Resolution ITU-R 57-1
Principles for the process of development of IMT‑Advanced • Deliverables: develop Recommendations and Reports for IMT, including Recommendation(s) for radio interface specifications
• Timeframe: it shall be an on-going and timely process with defined outputs that take into account developments external to ITU‑R
• Participation: that radio interface technologies (RITs) shall be developed based on submissions from ITU-R Membership, and may additionally be based on submissions invited from external organizations
• Equitability: the process shall give equal opportunity to all proposed technologies to be evaluated against the requirements for IMT
• Maintenance: that new radio interfaces that are developed over time should be considered for inclusion in IMT in a timely fashion

IMT Specifications q In 13th revision of M.1457 (IMT-2000) q In 2ns revision of M.2012 (IMT-Advanced)
• 9 transposing organizations : IEEE, ITRI, TTA, ARIB, WiMAX Forum, ETSI, ATIS, CCSA
q GCS (Global Core Specification) Proponent:one of the RIT/SRIT Proponents for the relevant technology (e.g., 3GPP and IEEE 802)
q A Transposing Organization must have been authorized by the relevant GCS Proponent to produce transposed standards for a particular technology, and must have the relevant legal usage rights. (e.g., ETSI, ATIS, TTA, ARIB, CCSA)
q IMT-2000 and IMT-Advanced transposing organizations are required to send updates to ITU-R for the ITU-R M.1457 and M.2012 documents
