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.
We address topics such as:
- Integration of terrestrial and non-terrestrial (including satellite)
- Non-orthogonal multiple access/sparse code multiple access
- Cell-less massive multiple-input and multiple-output (MIMO)
- Reflecting intelligent surface (RIS, aka LIS)
- Non-coherent transmission techniques
- Full duplex radio
- mmWave and THz communications
- Physical layer security
- Joint digital signal processors and radio frequency design
- Converged unicast/multicast/broadcast solutions and integrated geolocation
- Sensing and communications
- RAN slicing design
To support a wide range of new services and applications that can be provided by future networks with vastly diverse technical requirements, such as immersive extended reality (XR), intelligent transport systems, holographic telepresence assisted e-health, telecare, beyond industry 4.0, etc. We take a holistic approach to 5G+ and 6G physical layer design with focus on implications on the overall system performance rather than a few dB gain on the link level.
We have developed 5G-compliant link-level and system level simulators in order to evaluate the performance of our innovative solutions in a practical and industrially relevant context defined by 3GPP and continue to evolve these towards the 6G era.
