🎉 Thrilled to share that our paper “Enabling Scalable Distributed Beamforming via Networked LEO Satellites Towards 6G” has been accepted for publication in IEEE Transactions on Wireless Communications!

🛰️ As single-satellite links face fundamental limits in link budget and array aperture, this work demonstrates how coordinated multi-LEO beamforming can unlock massive gains in throughput and coverage for future 6G non-terrestrial networks. We propose scalable distributed beamforming frameworks that rely solely on statistical CSI and exploit inter-satellite links (ISLs) for cooperative optimization across satellites.

💡 Highlights:
⭐ Statistical-CSI-based design: Derived a closed-form ergodic sum-rate lower bound and formulated a power-constrained beamforming optimization problem without requiring instantaneous CSI, which is hardly available in LEO scenarios.
⭐ Distributed optimization via ISLs: Proposed two distributed WMMSE-based algorithms over Ring and Star ISL topologies, achieving near-centralized performance with vastly improved scalability.
⭐ System-level insights: Demonstrated through simulations the delay–overhead tradeoff.
