MWC：蘋果領跑6G而非追隨

🔑 增強重點摘要

• •Ericsson's demo with MediaTek features a conducted data call on 6G centimeter-wave spectrum using prototype RAN and UE systems up to the IP layer[1][2].
• •MediaTek demo highlights contention-based buffer status reporting, a new 6G feature that reduces latency at scale for AI-enhanced XR applications[1][2].
• •MRSS demo employs two proof-of-concept systems—one real 5G and one simulated 6G—connected to an Ericsson TDD mid-band base station for real-time validation[1][2][3].

🛠️ 技術深入

• •Multi-RAT Spectrum Sharing (MRSS) enables simultaneous 5G and 6G operation in shared frequency bands, reducing resource waste and signaling overhead during migration[1][2][3][4].
• •Apple-Ericsson demo uses TDD mid-band base station with separate 5G PoC system and simulated 6G system to test interoperability and performance[1][2][5].
• •MediaTek-Ericsson prototype integrates RAN with UE comprising radios and baseband processing up to IP layer, demonstrating cm-wave data call and contention-based buffer status reporting for low-latency URLLC[1][2].
