May 2016 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 3rd party STAs and MPDU encoded by higher MCS may not be decoded by 3rd 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 Jeongki Kim et al.

Capacity of HE-SIG A Updated fields after the last March meeting
May 2016 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 Jeongki Kim et al. LG Electronics
13
Further considerations for TXOP
May 2016 Further considerations for TXOP Maximum duration TXOP should protect the following PPDU at least. E.g., the maximum duration of PPDU(aPPDUMaxTime) is ms It should be competitive value. Note that the maximum TXOP in LAA is 8ms 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 Jeongki Kim et al.

Conclusion We propose 7 bits TXOP field and 1 bit reserved field

Straw Poll Do you agree to add the following into SFD?
May 2016 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 7btis and 1 bit is reserved Jeongki Kim et al. LG Electronics
