1Opening of the meeting
The WG SE Chairman, Mr Bruno Espinosa, opened the 58th WG SE meeting held in Cardiff, Wales, United Kingdom at the kind invitation of the OfcomUK.
Mr Steve Bondwelcomed the delegates in Cardiffand expressed, as former WGSE secretary and member, his pleasure to open this meeting on behalf of Ofcom. He also highlighted the importance recognised by his administration of the technical work performed by WGSE. He concluded by providing some information on the practical arrangements during the meeting.
The WG SE chairman thanked Mr Steve Bond and the Ofcom for the invitation and the kind welcome.
The meeting was attended by a total of 57 delegates from 25 Administrations, ECO, ETSI, EUMETNET, DIGITAL Europe, Cable Europe, MSUA and UIC (see Annex 02 for details).
Apologies for absence were received from Enrico Tosato (Italy).
2Adoption of the Agenda, Schedule of Work
The Agenda was adopted as contained in document SE(11)001rev3. A copy is attached as Annex 01.
The list of documents is attached in Annex 03.
3 Matters arising from meetings of:
3.1 ECC
The WG SE chairman introduced briefly the minutes of the 27th ECC meeting (document SE(11)009) and highlighted the following points:
General considerations on hosting and running of meetings: proposals to improve the efficiency of meetings and to save costs were introduced at the ECC Steering Group and discussed at the ECC. The WG SE chairman encouraged the WG and its project teams to consider some of these ideas, such as shortening the time devoted to the reporting from other meetings, to promote, when appropriate, the use of electronic facilities and to consider possible co-location of meetings between WG SE project teams and other groups. Regarding the approval of the meeting minutes, WG SE agreed to maintain the current arrangement, i.e. approval of the minutes during the physical meeting. The creation of ECC TG5 on the ECC structure was noted.
The various activities within ECC subordinate groups (SE43, WG RA and WG FM correspondence groups) on SDR/CR were noted.
The ECC agreed on the arrangements for the cooperation with R&TTE-CA and ADCO. This will be addressed further under agenda item 13.
The ECC sent a liaison statement to CENELEC on PLC standardisation. This will be addressed further under agenda item 15.
Regarding the WG SE activities on work item SE21_16 (compatibility between radars in the band 2700 - 2900 MHz and the mobile service in the band 2500 - 2690 MHz), WG SE was invited, in the light of a request made at the RSCOM for an early availability of the results on the impact from the mobile service into radars, to develop as soon as possible preliminary findings, in particular for this direction of interference. This is discussed further under section 7 (SE21) and a report on the progress on this item will be brought to the attention of the ECC.
Regarding the SE40 activities on the new work item SE40_18 (compatibility between CGC/MSS terminals in the band 1980 - 2010 MHz and ECN systems in adjacent bands), the ECC identified the need for liaison activities with ETSI TC SES.
3.2 ECC PT1
ECC PT1 held its 37th meeting in Vienna, Austria (11 – 13 January 2011).
The ECC PT1 progress report to ECC was presented in SE(11)026.
WG SE received various liaison statements from ECC PT1 on the following issues:
-Compatibility between MSS CGCs in the band 2483.5-2500 MHz and IMT above 2500 MHz (document SE(11)017 further discussed under section 9 on SE40),
-Compatibility between radars in 2700-2900 MHz and the mobile service in the band 2500-2690 MHz: document SE(11)022 proposes to add some information to the draft report developed by SE21 concerning characteristics of mobile systems. This would need to be further considered by SE21 noting that additional information will be provided to SE21 by PT1.
-Compatibility between MSS terminals transmitting to a satellite in the band 1980-2010 MHz and ECN in the adjacent band: document SE(11)021 contains information on scenarios and characteristics on ECN. This would be further considered within SE40.
-Broadband Wireless Systems at 2.3 GHz: document SE(11)023 includes a reference to ITU-R Report M.2039 regarding characteristics for 2.3 GHz BWS and provides for information the latest draft of a cross border Recommendation developed by PT1 covering FDD and TDD networks at 2500 – 2690 MHz. This will be further discussed by SE7.
WG SE considered the issue raised by ECC PT1 to the SRD-MG on a potential inconsistency between CEPT Report 41 and ERC Recommendation 70-03 regarding the guard bands at the 1785 MHz boundary between MFCN and radiomicrophones. Recommendation 70-03 does not identify any need for a guard band whilst CEPT Report 41, based on the findings from ERC Report 63 developed years ago within WG SE, stipulates that a guard band of 700 kHz is needed to protect the GSM 1800 MHz base station reception. It is expected that this matter will be discussed in the coming WG FM meeting together with a proposal to extend the use of the band 1785-1800 MHz by radio microphones to the band 1800-1805 MHz. WG SE has invited SE7 to consider the issue further if required by WG FM. It was pointed out that CEPT Report 30 developed by SE42 considered similar compatibility scenarios between MFCN and PMSE and may include relevant information.
WG SE noted the on-going activities of ECC PT1 in particular on the revision ofECC Decision (06)01, the draft new ECC Decision on3.4-3.8 GHz on harmonised frequency arrangements and on cross-border coordination.
3.3 WG FM
The minutes from the 70th WG FM meeting (20 – 24 September in Goteborg) were consideredfor information in document SE(11)010.
In particular, WG SE discussed one liaison statement from WGFM and one from FM48:
- SE(11)003 is a liaison statement dealing with the DECT item. This has been considered by SE7 and the outcome from SE7 is presented under section 5.
- SE(11)004 is a liaison statement from FM48 on Broadband Direct-Air-to-Ground Communications (DA2GC). An initial list of candidate bands is provided and further discussions are expected in FM48 and WG FM to prioritise these bands. WGSE discussed the appropriate working arrangement to provide the support to FM48 on sharing/compatibility studies.However, due to the large number of frequency bands currently under consideration within FM48, it was felt premature to identify at this stage the optimal working arrangement from WG SE side. A decision is intended to be made at the next WG SE meeting where a more concise list of bands is expected to have been identified by WG FM/FM48. If studies on specific frequency bands are requested by WG FM before the next WG SE, WG SE agreed that studies under the responsibility of WGSE could be initiated by correspondence under the coordination of the WG SE chairman. This was reflected in a liaison statement to WG FM and FM48 (see Annex 20).
3.4 WG RA
The 21st meeting of WG RA was held in Ljubljana from the 14th to the 17th of September 2010.
WGSE noted a liaison statement from WG RA (SE(11)007 rev1) on the review schedule of ECC Deliverables by WGRA and the reply from ECC/PT1 (SE(11)Info06). No action was required from WG SE side.
The WG SE chairman proposed to take the opportunity of the co-location of the WG RA meeting to improve the synergy between both WG, in particular in the field of cognitive radios and invited the WG SE members to attend the session organised on the 26th of January by WG RA on this issue where a presentation of SE43 activities on white spaces was performed by the SE43 chairman, Mr Alexandre Kholod.The presentations made at the WG RA workshop are available at (select ‘event’ then ‘CEPT workshops’).
3.5 CPG
There has been one CPG meeting in Berlin since the previous WGSE meeting. Steve Bond, CPG vice-chairman presented ashort oral report from the CPG activities.
The CPG process is moving on according to the agenda. It is now in quite an essential period with the CPM in February 2011 and the first batch of ECPs which will be approved at the next CPG meeting in June 2011. He highlighted that there are currently some agenda itemswhere there are still various alternative ECPs and that the involvement of a wider number of CEPT administrations would help to find a way forward in these areas. He concluded by thanking WG SE for the support on WRC-12 Agenda Items 1.18, 1.20 and 1.8 (see section 7 on SE21 for the latest developments within WG SE related to WRC-12 AI 1.8).
The WG SE chairman also drew the attention of the meeting to the first proposals which were submitted to CPG PTA on WRC-12 Agenda Item 8.2 which will develop the agenda for the subsequent WRC.
3.6 ETSI
3.6.1 Report of ETSI activities
The report on ETSI activities was provided in document SE(11)024rev1. The meeting noted the various informative documents available on System Reference Documents under development in ETSI:
- SE(11)Info 01 informing about two systems reference documents under development on SRD equipment for wireless factory/industrial applications;
- SE(11)Info 03 on the ETSI ERM approval of the SRDoc on radar sensors for non-automotive surveillance applications in 76 GHz to 77 GHz frequency range. This has already been taken on-board by SE24 in its corresponding activity;
- SE(11)Info 05 on Spectrum Requirements for Smart Metering.
WGSE received two liaison statements from ETSI TC ERM on the public consultation related to the revision of ERC Recommendation 74-01 and the draft ECC Report 159. They are addressed under section 4.
3.6.2Relationship between WGSE and ETSI activities
Mr Marc Le Devendec (ECO) introduced document SE(11)016. It includes an update and a new formatting - based on the guidance from the ECC-ETSI meeting - of the spreadsheet initiated at the 56th WG SE meeting providing the list of ETSI Harmonised Standards under development in relation to the ongoing ECC activities.
The WG SE Chairman thanked Marc Le Devendec and the ETSI LO, Michael Mahler for the large amount of work in developing the spreadsheet. He stated that the spreadsheet was now stable enough to be used by WGSE in two areas:
- WG SE members were invited to circulate this document across their organisation in order to improve the involvement of CEPT administrations in the development and approval process of the draft ETSI harmonised standards related to ECC activities;
- Project Team chairmen were invited to analyse the spreadsheet and submit to their project team the extracts containing ETSI draft harmonised standards relevant to the activities of their PT for further consideration. They were also invited to provide feedback to Marc Le Devendec in particular on draft ETSI harmonised standards developed in ETSI groups other than TC ERM and therefore not covered in the current spreadsheet, such as TC BRAN, TC RRS, TC SES and WG TM4.
The meeting was also informed about the outcome from the last ECC-ETSI cooperation meeting. where a revision of the document describing the cooperation process betweenECC and ETSI has been endorsed.
In accordance with this process, WGSE decided to address a liaison statement to ETSI TC ERM to inform hem on the draft ECC deliverables approved at this WG SE meeting for Public Consultation (Annex 24).
The spreadsheet providing the ETSI Harmonised Standards under development and the document describing the cooperation process between ECC and ETSI are available at
4.Documents for final approval after public consultation
The comments received during the consultation period of the documents sent by WG SE have been summarized in document SE(11)005Rev1.
The WGSE chairman invited the Administrations to give the good example by using the appropriate template(available on the consultation page at in order to support ECO and the Project Teams in processing the comments.
WG SE considered the received comments and the resulting proposals from the responsible Project Teams on:
1)Draft ECC Report 156 on Conditions for possible co-existence between HAPS gateway links and other services/systems in the 5850-7075 MHz band; (SE19)
SE 19, as the responsible PT for this draft Report, previously endorsed the comments made by the Russian Federation and WGSE subsequently approved the ECC Report 156 for publication on the ECO website as given in Annex 06.
2)Draft ECC/REC(11)01 on guidelines for block allocation for fixed wireless systems in the bands 24.5-26.5 GHz, 27.5-29.5 GHz and 31.8-33.4 GHz; (SE19)
SE 19, as the responsible PT, previously endorsed the editorial comments made by WGRA.
After discussion, WGSE agreed to replace in the title of the Recommendation the word “allocation” with “assignment”. With this minor change WGSE decided to approve ECC/REC(11)01 for publication on the ECO website as given in Annex 07.
As a consequence to the publication of the REC(11)01 and taking into account the agreement expressed by WG FM on this proposal, WGSE decided to withdraw ERC/REC/(00)05, ERC/REC/(01)03, ECC/REC/(04)06.
3)Draft ECC Report 157 on the impact of radar spurious emissions on other radiocommunication services/systems; (SE21)
Three responses were received during the public consultation on the draft ECC Report 157 from Germany, France and Ericsson. Most of these comments were endorsed by SE21 and incorporated in a revised version (Annex 1 to document SE(11)015) submitted to WG SE for final approval.
After consideration of the SE21 proposal with one editorial improvement in the conclusion, WGSE approved the ECC Report 157 for publication on the ECO website as given in Annex 08.
4)Draft revision ERC/REC 74-01 on unwanted emissions in the spurious domain. (SE21)
Four responses were received during the public consultation on the draft revision of ERC Recommendation 74-01 from Germany, Ericsson, WG RA and CML. These proposals were addressed by SE21 which developed an amended version of the draft revision ERC/REC 74-01 (Annex 2 to document SE(11)015).
WG SE received additional observations from ETSI TC ERM (document SE(11)028) on this work, which expressed the support for the latest SE21 proposal related to multicarrier amplifiers when used for PMR technologies in the annex 2 to the revised Recommendation resulting from the comment submitted by CML. WG SE also noted that TC TETRA WG4 are considering initiating a work item to produce specifications for multicarrier transmitters in TETRA.
After consideration of the latest version proposed by SE21 with additional editorial improvements in the annex 5, WGSE approved the revision of the ERC/REC 74-01 for publication on the ECO website as given in Annex 09.
5)Draft ECC Report 158 on the impact of 26 GHz SRR applications using ultra-wideband (UWB) technology on radio services; (SE24)
In the absence of any comment during the public consultation, WGSE approved the ECC Report 158 without modification for publication on the ECO website as given in Annex 10.
Sweden pointed out that this study for a possible transfer up in the band for SRR_24, taking into the decision by RSC, is now overruled.
6)Draft ECC Report 159 on technical and operational requirements for the possible operation of cognitive radio systems in the "white spaces" of the frequency band 470-790 MHz. (SE43).
Eighteen comments received during the public consultation on draft ECC Report 159 were considered and reflected as appropriate in the text of the report by SE43 (SE(11)06-Annex 2rev1). The views from SE43 on all the comments received were made available as document SE(11)06-Annex 1.
WGSE received also one liaison statement from ETSI TC ERM (SE(11)029) that informed about the current activities within the ETSI on Cognitive Radio Systems and also suggested to extend Chapter 11 of ECC Report 159 with an item dealing with protection of cable services. Taking into account the terms of reference of WGSE it was decided not to follow this suggestion but to raise the issue to the ECC for any necessary guidance and coordination/cooperation with the relevant groups, e.g. CENELEC and ETSI.
ECC Report 159 was thus adopted for publication on ECO website as given in Annex 11.
5.Report from Project Team SE7 (Compatibility and sharing issues of mobile systems (except IMT) operating below 3 GHz
Mr Petteri Jokela, SE7 Chairman, introduced the SE7 progress report available in document SE(11)008Rev1. Since the last WG SE meeting, the PT SE7 has held two meetings: 6 - 8 October 2010 in Helsinki, hosted by Ficora, and 8-10 December 2010 in Copenhagen, hosted by ECO.
5.1 GSM for railway purposes (GSM-R)
SE7 has completed the draft ECC Report on the practical mechanism to improve the compatibility between GSM-R and public networks and to give guidance on practical coordination. SE7 has taken into account existing studies in ECC Report 96, ECC Report 146 and CEPT Report 41 dealing with compatibility between GSM-R and public mobile radio systems in the adjacent band. SE7 has also performed additional studies for the scenarios not covered by those Reports.
The draft Report identifies different mitigation measures to improve the compatibility between GSM-R and public networks. Some of the measures are applicable to only GSM-R, only to public networks, or to both. Their benefits and drawbacks are discussed. Some of the measures could be implemented in a short-term, while others may be only mid-term or long-term solutions.
A discussion took place on the receiver characteristics of GSM-R cab radio when facing interferences from adjacent wideband systems (see section 6 of the draft ECC Report). Comments were invited on this issue during the public consultation to check these characteristics.
WGSE considered this draft ECC Report on practical mechanisms to improve the compatibility between GSM-R and public mobile networks and guidance on practical coordination (SE(11)008 annex1) and approved it as draft ECC Report 162for Public consultation with minor editorial modifications. It is available as Annex 12.
A liaison statement to WGFM was developed to inform about the above (Annex 19).
5.2 Broadband Wireless Systems (BWS) at 2300-2400 MHz
SE7 has started its work on compatibility between BWS and existing services in the band 2300 – 2400 MHz and in adjacent bands and to develop appropriate measures to assist administrations in border coordination. The working document was considered for information SE(11)008-Annex 2). It includes currently characteristics of LTE-TDD systems and mobile WiMAX systems. Initial studies are carried out between LTE-TDD and space systems below 2300 MHz.The studies are based on the assumption that the BWS will operate on a TDD basis. WGSE members were requested to consider the preliminary report and to contribute to the next SE7 meetings, taking into account that the target date for the final approval of the new ECC Report is September 2011.
5.3 DECT
SE7 has started its activities on DECT in response the WGFM request (SE(11)003). SE7 has been asked to analyse how DECT equipment with 4 W or 36 dBm e.i.r.p. (250 mW output power together with 12 dBi antenna) would impact services in adjacent bands compared to DECT equipment with 24 dBm e.i.r.p. (250 mW output power together with 0 dBi antenna) for licence exempt use.
