Context and Introduction
• • •
TGai is getting closer to the stage whereby detailed technical proposals are being discussed The specification development process to be followed by the taskgroup has not yet been fully vetted and agreed upon by taskgroup membership This document contains a proposal to define a Spec Framework document as an official taskgroup deliverable which is developed and agreed upon by the taskgroup, prior to the creation of detailed spec text

Benefits of introducing a Spec Framework Document
• • •
Improves efficiency of spec text development Enables consensus building in the entire group Increases transparency of spec development

Document
Examples of Spec Framework document s:
– 802.11ac : 11-09/0992rxx – 802.11ah: 11-11/1137ry •
Sample Content of the .11ac Spec Framework Document:
A VHT mixed format (MF) preamble shall be supported in the draft specification and device support is mandatory. The VHT mixed format preamble shall have the following characteristics: R3.2.1.A: Robust legacy 11a deferral. The VHT MF preamble shall be designed such that a legacy 11a device will defer for the duration of the transmission to the same degree that it does for an HT MF preamble.
R3.2.1.D: The VHT MF preamble shall include training for a wider channel 1 to 8 spatial streams (see Section 3.4) DL MU-MIMO R3.2.1.E: Since the HT SIG field cannot be expanded without breaking backward compatibility, the VHT MF preamble shall include VHT SIG fields. The VHT SIG fields may include signaling for the following: a) wider bandwidth b) enhanced MCS (see Section 3.3) c) more spatial streams (see Section 3.4)

Strawpolls
doc.: IEEE 802.11-12/0025r1 1. TGai shall develop and adopt a Specification Development process (aka ‘Selection Procedure’) document (Y/N/A) 2. TGai shall create a Spec Framework document before developing a Draft Specification (Y/N/A)
