Introduction
￭ Standardisation work needed to include ER-GSM band into relevant Standards
￭ ETSI TC RT activities  closed
￭ 3GPP GERAN activities  almost closed (*)
￭ ETSI MSG activities  pending

3GPP GERAN activities 1/3
￭ During 3GPP GERAN #59 several Change Requests were approved
￭ CR to TS 45.001 - High level description of frequency band and RF channels
￭ CR to TS 45.005 - Description of the RF parameters to be used over the new 3 MHz
￭ CR to TS 45.008 - Corrections needed with the use of ER-GSM 900 term in TS 45.005
￭ CR to TR 45.050 - Summary of the coexistence studies captured in this report
￭ CR to TS 24.008 - New indicator in the Classmark 3 for ER-GSM MS signalling
￭ Compromise found between public and railway operators
￭ Conditions to use ER-GSM spectrum in case of uncoordinated deployment of new ER-GSM equipment close to a
legacy equipment already deployed in E-GSM band described in TS 45.005 (see next slide)
￭ In case of coordinated deployment higher output power can be allowed
ER-GSM standardisation major milestone accomplished with the compromise found at GERAN level

3GPP GERAN activities 3/3
￭ All "Core Specifications" finalized, Test Specifications remaining
￭ CR to TS 51.010 - Test Cases for ER-GSM mobiles
￭ CR to TS 51.021 - Test Cases for ER-GSM base stations
￭ Test Specifications important for Harmonized Standards
￭ Test Cases are needed in EN 301 502 and 301 511 to demonstrate compliance of equipment covering the
essential requirements of article 3.2 of the R&TTE Directive
￭ ETSI Technical Committee in charge of those EN is MSG

CEPT/ECC discussions
￭ 3GPP GERAN liaised about ER-GSM CRs approval (Aug. 2013)
￭ 3GPP RAN4 and ETSI TC MSG for the specification part
￭ ECC PT1 and ECC WG FM for the regulatory part
￭ ECC PT1 liaised back (Sept. 2013)
￭ Asking for clarifications about the working assumptions used to derive the ER-GSM RF parameters, in particular
￭ Attenuation slope 6 and 11 dB/MHz
￭ Minimum Coupling Loss between ER-GSM BS and UTRA/E-UTRA BS
￭ 3GPP GERAN provided answers (Nov. 2013)
￭ Feedback on working assumptions for attenuation slope and Minimum Coupling Loss

￭ 3GPP GERAN #61 meeting on 24-28 Frebruary in Sophia-Antipolis
￭ Presentation of Test Specifications Change Requests
￭ ETSI TC MSG #37 meeting on 05-07 March in France (TBD)
￭ Start of the EN update process?
