Annex 1 A.5 justification for the reference to ETSI TS 123 401 V15.8.0 (2019-10)

Section 1 Introduction

According to ITU procedures, as described in ITU-T Recommendation A.5, any normative reference to documentation produced outside the ITU (other than ISO and IEC texts) needs to be evaluated by the study group or working party before a decision is made to incorporate the reference in an ITU-T Recommendation.

This TD contains the A.5 justification information for new Recommendation ITU-T X.1364 (ex X.nb-iot) as published in SG17-R45.

Section 2 Referred documents and respective justifications

  • ETSI TS 123 401 V15.8.0 (2019-10), LTE; General Packet Radio Service (GPRS) enhancements for Evolved Universal Terrestrial Radio Access Network (E-UTRAN) access (3GPP TS 23.401 version 15.8.0 Release 15)
    • Normative.
    • The referenced document is the text on which Recommendation X.nb-iot is based.
    • Complete A.5 justification information can be found in Annex 1.
