1、pted Recommendation ITU-R M.1645 on the Framework and overall objectives for the future development of IMT-2000 and IMT-Advanced systems. WRC-07 Agenda item 1.4 has “to consider frequency-related matters for the future development of IMT-2000 and systems beyond IMT-2000 taking into account of the results of ITU-R studies in accordance with Resolution 228 (Rev.WRC-03)”. Report ITU-R M.2078 provides the estimated spectrum bandwidth requirement for pre-IMT-2000, IMT-2000 and IMT-Advanced for the ye。

2、 ITU-R 79/4) ( 1994) The ITU Radiocommunication Assembly, considering a) that the World Administrative Radio Conference for Dealing with Frequency Allocations in Certain Parts of the Spectrum (Malaga-Torremolinos, 1992) (WARC-92) allocated the frequency band 13.75-14 GHz to the fixed-satellite service (FSS) on a primary basis; b) c) radiolocation and radionavigation services in order to allow these services to share this band; d) the values given in RR No. 855A and report its outcome; e) f) g) t。

3、he role of the Radiocommunication Sector is to ensure the rational, equitable, efficient and economical use of the radio-frequency spectrum by all radiocommunication services, including satellite services, and carry out studies without limit of frequency range on the basis of which Recommendations are adopted. The regulatory and policy functions of the Radiocommunication Sector are performed by World and Regional Radiocommunication Conferences and Radiocommunication Assemblies supported by Study。
