New Waveforms for 6G Communications, Sensing, and Localization

Description: The advent of 6G technology demands revolutionary waveform designs to simultaneously address three critical imperatives: ultra-reliable communication, high-resolution sensing, and centimeter-level positioning. Unlike 5G’s focus on enhanced mobile broadband, 6G aims to unify these functionalities into a single framework, requiring waveforms with unprecedented spectral efficiency, adaptability, and multi-dimensional capabilities. A critical enabler of these advancements lies in the design of novel waveforms that go beyond traditional orthogonal frequency-division multiplexing (OFDM) to meet the diverse and demanding requirements of future networks.

The design of new waveforms is a cornerstone of 6G research, driven by the need to overcome fundamental limitations of current technologies and unlock transformative capabilities. Below, we highlight the critical motivations for prioritizing waveform innovation in 6G (1) Bridging the Gap Between 5G Limitations and 6G Ambitions: While 5G relies heavily on OFDM, its rigidity in handling high mobility, ultra-reliable low-latency communication (URLLC), and non-orthogonal resource allocation poses significant barriers to 6G’s vision. Emerging applications—such as extended reality (XR), autonomous systems, and tactile internet—demand waveforms that dynamically adapt to heterogeneous requirements. For instance, OTFS has shown promise in high-Doppler scenarios, while NOMA-based waveforms address spectrum scarcity. Without reimagining waveforms, 6G risks falling short of its performance targets. (2) The Rise of Integrated Sensing and Communication (ISAC): 6G aims to unify communication and sensing into a single infrastructure, enabling applications like environmental monitoring, gesture-based interfaces, and collision avoidance. Traditional waveforms, however, are optimized solely for data transmission. Novel ISAC-centric waveforms must balance tradeoffs between sensing resolution, communication throughput, and spectral efficiency. This integration is pivotal for reducing hardware costs, minimizing spectrum fragmentation, and enabling context-aware networks. (3) Spectrum Expansion into THz and mmWave Bands: The exploitation of THz frequencies (0.1–10 THz) is central to achieving 6G’s terabit-per-second data rates. However, these bands suffer from severe propagation losses and hardware imperfections. Waveform designs must compensate for these challenges through techniques like ultra-wideband modulation, advanced equalization, and intelligent beamforming. Simultaneously, mmWave bands require waveforms compatible with massive MIMO and reconfigurable intelligent surfaces (RIS), demanding innovations in spatial signal processing. (4) Sustainability and Energy Efficiency Imperatives:With global attention on reducing carbon footprints, 6G waveforms must prioritize energy efficiency. Low-PAPR waveforms, such as those based on constant envelope OFDM (CE-OFDM), minimize power amplifier inefficiencies, while SWIPT-compatible designs enable battery-free IoT devices. Energy-optimized waveforms are critical for sustainable scaling of 6G networks, particularly in energy-constrained environments like rural areas or space-terrestrial networks. (5) AI/ML: A Game-Changer for Adaptive Waveforms: The integration of AI/ML into waveform design marks a paradigm shift. Machine learning enables real-time optimization of waveform parameters in response to dynamic channel conditions, user density, and application requirements. For example, reinforcement learning can autonomously adjust modulation schemes or pilot spacing to maximize throughput in congested networks. Such adaptability is essential for 6G’s vision of self-optimizing, context-aware networks. (6) Global Research Momentum and Industry Alignment : Leading institutions (e.g., MIT, Fraunhofer HHI), industry consortia (e.g., Next G Alliance, Hexa-X), and standardization bodies are actively prioritizing waveform research. Recent breakthroughs—such as OTFS field trials and AI-driven waveform prototypes—underscore the feasibility of radical innovations. This workshop aligns with global efforts to establish a unified roadmap for 6G waveforms, fostering collaboration between academia, industry, and regulators.

This special session provides a timely platform to address the multifaceted challenges of 6G waveform design. By uniting researchers across disciplines—signal processing, AI, hardware engineering, and standardization—we aim to accelerate the development of waveforms that redefine the boundaries of wireless technology. Contributions to this workshop will directly shape the 6G ecosystem, ensuring it meets the demands of a hyper-connected, intelligent, and sustainable future. We invite contributions on theoretical innovations such as channel estimation, sensing and localization algorithms, novel detection schemes, and scalable multi-antenna or multi-user architectures, as well as practical implementations including hardware prototyping, standardization pathways, and industry trials. By fostering dialogue between academia and industry, this forum targets accelerating the development of next-generation waveforms tailored to 6G’s transformative vision.
