New physical layer
The main objective in this area is an air interface design for dense small cells with the focus on higher spectral efficiency, reduced latency, relaxed synchronisation requirements, flexibility in spectrum aggregation and bandwidth and higher energy efficiency.
The main objective in this area is an air interface design for 5G wireless networks with the focus on higher spectral efficiency, reduced latency, relaxed synchronisation requirements, flexibility in spectrum aggregation and bandwidth and higher energy efficiency.
We address topics such as new wave forms (including non-orthogonal and enhanced orthogonal waveforms), Massive MIMO, hybrid beamforming, non-orthogonal multiple access, non-coherent transmission techniques, mm-wave communications, satellite-terrestrial integration, joint DSP and RF design, converged unicast/multicast/broadcast solutions as well as RAN slicing.
We design the air interface to support a wide range of 5G vertical application domains with vastly diverse technical requirements, such as media and entertainment, factories of the future, energy, eHealth, automotive etc. We take a holistic approach to 5G physical layer design with focus on implications on the overall system performance rather than few dB gain on the link level.
We aim to provide a complete air interface solution for 5G (UL/DL, x-cast, mMTC, eMBB, URLLC) which will fulfil the following 5G PHY KPIs:
- High spectral and energy efficiencies
- Low control signalling overhead
- Low air-interface latency (propagation, transmission and processing delay)
- No stringent time-frequency synchronisation requirements
- Facilitate carrier aggregation across highly fragmented spectrum including license-exempt band
- Scalable for MIMO systems
- Support for multi-services including device to device and machine type communications
- Support for massive connectivity and ultra-high connection density
- Achieve harmonised/unified air-interface across different networks.
