DETAILED WORKING MECHANISM ON DEVELOPING ITU-R RECS. M.1457 / M.2012 (IMT RADIO INTERFACE RECOMMENDATIONS) Yoshinori ISHIKAWA, Hitachi, Ltd. GSC-18 Meeting, July 2014, Sophia Antipolis, France Document No: GSC-18_006 Source: Invited Speaker, ITU-R WP5D / ARIB Contact: Yoshinori ISHIKAWA Agenda Item: 5.1

Current Structure of Recs. M.1247 /M.2012 GSC-18, July 2014, Sophia Antipolis2 Recs. M.1457 / M.2012 contains hyperlinks of SDOs’ standards as: TS Evolved Universal Terrestrial Radio Access (E-UTRA); Physical channels and modulation This document describes the physical channels and modulation for E-UTRA.

Detailed mechanism GSC-18, July 2014, Sophia Antipolis3 Key concepts of this mechanism are: GCS (Global Core Specification) : - “GCS” is the set of specifications that defines a single RIT, ans set of RIT, or a RIT within an SRIT GCS Proponent (Represent an industry, organization, etc.) : - Single entity or collective entity that provides a GCS as included in Recommendations - have legal authority to grant to ITU the legal usage rights Transposing Organizations : - Authorized by the GCS Proponents to produce transposed standards with legal authority to grant to ITU the legal usage rights

Typical procedure for updating recommendation 4 ITU-R GCS Proponent / Transposing Organizations (T.O) Send liaison to GCS Proponents announcing update schedule Request for providing update information Answer whether they are willing to update Radio Interface Review the updated RITs and capabilities Assess the evaluation results of updated RITs Revise Rec. based on GCS Proponents proposal Request T.O to provides hyperlinks Inform abstracts of updated RIT Meeting Y Meeting Y+1 Meeting Y-1 Provides Updated GCS Proposed texts of Rec. T.O. List Self-evaluation Meeting Y+2A / 2B Transpose GCS to its Standards Provides hyperlinks Finalize Recommendation with T.O’s hyperlink

Typical procedure for updating recommendation GCS Proponents & Transposing Organizations of current IMT-Advanced RITs LTE-Advanced GCS Proponent: 3GPP OPs (ARIB, ATIS, CCSA, ETSI, TTA & TTC) Transposing Organizations: ARIB, ATIS, CCSA, ETSI, TTA & TTC WirelessMAN-Advanced GCS Proponent: IEEE Transposing Organizations: ARIB, IEEE, ITRI, TTA & WiMAX Forum GSC-18, July 2014, Sophia Antipolis

Merits of this Mechanism GSC-18, July 2014, Sophia Antipolis6 Results from above mechanisms: Typically 5 ITU-R WP 5D meetings are required for updating Recommendation. (2 year cycles) It is a almost same duration for GCS Proponents to update their GCS Smooth introduction to the market -> GCSs are quickly transposed into National / Regional Standards and readers of the recommendation can easily find those Similar Recommendation structure is also employed in Rec. ITU-R M.1801 (BWA Radio Interface Recommendation) Recs. ITU-T Q.1741/1742 (IMT-2000 Core NW Recommendations)
