applications.

Joint Source-Channel Coding (JSCC)
JSCC pushes the limits of separated source-channel coding, overcoming drawbacks like the cliff effect in 6G scenarios. DL-empowered JSCC uses neural networks for E2E optimization of downstream tasks, like maximizing object detection precision instead of just minimizing reconstruction error. This allows for task-oriented communication, adapting to sensory data semantics and importance, and improving efficiency under stringent QoS requirements.
Over-the-Air Computation (AirComp)
AirComp leverages the waveform superposition property of wireless channels for low-latency data aggregation. It enables computation of aggregation functions (e.g., averaging, max-pooling) by simultaneous transmissions from multiple devices. In ISEA, AirComp is vital for efficient aggregation of sensory data and intermediate AI results, tolerating moderate errors due to AI model robustness, and scaling with O(1) latency regardless of the number of devices.
Edge Learning & Inference
Edge AI is crucial for low-latency, high-reliability sensing tasks. Edge learning, often via federated learning (FL), distributes model training to local sensors to avoid raw data transmission, addressing privacy and communication bottlenecks. Edge inference deploys trained AI models on edge nodes close to devices, reducing latency and backbone traffic for real-time applications like autonomous driving. Split inference, a prevalent approach, divides models between devices and servers to balance computation and communication.
Multi-Modal Sensing
ISEA integrates various sensing modalities like LiDAR, cameras (RGB/RGB-D), RF sensing, and event cameras. Each has unique advantages and limitations (e.g., LiDAR for 3D spatial info, cameras for rich semantics, RF for non-LoS). Multi-modal fusion combines complementary features to boost sensing performance, with fusion strategies occurring at raw data, feature, or decision levels. Communication cost is a critical factor in distributed multi-modal fusion.

Autonomous Driving with ISEA
Autonomous driving requires real-time, intelligent, and reliable perception and decision-making. ISEA is indispensable, enabling vehicles to fuse multi-modal sensory data (LiDAR, cameras, RF sensing) and execute AI models at the edge for tasks like object detection and localization. Cooperative ISEA, involving V2V and V2I communication, overcomes occlusions and extreme weather by sharing sensory information in a shared feature space, ensuring robust environmental awareness under stringent latency and reliability demands. This orchestration of AI computation and sensory data communication is critical for next-level autonomous capabilities.
