2. Motivation 16m has decided to develop SDD To provide guidance to the 802.16members to prepare relevant and timely contributions for the SDD, a process for developing SDD should be outlined. The following slides outline our proposal

3. System Description Document What is SDD? –A system view and architecture for the 802.16m air interface –SDD helps us develop a coherent, consistent and high quality 16m Standard and the 16m amendment document. –SDD helps us develop the initial IMT-Advanced proposals based on the architecture and technical concepts adopted SDD overall structure –Define System architecture Functional Split, Interfaces, Reference model –e.g., Section 4 Overall architecture (36.300), Functional components per layer What is Functional task, performance task for system? –SDD outline with prioritization : Table of contents of SDD Describe all essential and relevant technological concepts & how they fit within the overall architecture all technological items in IMT.TECH and other technological items to meet 802.16m requirements. Prioritization of technological items to facilitate developing functional components –E.g., multiple access, frame structure, etc –Functional components (PHY, MAC) Technical components descriptions

5. Steps for Developing SDD Outline of SDD (1~2 Sessions) –Table of Content –Define & describe 16m System Architecture & reference model –Define & Describe 16m Protocol Architecture –Define, categorize and prioritize Main functional components The prioritization would guide the 16m members to generate relevant and timely contributions The prioritization can be illustrated in a non-normative annex which would subsequently be removed once the SDD is matured. –Define functional sub-blocks and interconnections for each of the Main functional components. Develop the Core Sections of SDD (3~4 Sessions) –Based on the prioritized list, define and develop all the necessary functional components, protocols and procedures for 16m For example, start with PHY framework, MAC framework and then progress to detail functional sub-blocks, protocols and procedures. As one would expect, the Chair would issue call for proposals accordingly. The call may at Chair’s discretion contain prioritized list of topics based on the need and the progress of the SDD. Evaluation and Approval of SDD (1~2 Sessions) Finalize SDD draft Call for Comments on the SDD Finalization of SDD Note: the above steps may partially overlap
