6.2 THE 3GPP ROLE<br />
Figure 6.1. Progression towards IMT-Advanced. 110<br />
3GPP technologies have been an essential and widely deployed part of the 3G technology family under<br />
the ITU-R IMT-2000 family since the onset of these recommendations 111 released by the ITU-R. 3GPP<br />
has continued its role of enhancing its members of the IMT-2000 family through all released revisions of<br />
Recommendation ITU-R M.1457 and has continued this evolution of 3G through the incorporation of LTE<br />
technology in the ITU-R work.<br />
3GPP plays an important role in IMT-Advanced and has had a program underway for developing<br />
technology solutions for IMT-Advanced beginning with 3GPP workshops on the “Systems Beyond IMT-<br />
2000.”<br />
The purpose of these workshops was to contribute to the international understanding of IMT-Advanced,<br />
and to further the development of LTE-Advanced. The first 3GPP workshop was held on November 26,<br />
2007, as an informational and educational session to provide relevant information related to IMT-<br />
Advanced in the ITU-R. A more detailed second workshop on IMT-Advanced and LTE-Advanced was<br />
held on April 7-8, 2008, attended by over 160 international participants and addressed 58 documents.<br />
During this workshop, operators’ and manufacturers’ views on possible requirements for LTE-Advanced<br />
as well as ideas and proposals for LTE-Advanced were exchanged and discussed. On May 27, 2008,<br />
3GPP held a third workshop to focus specifically on the 3GPP requirements for LTE-Advanced.<br />
3GPP continued with its working assumption that the 3GPP proposal for IMT-Advanced should be based<br />
on E-UTRAN capabilities and the requirements for IMT-Advanced in ITU-R should initially be not less<br />
than those contained in 3GPP TR 25.913. 112<br />
Furthermore, 3GPP set an objective to establish (in Study and Work Items) requirements and capabilities<br />
higher than those contained in TR 25.913 towards meeting ITU-R requirements for IMT-Advanced.<br />
