  4. Outline • 11ah is largely based on draft 2.0 of 11ac spec • We propose to add support for single user beamforming (BF) and MU-MIMO feedback and protocols as described in the current draft 11ac spec Ron Porat, Broadcom Slide 4

  5. Proposal • We propose to add to the spec framework a new section - 3.5 Transmit Beamforming • We propose to add in section 3.5 the following text: • The 802.11ah specification shall support, for all applicable BW, the SUBF and MU-MIMO feedback structure and protocol as specified in the following sections of IEEE P802.11ac™/D2.0 : • 8.4.1.46 VHT MIMO Control field • 8.4.1.47 VHT Compressed Beamforming Report field - contents of feedback frame • 8.4.1.48 MU Exclusive Beamforming Report field - contents of MU frame  • 9.31.5 VHT sounding protocol • 22.3.11 and its subsections: SU-MIMO and MU-MIMO Beamforming Ron Porat, Broadcom Slide 5
