The past few months have witnessed a number of specrum-related events and announcements that should be of interest to academic researchers working in the field of spectrum technology and policy and guide future research efforts in this field. The December 2023 column [1] went to press just as The National Telecommunications and Information Administration (NTIA) in the U.S. released its National Spectrum Strategy (NSS) on November 13, 2023 [2], where the bands 3.1–3.45 GHz, 5.03–5.091 GHz, 7.125–8.4 GHz, 18.1–18.6 GHz and 37.0–37.6 GHz were identified for study over the next 2 years for possible allocations to commercial wireless services. Shortly following this release, the International Telecommunications Union (ITU) held the World Radiocommunications Conference 2023, WRC-23, during November 20 - December 15, 2023 in Dubai [3]. The February 2024 column [4] reported on some of the outcomes of WRC-23, specifically a number of study items that will be pursued by the ITU-R, the Radiocommunication Sector of the ITU, to be completed in time for WRC-27, and encouraged researchers to contribute to this effort. Most recently, the NTIA released the NSS Implementation Plan (IP) on March 12, 2024 [5], detailing a process and timeline for executing the strategy laid out in the NSS. This column will describe the main aspects of the NSS and the IP that will be of interest to researchers in the field.

国家频谱战略和实施计划

过去几个月发生了许多与频谱相关的事件和公告，这些事件和公告应该引起频谱技术和政策领域的学术研究人员的兴趣，并指导该领域未来的研究工作。 2023 年 12 月专栏 [1] 付印之际，美国国家电信和信息管理局 (NTIA) 于 2023 年 11 月 13 日发布了国家频谱战略 (NSS) [2]，其中频段 3.1–3.45 GHz、5.03 –5.091 GHz、7.125–8.4 GHz、18.1–18.6 GHz 和 37.0–37.6 GHz 已确定在未来 2 年内进行研究，以便可能分配给商业无线服务。此版本发布后不久，国际电信联盟 (ITU) 于 2023 年 11 月 20 日至 12 月 15 日在迪拜举行了 2023 年世界无线电通信大会 (WRC-23) [3]。 2024 年 2 月专栏 [4] 报道了 WRC-23 的一些成果，特别是国际电联无线电通信部门 ITU-R 将开展的一些研究项目，将在 WRC-27 之前及时完成，并鼓励研究人员为此做出贡献。最近，NTIA 于 2024 年 3 月 12 日发布了 NSS 实施计划 (IP) [5]，详细说明了执行 NSS 中规定的战略的流程和时间表。本专栏将描述该领域研究人员感兴趣的 NSS 和 IP 的主要方面。
