  4. Abstract This submission introduces an additional short-header frame format for IEEE 802.11ah Osama Aboul-Magd, Huawei Technologies

  5. Background • The subject of short-header frame has been discussed in the TG [1] • The TG has already added support for short-header format based on the use of AIDs for addressing [1] • This submission proposes a two-address short-header format that utilizes the full 6-byte MAC address. • All other header fields discussed in [1], i.e. Frame Control and Sequence Control are left unchanged.

  6. The Proposed Format Octets: 2 6 6 2 variable 4 • The proposed format is signaled by using a bit or a code point in the FC field • Determination of the bit or the code point is TBD. • The proposed format is useful when AID info is not available or cannot be used • Before and during association • Multicast transmissions • When Src MAC address is used to form CCMP nonce. Dest MAC Address Src MAC Address Sequence Control FC Body FCS Osama Aboul-Magd, Huawei Technologies

  7. Straw Poll • Do you support adding to the specification Framework; • “The draft specification shall define a frame format for the Short MAC Header as shown below. The indication of the format is tbd.”? Octets: 2 6 6 2 variable 4 Dest MAC Address Src MAC Address Sequence Control FC Body FCS Osama Aboul-Magd, Huawei Technologies

  8. Motion • Move to add to the specification Framework; • “The draft specification shall define a frame format for the Short MAC Header as shown below. The indication of the format is tbd.” Octets: 2 6 6 2 variable 4 Dest MAC Address Src MAC Address Sequence Control FC Body FCS Move: Second: Osama Aboul-Magd, Huawei Technologies
