Resolution GSC-13/01 on IMT standardization (1) Continuing Cooperation on IMT Standardization Recognizing: that Resolution ITU-R 56 describes a naming scheme for International Mobile Telecommunications whereby “IMT-Advanced” applies to those systems, system components, and related aspects that include new radio interface(s) that support the new capabilities of systems beyond IMT-2000; that ITU-R Study Group 5 and ITU-T Study Group 19 are continuing studies on IMT (encompassing both IMT-2000 and IMT-Advanced); that ITU-R Study Group 5 has initiated a process for the development of terrestrial radio interface technologies that will meet the technical and operational requirements of IMT-Advanced; that core network(s) are increasingly becoming access technology agnostic; that IMT and other rapidly emerging wireless broadband access technologies will make high-speed wireless access services available where this was not previously possible, thereby enabling access to advanced telecommunication, computing and entertainment services and capabilities, not only for urban but also for rural and other low density environments; that WRC-07 identified some additional spectrum for the implementation of IMT systems; that work on evolution of the radio technologies may converge to use similar techniques; and that there are related international, regional and national research activities in this area. Geneva, 13-16 July 2009

Resolution GSC-13/01 on IMT standardization (2) Continuing Cooperation on IMT Standardization Resolves: to encourage 3GPP, 3GPP2, IEEE, Participating Standards Organizations (PSOs) and others to continue to work on enhancing the IMT standards as an essential part of future telecommunication, computing and entertainment standards; to encourage the harmonization of candidate proposals for the radio transmission technologies for IMT and related networking standards; to invite 3GPP, 3GPP2, PSOs and others to take care of the evolution of the current systems and the long-term evolution for such systems taking into account copyrights, working procedures, IPR aspects etc. and report to the next meeting for review; to exchange information and views on candidate radio interface technologies for IMT-Advanced among PSOs allowing for efficient, effective and timely development of the IMT-Advanced standard; to encourage the Task Force under the GRSC to actively help in the exchange of information and views mentioned in 4), with the goal of consensus building; and to review this Resolution at future GSC meetings as required.
