The second meeting of project team D of the Conference Preparatory Group (CPG PTD) was held last 10-12 January in Helsinki, attended by about 58 participants, including the observer from the European Communications Office (ECO) and representatives from industry and/or operators.
CPG PTD is responsible for the following agenda items (AI) of the 2019 World Radiocommunication Conference (WRC-19):
- AI 1.1 (amateurs)
To consider allocation of 50-52 MHz spectrum for radio-amateur with secondary status. In Portugal the 50-52 MHz interval is already used by various amateur categories (secondary status). To accompany evolution of the band’s situation as it impacts the regulation of amateur service. The 50.5-51 MHz spectrum is conditioned;
Based on the discussions, the draft CEPT brief was updated, albeit without major changes until the sharing studies are updated: CEPT currently supports spectrum allocation for amateur service only if the spectrum requisites are justified and if the studies with incumbent services show that coexistence and compatibility between amateur service and radio location-finding and broadcasting services are possible.
- AI 1.11 (tracksides)
Spectrum harmonisation for the global system for mobile communications – railway (GSM-R). The International Telecommunication Union (ITU) working groups will evaluate spectrum needs as well as technical, operating and implementation conditions of systems for radiocommunication between trains and tracksides (Resolution 236 (WRC-15)). At CEPT reports have already been drawn up to allow coordination between GSM-R and the third generation mobile communications system;
The draft CEPT brief was updated based on the discussions; there was no consensus about CEPT’s position. For the time being two options are being debated to deal with this AI: by producing a recommendation of the ITU Radiocommunication Sector (without the need to modify the Radio Regulations (RR)) or by modifying the RR (by resolution or recommendation of the WRC).
- AI 1.12 (intelligent transport systems - ITS)
Harmonisation of the maximum possible amount of spectrum at regional or possibly global level to enable implementation of ITS in mobile service allocations (Resolution 237 (WRC-15)). In Europe, the 5875-5905 Mhz band is harmonised for ITS regarding passenger security aspects. At CEPT recommendation ECC/REC/(08)01, which establishes conditions for using ITS in the 5855-5875 MHz band, is still in effect;
The draft CEPT brief was updated based on the discussions, with information about the existing legal framework in CEPT. The drafting group will concentrate on accompanying the report of the group in charge of the studies associated to terrestrial mobile service, excluding international mobile telecommunications, amateur and amateur satellite (WP5A) services regarding ITS uses, and on obtaining and determining parameters needed to carry out studies on sharing between ITS and local radio area networks (RLANs), despite the existence of a report from the International Telecommunications Standards Institute – see AI.1.16;
It was also indicated that the working document of the draft ITU report (Report ITU-R M. (ITS USAGE) Intelligent transport systems usage Report in ITU Member States) being produced by WP5A does not contain updated information on CEPT.
- AI 1.16 (RLAN 5 GHz)
Issues associated to wireless access systems, including wireless access systems in radio local area networks, in the 5150-5925 MHz band, also producing regulatory actions, including additional spectrum allocation for mobile service (Resolution 239 (WRC-15)). At CEPT three reports have already been drawn up in this ambit, in response to a European Commission mandate (CEPT Report 57, ECC Report 244);
The draft CEPT brief was updated based on the discussions, taking into account the documents submitted, specifically on the studies that were conducted (but not completed, namely concerning active earth exploration by satellite services (EESS), the European Copernicus/Global Monitoring for Environment and Security project, radio location-finding and fixed satellite service) and were not included in CEPT Report 64 due to the lack of mitigation techniques;
Regarding the working document in support of the CEPT Brief, it was updated with the studies from Russia. A summary of the studies from CEPT Reports 57 and 64 was introduced and finally the result of a simplistic analysis from the United Kingdom which compares power spectral densities (PSD (dBW/MHz)).
- AI 9.1.5 (footnotes of RR 5.447F and 5.450A)
This agenda item is meant to investigate the impact on mobile service stemming from the amendment of footnotes 5.447F and 5.450A (concerning permission for mobile service use as long as it protects radio location-finding and radio-determination services and EESS), namely:
- removal of those reference footnotes to Recommendation M.1638-0 (characteristics of protection requisites for studies on sharing for radio location-finding, aeronautic radionavigation and weather radars operating in the 5250-5850 MHz band);
- introduction of new Recommendation M.1849-1 (technical and operational aspects of weather radars), which contains characteristics of new radars operating in the various sub-bands of 5250-5725 MHz, including protection criteria for weather radars operating in the 5350-5470 MHz band;
The draft CEPT brief was updated based on the discussions; CEPT’s position is being delineated so that introduction of the recommendations ITU-R M.1638.1 and ITU-R M.1849.1 in the footnotes of RR 5.447F and 5.450A will not create problems in existing RR allocations. Those same recommendations may nevertheless impact the characteristics of dynamic frequency selection (DFS), whereby the group is analysing whether changes to DFS will be necessary.
- AI 9.1.6 (wireless power transmissions)
To carry out urgent studies regarding wireless power transmission (WPT) for electric vehicles, specifically the impact of WPT on radiocommunication services, as well as to analyse harmonised frequency bands that minimise impact on radiocommunication services. These studies should take into account the discussions and standardisation procedures of the International Electrotechnical Commission, the Society of Automotive Engineers and the Organisation for Standardisation to harmonise WPT technologies in electric vehicles;
The draft CEPT brief was updated based on the discussions, with information on where the studies are taking place in ITU and CEPT and the frequency bands in question. A working document was also created as a support for the draft CEPT brief and European common proposals (ECPs), which will be annexed to the chair’s report.
The next meeting will be held on 3-5 May 2017 in Maisons-Alfort, France.
