ITU-R is invited to study, as a matter of urgency, the applicability of the limit specified in No. 21.5 of the Radio Regulations to IMT stations, that use an antenna that consists of an array of active elements, with a view to recommend ways for its possible replacement or revision for such stations, as well as any necessary updates to Table 21-2 related to terrestrial and space services sharing frequency bands.<\/em><\/p>\n\n

Furthermore, the ITU-R is invited to study, as a matter of urgency, verification of No. 21.5 regarding the notification of IMT stations that use an antenna that consists of an array of active elements, as appropriate. (Responsible Group: WP 5D)<\/em><\/p>\n\n

APT View:<\/strong><\/p>\n\n

The APT has considered the studies on WRC-19 Document 550 but has not developed any\u00a0 APT Common Proposal on the matter. However, the APT has agreed on the following views:<\/p>\n\n

    \n
  • APT Members are of the view that possible and practical alternative approaches\/solutions merit to be considered.<\/li>\n\n
  • APT Members are of the view that appropriate regulatory provisions\/measures for the operation of terrestrial IMT and space services and their future development in a balanced and fair manner are necessary.<\/li>\n\n
  • APT Members are of the view that change to RR No. 21.5 may not be necessary at this stage to address the issues raised in Document 550 of WRC-19.<\/li>\n<\/ul>\n

    APT Common Proposal: None<\/strong><\/p>\n
