From September 28 to October 8, 2026, Working Party 5D (WP5D), operating under the aegis of Study Group 5 (SG5) within the International Telecommunication Union Radiocommunication Sector (ITU-R), convened a pivotal meeting in Geneva, Switzerland. This gathering marked the ninth session of WP5D within the study cycle leading up to the 2027 World Radiocommunication Conference (WRC-27). WP5D plays a crucial role in conducting in-depth technical, operational, and spectrum studies pertaining to the terrestrial components of International Mobile Telecommunications (IMT) systems.

The meeting's agenda was packed with significant discussions. Foremost among them were deliberations on the allocation of new frequency bands for IMT and direct-to-mobile satellite services. These discussions are vital for ensuring the efficient and interference-free use of spectrum resources, which are becoming increasingly scarce with the proliferation of wireless technologies. Another key topic was the submission process and templates for 6G wireless technologies, reflecting the industry's forward-looking approach to next-generation communication standards.

Furthermore, the meeting provided a platform for reviewing draft reports emanating from preparatory meetings for WRC-27. These reports offer insights into the ongoing discussions and potential outcomes of the conference. Additionally, research findings on interference protection rules for IMT systems from direct-to-mobile satellite systems were scrutinized, highlighting the importance of maintaining the integrity of IMT services in the face of potential interference from satellite-based communications.

China's active involvement in the meeting was evident through the adoption of two CPM-related documents and five frequency compatibility and sharing research documents that it submitted. These contributions underscore China's commitment to advancing global telecommunications standards and its proactive role in shaping the future of wireless communications.

The meeting attracted over 50 representatives from 12 relevant organizations, who participated through a hybrid online-offline format. This approach facilitated broad participation and ensured that diverse perspectives were heard and considered. The Chinese delegation, comprising experts and stakeholders from the telecommunications sector, successfully completed its participation tasks, contributing valuable insights and expertise to the discussions.
