Massive MIMO is a cornerstone of 5G cellular networks, unlocking unprecedented capacity in real networks through spatial multiplexing. Unfortunately, this performance enhancement comes at the cost of hardware inefficiency and power consumption. The philosophy behind Massive MIMO is to have an abundance of service antennas, e.g., 64 base station antennas to send 8 data layers, when 8 antennas would theoretically suffice. This overprovisioning isn’t accidental; it ensures favourable propagation conditions so that most user channels are compatible for spatial multiplexing, regardless of the channel environment. But if we continue to follow this philosophy when designing 6G systems operating in the upper mid-band, it will lead to unsustainable antenna counts. This calls for a new design paradigm. In this talk, we’ll explore a bold shift in multi-user MIMO design: achieving high capacity with fewer antennas per data layer. The key lies in smarter, site-specific antenna array architectures. We start from basic principles and gradually develop the new framework. By moving beyond conventional half-wavelength-spaced uniform arrays, we can unlock and combine the gains of sparse arrays, non-uniform antenna arrangements, transmissive intelligent metasurfaces, and even physically movable/fluid elements. These techniques promise a new era of Gigantic MIMO—tailored for real-world deployments and intelligently optimised for massive spatial multiplexing without requiring an abundance of antennas.

This keynote examines the architectural transition from deterministic 5G design to AI-native 6G, where intelligence is embedded across device, RAN, core, operations, and lifecycle layers to meet extreme targets in throughput, latency, positioning, and energy efficiency. Rather than treating AI as an external optimisation layer, the talk presents 6G as a distributed and federated system in which learned policies reshape core engineering, radio control, and spectrum management itself. The presentation then shows how this architectural shift brings together several structural enablers and consequences: network slicing and policy control in the core, AI-assisted beamforming in the RAN, RIS and NTN as programmable extensions of wireless coverage, ISAC as a sensing-capable infrastructure layer, and ONNX/Open RAN style interoperability as part of deployable openness. It also addresses the associated constraints, including inference-driven energy costs, the need for explainable AI and auditability, outcome-based licensing for dynamic spectrum access, and the operational challenge of post-quantum security at telecom scale. The keynote argues that 6G should be understood not as a faster air interface, but as an integrated, programmable, and governable cyber-physical network system whose value and risk emerge from the interaction of its components.

Poster Display Day is an annual event of the Department of Electrical and Computer Engineering (HKU-ECE), showcasing the culmination of students’ Senior Design Projects. The event highlights students’ dedication and innovation in applying the engineering knowledge and skills they have developed throughout their studies to real-world technical challenges. Beyond technical excellence, the projects also foster self-awareness, self-management, and the ability to explore and extend students’ personal capabilities. 💪✨

This year’s event was successfully held on April 21, 2026, at the Rayson Huang Theatre, The University of Hong Kong. During the ceremony, the Best Poster Award and Outstanding Poster Award were presented to sixteen students who achieved the highest marks for their outstanding poster presentations, as evaluated by judges. Among all participants, three students who attained the highest overall scores were honoured with the Best Poster Award in recognition of their exceptional performance. We were honoured to have Prof. Wei-Ning LEE, Associate Head of the Department, present the awards to the recipients.

The event concluded with warm closing remarks by Prof. Leo Tianshuo ZHAO, Senior Design Project Coordinator, who expressed his sincere appreciation to all undergraduate students, guests, and colleagues for their contributions to the event’s success. We look forward with great anticipation to the continued achievements and future endeavours of our students.

Congratulations to the award recipients! 👏
