6、, required for the next World Radiocommunication Conference; C2: urgent studies, expected to be required for other radiocommunication conferences; S: Questions which are intended to respond to: matters referred to the Radiocommunication Assembly by the Plenipotentiary Conference, any other conferenc
7、e, the Council, the Radio Regulations Board; advances in radiocommunication technology or spectrum management; changes in radio usage or operation: S1: urgent studies which are intended to be completed within two years; S2: important studies, necessary for the development of radiocommunications; S3:
8、 required studies, expected to facilitate the development of radiocommunications; Res.

9、ropriate categories to Questions which are related to the decisions of the conference or to the agendas of future world or regional radiocommunication conferences. 2 that Questions identified as suitable for approval by the alternative procedure according to Resolution ITU-R 45 should be within the
10、categories S1, 2 or 3; such Questions shall be identified as “/AP”; 3 that, as early as possible in the study period, the Study Groups shall identify which of their Questions, if any, are suitable for approval by the alternative procedure according to Resolution ITU-R 45. Identification of Questions
11、 using this procedure is subject to being approved, without opposition, by correspondence. This approval procedure for the identification of Questions should not delay the starting of the process for the approval of Recommendations under the alternative procedure in accordance with Resolution ITU-R
12、45; 4 that the work programme for the next study period shall include the Questions listed in Annexes 1 to 6 with Categories C and S. These Questions shall be referred to the appropriate Study Groups. The texts of the Questions listed in Annexes 1 to 6 are to be found in Document 1 of the series of
13、documents for the next study period of the appropriate Study Group taking into account considering e); 5 that the work programme shall also include studies, within the scope of the Study Group, on matters relevant to agenda items of WRCs or RRCs, or to WRC Resolutions; 6 that Conference-oriented Que
14、stions for study by the Study Groups shall: address topics seeking a Recommendation or a report to a conference; address a single specific issue; include a specified target date for the output; 7 that each Question shall: indicate in a concise form the reason for the study; specify the scope of the
15、study as precisely as possible; indicate the form in which the response should be prepared (e.g. as a Recommendation or other text, etc.) and, when possible, an outline of the contents of the expected response; specify the date when a complete or partial response is needed or the time period for the
16、 study, together with the milestones for the progress of the study; be modified to take account of partial answers; identify relevant Study Groups working in closely related areas, to which the text of the Question should be sent for consideration; 8 that Study Groups shall consider all their Questi
17、ons and make proposals to each Assembly: so as to bring them into conformity with further resolves 2 and 3; for the identification and categorization of Questions; for the deletion of Questions, where the study has been completed, where no contributions are expected within the next study period, or,
18、 in conformance with Resolution ITU-R 1, 1.7, where no contributions have been made; such Questions shall be identified as category D; Res. ITU-R 5-5 3 9 that each Study Group shall report to each Radiocommunication Assembly the progress that has been made in respect of each Question allocated to it
19、 with categories C1, C2 or S1; 10 that, as a part of the work programme, a Study Group may also undertake studies, within the scope of its mandate, for the revision of an existing Recommendation or on a topic for which a new Question would normally be required. Where such study is expected to contin
20、ue beyond the date of the next Radiocommunication Assembly, an appropriate Question should be drafted for approval by the Assembly, further resolves 1 that the Study Groups, when reviewing Questions assigned to them in accordance with Resolution ITU-R 4 and this Resolution, should reach unanimous co
21、nclusions, and should use the following guidelines: a) Questions which are within the mandate of the ITU-R: this guideline ensures that Questions and their associated studies are related to the conduct of radiocommunication matters, i.e., per ITU Convention, Article 11, Nos. 150-154 and 159, “a) use
22、 of the radio-frequency spectrum in terrestrial and space radiocommunication and of the geostationary-satellite and other satellite orbits; b) characteristics and performance of radio systems; c) operation of radio stations; and d) radiocommunication aspects of distress and safety matters and ITU Co
23、nvention, Article 11 No. 159”. However new or revised Questions, when adopted, shall not include any reference to spectrum matters covering proposals on allocation unless requested under a Radiocommunication Assembly agenda item relating to the Question, or in a WRC Resolution seeking studies by ITU
24、-R; b) Questions that relate to work being conducted by other international entities: if such work is being conducted elsewhere, the Study Group should liaise with such other entities, in accordance with Resolution ITU-R 1, 5.4, and Resolution ITU-R 9 to determine the most appropriate way to conduct
25、 the studies, with a view to taking advantage of external expertise; 2 that the Study Groups will evaluate draft new Questions proposed for adoption against the same guidelines set forth in further resolves 1 and will include such evaluation when submitted to Administrations for approval according t
26、o Resolution ITU-R 1; 3 that the Study Groups will grant a high priority for the continuation of their work to the Questions meeting guidelines defined in further resolves 1, with an intent to manage as efficiently as possible the scarce resources of the ITU, taking into account the need to give app
27、ropriate priority to topics addressed to them by relevant ITU bodies, such as PPs, WRCs, and the RRB, invites 1 administrations to use the guidelines indicated in further resolves 1, above, in their determination of whether or not a Question is appropriate for approval.
