3. doc.: IEEE 802.11-12/0025r1 Submission 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 January 2011 Rolf de Vegt (Qualcomm) Slide 3

7. doc.: IEEE 802.11-12/0025r1 Submission Sample Content of Spec Framework 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) January 2011 Rolf de Vegt (Qualcomm) Slide 7
