10 Nov 2015 Motivation TDLS is an important direct STA-to-STA transmission format in Such direct STA-to-STA transmission can provide specific benefits, are attractive in terms of spectrum efficiency/reuse Conserves air interface resource Transmitting with high MCS TDLS operations could be easily adopted in 11ax environment because it needs no changes on 11ax PPDU format. It can exchange the setup frames using 11ax PPDUs The data exchanges between the TDLS peer can use the 11ax PPDUs An UL/DL indicator is presented in HE-SIG-A of SU PPDU for the power saving [1][2]: An UL/DL Flag field is present in the HE-SIG-A field of an HE SU PPDU. The UL/DL Flag field indicates whether the frame is UL or DL. The value of this field for TDLS is TBD. [PHY Motion 48, September 17, 2015] This proposal considers the flag in HE-SIG-A of the HE SU PPDU for TDLS. Yingpei Lin, Huawei Technologies

11 UL/DL Flag configuration for TDLS
Nov 2015 UL/DL Flag configuration for TDLS There is an UL/DL indicator field in HE-SIG-A for power saving. The value of this field for TDLS is TBD. An HE STA may enter the Doze state until the end of an HE SU PPDU if the value of the PPDU’s BSS COLOR field is equal to the BSS COLOR of its BSS, and the value of the UL/DL Flag field indicates that the frame is for uplink. The transmission direction should be indicated in HE-SIG-A if the TDLS data is transmitted in HE PPDU format: Option 1: Add a field to indicate the TDLS Identify the direct STA-to-STA link in HE-SIG-A directly explicitly; The space is very tight for the HE-SIG-A of SU PPDU; Option 2: Configure the UL/DL flag field as DL for TDLS PPDU Avoid the TDLS peer to enter the Doze. If the flag is configured as UL, the TDLS peer may not receive the TDLS data according to the current power saving mechanism; The TDLS peer can know the TDLS transmission by To DS and From DS fields in MAC header (To DS=0 and From DS=0 means a data frame direct from one non-AP STA to another non-AP STA within the same BSS ); Keep current design of HE-SIG-A; The DL flag can protect TDLS transmission taken spatial reuse from OBSS into account; We slightly prefer the option 2 because it does not add the new field in HE-SIG-A. Yingpei Lin, Huawei Technologies

12 Nov 2015 Conclusions The value of the UL/DL field in HE-SIG-A for TDLS can be configured as DL to avoid the TDLS peer enter the Doze state. The TDLS frame can be identified by To DS and From DS fields in the MAC header of the 11ax MPDU. Yingpei Lin, Huawei Technologies

13 Straw Poll Do you support to change the following words in SFD: Y/N/A
Nov 2015 Straw Poll Do you support to change the following words in SFD: An UL/DL Flag field is present in the HE-SIG-A field of an HE SU PPDU. The UL/DL Flag field indicates whether the frame is UL or DL. The value of this field for TDLS is TBD. The value of this field for TDLS is configured as DL. Note: The TDLS peer can identify the TDLS frame by To DS and From DS fields in the MAC header of the 11ax MPDU. Y/N/A Yingpei Lin, Huawei Technologies
