DRIFT: Joint Channel Estimation and Prediction Towards Pilotless 6G Non-Terrestrial Networks
arXiv:2605.31065v1 Announce Type: cross Abstract: Non-terrestrial networks (NTNs) are expected to play a pivotal role in sixth-generation (6G) systems by enabling ubiquitous connectivity and massive communication. In this context, channel prediction emerges as a key technique to improve the spectrum utilization efficiency by limiting the pilot overhead. However, many proposed predictors based on artificial intelligence (AI) are characterized by high inference complexity, posing challenges to onboard implementation. In this paper, we address the challenge of designing accurate yet computational
The push for 6G systems and the crucial role of non-terrestrial networks (NTNs) in providing ubiquitous connectivity are accelerating research into efficient channel estimation and prediction. The existing AI models, while accurate, pose significant challenges for onboard implementation due to their high inference complexity.
This research addresses a critical technical hurdle for 6G NTNs by proposing a method that balances accuracy with computational efficiency for channel estimation and prediction, directly impacting the viability and performance of future global communication networks. Improved spectrum utilization through pilotless operation will allow for greater network capacity and lower operational costs.
The development of computationally efficient AI-driven channel prediction methods will enable 'pilotless' 6G NTNs, significantly reducing overhead and improving spectral efficiency in satellite and aerial communication. This will make widespread and robust global connectivity more feasible and cost-effective.
