The 12th meeting of the CPG PT-D group was held last 20-22 September in London, chaired by Steve Bond. In the CEPT scope CPG PT-D group was the body in charge of preparing points 1.5 (ENG), 1.7 (MSS in 1525-1559 MHz and 1626.5-1669.5 MHz and spectrum availability studies for AMS®S), 1.8 (SF above 71 GHz), 1.17 (790-862 MHz), 1.18 (issues associated to the Galileo system), 1.20 (HAPS) and 1.25 (issues associated to MSS) on the agenda of the 2012 World Radiocommunication Conference (WRC-12).
Due to the closeness of WRC-12 (23 January to 17 February 2012), and also because this was the group’s last ‘calendar’ meeting, efforts were made to reach consensus during the meeting on items not resolved at the previous meeting. The following European common proposals (ECPs) were thus prepared, debated and endorsed for submission to the next meeting of the CPG group:
- AI 1.7: developed an ECP indicating that future spectrum needs for aeronautic mobile satellite (route) service (AMS®S) can be accommodated in the 2x10 MHz identified in RR footnote 5.357A, without limiting systems operating according to the RR; the solution as developed is a compromise between NOC (no change) and modification of Res.222 (Rev.WRC-07) to change spectrum access procedures; given that the compromise was not total, the ECP’s points in disagreement will be submitted to the CPG so that a final decision can be made;
- AI 1.17: as requested by the CPG, two ECPs were drawn up to deal with Issue B (mobile vs. ARNS): one based on method B1 and the other on B2 from Report CPM11-2; two proposed triggers to start a co-ordination process were defended: aggregated field and co-ordination distances (defended by Russia), and aggregated field and field intensity (defended by other CEPT countries); the co-ordinator proposed two options: (i) insert aggregated field in Annex 1 of Resolution 749, and (ii) consider the greatest distances set out in the bilateral agreements (or worst case), with the final decision up to the CPG;
- AI 1.25: single ECP aiming not to change the RR with respect to possible new MSS allocations between 4 GHz and 16 GHz; also debated was the possibility of allocating with secondary status the 15 GHz band to MSS, but industry showed no interest in that scenario; the ECP was consequently completed with NOC proposed between 4 GHz and 16 GHz for MSS.
The texts of the briefs on all WRC-12 agenda items under PT-D’s charge were also updated, thereby completing the CPG PT-D group’s work for the WRC-12 World Conference.
