Wireless connectivity solutions and RAN technologies

Enormous data rates and increasing requirements for reliability and lower latencies require different 5G/6G radio access network (RAN) solutions, which need to be optimized for a wider range of frequency bands and operator models to serve the future vertical applications. Dense deployments of small cells with virtualized network resources, and increasing edge computing capabilities change the mobile network architecture and promote the establishment of location specific 5G/6G networks. 

The challenge is to develop new wireless connectivity solutions and RAN design principles, where the trade-offs between network density, capacity, latency and other competing metrics such as energy efficiency, and implementation cost are well understood as a function of frequency, bandwidth and user mobility.

Our goal in 6Genesis research is to develop novel wireless connectivity solutions and RAN technologies for 5G/6G networks that allow ultra-reliable, low latency and secure service delivery including advanced physical layer technologies (PHY) and new dynamic and virtualized networking technologies. We investigate how the increasing carrier frequency and system bandwidth together with increasing heterogeneity of the required services will impact overall radio access network design. Network capacity will be enhanced by the introduction of radio spectrum at mm-wave and THz bands for which we will develop new wireless connectivity and RAN design and optimization solutions.


Our practical design solutions will include advanced PHY technologies where novel 5G/6G waveforms, air interfaces, transceiver algorithms and channel models are developed. Examples of these include interference coordination/mitigation mechanisms with different types of multiple-input, multiple-output (MIMO) multi-antenna transceiver technologies as well as communications concept with embedded positioning to solve the lack of accurate indoor positioning.

We will also develop new dynamic networking technologies, where software-defined networking (SDN), network function virtualization (NFV) and network slicing are used to provide an agile and dynamic networking platform for supporting multiple virtual networks on demand on top of a common shared physical infrastructure. The developed PHY and networking technologies will be developed by considering the security requirements and related security mechanisms will be designed.
