The objective is to design a new flexible and adaptive air interface for mobile networks of the 5th generation (5G). The new air interface is supposed to enable future 5G applications such as vehicular communication, massive machine communication and mission critical communication. A new design is needed to support a massive number of connected devices and to provide significant gains in spectral and energy efficiency while ensuring highly reliable links and low end-to-end latencies.
The project approach is based on a combination of various components that are developed in the project. These components include, among others, new waveform and frame designs, advanced and adaptive retransmission techniques, new coding strategies, new interference mitigation techniques for small cell deployments, and efficient massive access protocols. The exact combination of the components depends on the particular application.
HHI contributes to the development of several components including multi-cell interference management, advanced MIMO techniques for new waveforms, and efficient massive access methods. Furthermore, HHI participates in the demonstration activities.
