March 2016 doc.: IEEE 802.11-16/0358r1 Introduction Maximum A-MPDU size that a VHT STA can announce is 220 octets. Maximum MPDU size that a VHT STA can announce is 11454 octets. Maximum number of MPDUs in an A-MPDU is 64. The Maximum number of MPDUs in multi-TID A-MPDU may be more than 64. Accordingly, maximum A-MPDU size should be increased if there is no PHY restriction. Submission Slide 9 Liwen Chu et. al.
March 2016 doc.: IEEE 802.11-16/0358r1 PHY Restriction to A-MPDU Size The max A-MPDU duration in HE PPDU is limited by the max number of symbols indicated by L-SIG length, which is 5.484ms. aPSDUMaxLength in VHT PPDU is 4 692 480 octets aPSDUMaxLength in HE PPDU should be more than aPSDUMaxLength in VHT PPDU because of less percentage GI overhead in HE OFDM symbol. Data symbols in an HE PPDU shall use a DFT period of 12.8 s. Data symbols in an HE PPDU shall support guard interval durations of 0.8 s, 1.6 s and 3.2 s. Variable durations per HE-LTF symbol 4 s 8 s 4 s 4 s 8 s 8 s ...

March 2016 doc.: IEEE 802.11-16/0358r1 MPDUs of Multi-TID A-MPDU/BA Originally, BA negotiation negotiates buffer size for one TID. At most 64 MPDUs can be transmitted in an A-MPDU. With multi-TID BA, a multi-TID BA can acknowledge at most 64*8 MPDUs. With super BA and multi-TID BA, a multi-TID BA can acknowledge at most 256*8 MPDUs. Submission Liwen Chu et. al.
March 2016 doc.: IEEE 802.11-16/0358r1 Maximal A-MPDU Size In 11ac, the maximal A-MPDU length is 220=1,048,576 bytes. This is enough for 11ac since the maximal MPDU length is 11454bytes and the maximal receiving buffer size of a block ack is 64 (11,454*64=733,056). With multi-TID BA and/or super BA, 1,048,576 bytes are not enough if one A- MPDU has large number of MPDUs, e.g. 256 MPDUs (11,454*256=2,932,224). We propose a HE device can announce two maximal A-MPDU length 221, 222 octets besides maximal A-MPDU length in VHT Capabilities element. Submission Liwen Chu et. al.
March 2016 doc.: IEEE 802.11-16/0358r1 Straw Poll Do you support adding the following text to 11ax SFD: A HE STA can announce its maximum A-MPDU length limits to 221, 222? Submission Liwen Chu et. al.
