行動通訊新頻率：6G的準備工作以及WRC-23開始前的情況

概述

2023 年世界無線電通訊大會 (WRC-23) 將於 2023 年 11 月在杜拜舉行，是一次重點關注頻率分配和有效頻譜管理的重要國際會議。

本報告概述了 WRC-23 上圍繞國際行動電信 (IMT) 的關鍵問題和爭論，並強調了頻率分配對行動技術的重要性。 此外，我們正在考慮 5G 和新興 6G 網路的頻率要求。 特別是，它強調增加中頻頻段、匹配頻段的需要，並解決與頻率分配相關的地緣政治問題。

主要問題：

• WRC-23 上與 IM 相關的主要問題和討論有哪些？
• 滿足先進 5G 和 6G 網路日益增長的需求的預期頻率要求是多少？
• WRC-23 考慮辨識和分配的主要頻段有哪些？ 另外，它的特徵、潛在的好處和挑戰是什麼？
• 過去的會議（例如 WRC-19）的結果如何影響各國政府隨後的頻率分配？

Summary

The World Radiocommunication Conference 2023 (WRC-23), to be held in Dubai in November 2023, represents a pivotal international event focused on the allocation of frequencies and effective spectrum management.

This report helps to outline the key issues and discussions surrounding International Mobile Telecommunications (IMT) at WRC-23. It also highlights the importance of spectrum allocation for mobile technologies. In addition, the document examines spectrum requirements for 5G and emerging 6G networks. In particular, it highlights the need for additional mid-band spectrum, harmonised bands, and addresses the geopolitical dimensions associated with spectrum allocation.

Key questions:

• What are the key IM-related issues and discussions at WRC-23?
• What are the expected spectrum requirements to meet the growing demands of advanced 5G and 6G networks?
• What are the main frequency bands being considered for identification and allocation at WRC-23, and what are their characteristics and potential benefits and challenges?
• How have the results of previous conferences, such as WRC-19, impacted on spectrum allocation by national governments since then?
