Research

Antennas and signal processing

These activities relate to the development of RF components and sub-systems and their related baseband techniques, particularly considering the new frequencies being adopted for 5G+ and 6G, such as direct satellite-to-user through beamforming, reflecting intelligent surfaces, and THz sensing. We also work on characterisation and control of the radio environment.

Artificial intelligence for wireless communications

In this research we investigate how to apply the rapidly burgeoning field of artificial intelligence and deep learning to the problems of radio communications links in beyond 5G or 6G mobile networks in order to improve their performance and adaptability.

Intelligent and high-performance networking and service delivery

This research covers the topics of future networking, network management and service delivery technologies in 5G, 5G+ and 6G. These include the development of high performance and flexible networking mechanisms, techniques and protocols, artificial intelligence (AI) driven network and service management, network support for emerging multimedia, extended reality, 'internet of things' and time-synchronous applications with quality of service and quality of experience assurances.

MAC, RRM and RAN management

The aim of this research is to optimise the use of resources within a resource limited network and to orchestrate resources from different networks while satisfying the quality of experience requirements of each user. We also apply advanced technologies such as ambient sensing and Artificial Intelligence to manage the complexity of future radio access networks such as 5G+ and 6G.

Mobile network security

The scope of this research covers security and privacy for 5G+ and 6G services that is aided by next generation AI and a network of networks comprising short range, wide area and satellite networks, including major verticals such as vehicle and transport communications (V2X) and 5G/6G-based 'internet of things'. The work covers scalable and light weight authentication and access control and uses techniques such as blockchain technology and quantum safe cryptography.

New physical layer

The main objective of this research is air interface design for future wireless networks (primarily 5G+ and 6G) with the focus on ubiquitous coverage, massive connectivity, exceptionally low latencies, ultra-fast data transmissions, geolocation and sensing, uniform user experience, green energy and sustainability as well as underpinning service multiplexing, mixed unicast/multicast/broadcast, and high mobility communications.
