Summary

• What is new: Introducing the D-STAR concept for 360-degree full-plane service coverage and DBAP optimization scheme.
• Why this is important: Improving network coverage and reducing interference in both the primary and secondary regions for uplink and downlink users.
• What the research proposes: A dual STAR-RIS architecture (D-STAR) with a new DBAP optimization scheme for better interference management and signal optimization.
• Results: The D-STAR architecture with the DBAP optimization outperforms conventional RIS, STAR-RIS, and half-duplex networks in simulation tests.
