Abstract:
The research of 6G technologies has attracted significant attention recently. Particularly, 6G wireless networks aim to support a myriad of new applications, such as metaverse, digital twins, autonomous driving, etc., raising much higher requirements on different performance/functional indicators like data rate, spectrum/energy efficiency, mobility, and accurate sensing capability. These can be rather challenging to achieve by classical microwave frequencies and waveforms in existing 4G/5G networks. Specifically, the microwave spectrum cannot support the Tbps data transmission due to bandwidth shortage, which necessitates the exploitation of THz frequencies and above. Traditional waveforms (e.g., OFDM/SC-FDE) are not that suitable for THz communications under severe fading and path loss, motivating new waveform design resilient to harsh channel conditions. Moreover, to satisfy the other dimensions of the 6G requirements, artificial intelligence/large language model (AI/LLM) empowered waveform design, novel spectrum/energy efficient modulation, robust waveform against Doppler shifts under high mobility and ISAC waveform design that reaches a good performance balance between communication and sensing, are considered to be significant topics within 6G. These emerging waveform-related topics have started to draw attention from the global researchers and to our best knowledge, the majority of relevant studies with 6G are still in their infancy. Against this background, it is the right time to motivate interesting philosophies around the next-evolution waveform (NEW) design for the incoming 6G network with our proposed workshop, which is believed to accelerate the development of 6G regarding communication theory, applications and standardization from physical-layer perspective. Specifically, this workshop will focus on cutting-edge waveform-related technologies considered as potential candidates for 6G networks with unprecedented data rate, energy efficiency, mobility, and sensing accuracy requirements. Topics of interest include, but are not limited to:
- Emerging waveform-related design resilient to doubly dispersive channels (e.g., OTFS, OCDM, AFDM)
- New waveform design for mmWave/THz/optical wireless communications
- Novel spectrum/energy efficient modulation for 6G (e.g., backscatter communications, zero-power communications)
- Innovative OFDM-related techniques and alternative waveforms
- AI/LLM-based waveform optimization for 6G
- Waveform/modulation for nano-scale communications (e.g., molecular communications)
- Waveform-related design under quantum communication architectures (e.g., Rydberg atomic receiving)
- Advanced ISAC waveform design for 6G
- Waveform design regarding physical-layer security within 6G
- Theoretical analysis for next-evolution communication/sensing waveform
- Low-complexity transceiver design for new waveforms towards 6G
