PROPOSED DOCUMENT STRUCTURE FOR:
IMT VISION – “FRAMEWORK AND OVERALL OBJECTIVES OF THE FUTURE
DEVELOPMENT OF IMT FOR 2020 AND BEYOND”

This document has been agreed within the framework of CEPT ECC PT1

Introduction
At the last meeting of WP5D, the development of the working document towards PDNR
[IMTVISION] took place in three separate drafting groups, working on different sections of text.
In order to promote [IMT.VISION] to a PDNR at the 21st meeting of WP5D, the structure needs to
be stabilised at the next meeting (#20), so that the contributions to the 21st meeting can be limited
to refinements of the text.

Discussion
In the working document on [IMT.VISION] in Attachment 3.7 of 5D/726-E. text addressing one
issue is distributed in several different parts of the document, for example:
-
Text describing capabilities for future IMT can be found in sections 2.1, 2.3 and 4.3.
-
Some of the “usage scenarios” in section 2.1.1 are actually required capabilities.
-
There is confusion between usage scenarios, applications and services
-
Some of the “technology trends” are also capabilities.
-
Sections 4 and 5.1 both address objectives.
The current structure encourages this to continue as further sections are developed, for example:
-
Sections 4.1 and 5.1 both appear to address objectives.
-
Bands above 6GHz appear to have two aspects, spectrum and technology. The relevant
material on these aspects should therefore be included in these sections rather than in a
separate section.
Attachment 1 of this contribution (starting on page 3) contains a structure for [IMT.VISION] that
consolidates all of the material on one topic into a single section and has a logical sequence for
these topics.
For information, the current structure in Attachment 3.7 of 5D/726-E is shown for information in
Attachment 2 (starting on page 6), and the structure of the current Vision Recommendation, M.1645
is shown for information in Attachment 3 (starting on page 9).

Proposals
1) [IMT.VISION] should follow the structure described in Attachment 1 to this contribution.
2) The diagram summarising the capabilities that is currently being developed in a
correspondence group should be included in Section 9.1 “Objectives of the future
development of IMT for 2020 and beyond”.
