行动通讯新频率：6G的准备工作以及WRC-23开始前的情况

概述

2023 年世界无线电通讯大会 (WRC-23) 将于 2023 年 11 月在杜拜举行，是一次重点关注频率分配和有效频谱管理的重要国际会议。

本报告概述了 WRC-23 上围绕国际行动电信 (IMT) 的关键问题和争论，并强调了频率分配对行动技术的重要性。 此外，我们正在考虑 5G 和新兴 6G 网路的频率要求。 特别是，它强调增加中频频段、匹配频段的需要，并解决与频率分配相关的地缘政治问题。

主要问题：

• WRC-23 上与 IM 相关的主要问题和讨论有哪些？
• 满足先进 5G 和 6G 网路日益增长的需求的预期频率要求是多少？
• WRC-23 考虑辨识和分配的主要频段有哪些？ 另外，它的特征、潜在的好处和挑战是什么？
• 过去的会议（例如 WRC-19）的结果如何影响各国政府随后的频率分配？

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?
