Oct 7–30, 2026, ITU Radiocommunication Sector Study Group 4 (SG4) and working
parties WP4A, WP4B and WP4C met in Geneva for the sixth WRC‑27 study‑cycle
session. The Chinese delegation participated in review of the draft Conference
Preparatory Meeting (CPM) report, focusing on market‑relevant items: proposed
direct‑to‑handset/mobile frequency allocations, restrictions on transmissions
from unauthorized earth stations, and potential optimizations to Radio
Regulations Article 4.4. Delegates also debated satellite‑mobile protection
criteria, IMT‑2030 satellite air‑interface performance, standards for network
monitoring and control centers, Article 22 limit issues, and drafted/revised
proposals and study reports for satellite fixed and broadcast services.
