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
