Hi Alfred,

Can you please queue the following SPs for MAC. They follow up on my earlier contribution 11-23/1873 Post-FCS MAC Padding?

Do you agree that the I-FCS in a Trigger frame is included as part of 2 contiguous User Info fields known as I-FCS User Info fields?
Do you agree that the AID in these 2 I-FCS User Info fields have the same special AID12 value of 2009?
Do you agree that the 32 bits of the actual I-FCS are distributed between the 2 I-FCS User Info fields keeping 24 bits in first User Info and 8 bits in second User Info?
Do you agree that the I-FCS bits in each I-FCS User Info field start on the byte boundary after leaving a gap of 4 reserved bits after the AID12 field?
Do you agree that the input to the I-FCS computation covers all bytes from the Frame Control field up to and including the last User Info that precedes the I-FCS, but not including anything in the I-FCS User Info fields or later?

The input of the I-FCS does not cover any of the fields starting from the first IFCS User Info field

Do you agree that the I-FCS User Info fields appear after all User Info fields that are addressed to STAs that require the inclusion of I-FCS?
Do you agree that the PN and MIC in a Trigger frame are included in 8 contiguous dedicated User Info fields, and that the first 2 User Info fields carry the 6-bytes of the PN field in fragments of 3 bytes; and the following 6 User Info fields carry the 16-bytes of the MIC field in fragments of 3 bytes each, except for the last user info field that contains the last 1 byte of the MIC field

Within these dedicated User Info Fields, the 4 bits [B12-B15] after the AID12 field are reserved to align on the byte boundary followed by either 3 bytes of content [B16 to B39] or 1 byte of content [B16 B23]?

Sindhu

Hi Alfred,

Could you please update my one of SPs below?

SP#4: Do you agree to include the following into the 11bn SFD?
In response to BSRP Trigger frame transmitted by a non-AP STA, an AP transmits a Multi-STA BlockAck frame
–        Block Ack Starting Sequence Control subfield and Block Ack Bitmap subfield are not present if there is no any feedback information
–        Values of Ack Type and TID are TBD

Hi Alfred,

Happy New Year!!!

Could you please add the following contribution to the MAC Queue?
[Control] 11-25/0062r0 More Consideration for feedback information    Hongwon Lee(LG Electronics)

Could you also please add the following SPs to the MAC Queue?

SP#1: Do you agree to include the following into the 11bn SFD?
A TXOP holder transmitting a BSRP Trigger frame as an ICF which is addressed to at least a UHR STA that enabled a dynamic unavailability operation mode, shall ensure that UL Length sets to a sufficient length for PPDU that contains a Multi-STA BA as an ICR including unavailability information
Supporting documents: [24/1464]

SP#2: Do you agree to include the following into the 11bn SFD?
When a STA intends to indicate unavailability in a BSRP Trigger frame as an initial control frame (ICF), the unavailability consists of:
–        Unavailability Target Start Time field that indicate the start time in TSF when the STA becomes unavailable and uses 9 bits with a granularity of 64us, and
–        Unavailability Duration field that indicates the time during which the STA is unavailable and uses 9 bits with a granularity of 64us
Supporting documents: [24/1464]

SP#3: Do you agree to include the following into the 11bn SFD?
When a STA intends to indicate unavailability in a BSRP Trigger frame as an initial control frame (ICF), the unavailability is indicated in a Special User Info field with an AID
–        The AID is TBD (but not 2007)
Supporting documents: [24/1464]

SP#4: Do you agree to include the following into the 11bn SFD?
In response to BSRP Trigger frame transmitted by a non-AP STA, an AP transmits a Multi-STA BlockAck frame in which Block Ack Starting Sequence Control subfield and Block Ack Bitmap subfield are not present
–        Values of Ack Type and TID are TBD
Supporting documents: [24/1464]
