May 2016 doc. : IEEE 802. 11 -16/0636 r 0 Introduction • TXOP field

May 2016 doc. : IEEE 802. 11 -16/0636 r 0 Introduction • TXOP field is carried in HE-SIG A of HE PPDUs to protect the TXOP including the PPDU but the details of the field is TBD – Note that MPDU of HT TB PPDU is not decoded by the 3 rd party STAs and MPDU encoded by higher MCS may not be decoded by 3 rd party STAs • Because HE-SIG A has the limited space, we need to decide the size of TXOP fields considering the capacity of HE-SIG A Submission Slide 11 Jeongki Kim et al. LG Electronics

May 2016 doc. : IEEE 802. 11 -16/0636 r 0 Capacity of HE-SIG A

May 2016 doc. : IEEE 802. 11 -16/0636 r 0 Capacity of HE-SIG A • Updated fields after the last March meeting – BW fields in HE MU PPDU: 3 bits (considering channel bonding) [1] – CP and LTF Type: 3 -> 2 bits [2] – SR field: 4 bits [3] • Total remaining bits – 9 bits in HE SU PPDU and 8 bits in HE MU PPDU • Like legacy system, 1 bit can be reserved for future extension • We propose 7 bits TXOP Duration field Submission Slide 12 Jeongki Kim et al. LG Electronics

May 2016 doc. : IEEE 802. 11 -16/0636 r 0 Further considerations for TXOP

May 2016 doc. : IEEE 802. 11 -16/0636 r 0 Further considerations for TXOP • Maximum duration – TXOP should protect the following PPDU at least. E. g. , the maximum duration of PPDU(a. PPDUMax. Time) is 5. 484 ms – It should be competitive value. Note that the maximum TXOP in LLA is 8 ms in coexistence scenario • Granularity – Based on the size and the maximum value, the granularity and the number of granularity will be decided – The larger granularity, the larger overprotection degrade the efficiency , especially for short packets • The details for them will be revisited at the next meeting Submission Slide 13 Jeongki Kim et al.

May 2016 doc. : IEEE 802. 11 -16/0636 r 0 Conclusion • We propose 7 bits TXOP field and 1 bit reserved field Submission Slide 14 Jeongki Kim et al. LG Electronics

May 2016 doc. : IEEE 802. 11 -16/0636 r 0 Straw Poll • Do you agree to add the following into SFD? – In HE-SIG-A of HE (extended range) SU PPDU/HE MU PPDU/HE trigger-based PPDU, the size of TXOP Duration field is 7 btis and 1 bit is reserved Submission Slide 16 Jeongki Kim et al. LG Electronics
