doc.: IEEE /0654r0 Submission Outline Change bit width of CP+LTF in SIG-A Define options for trigger frame Revise options for NDP May, 2016 Slide 12Ron Porat, Broadcom, et. al.

doc.: IEEE /0654r0 Submission CP + LTF Field Bit Width Currently three mandatory and one optional options are defined: 1x LTF µS (optional and for full BW only) 2x LTF µS (mandatory) 2x LTF µS (mandatory) 4x LTF µS (mandatory) Those options were chosen to cover the entire spectrum from large delay spread outdoor channels It is generally preferable to keep the number of options low and currently no other options seem valuable. Hence we propose to reduce the bit width of that field from three to two to enable other fields to use that bit. May, 2016 Slide 13Ron Porat, Broadcom, et. al.

doc.: IEEE /0654r0 Submission NDP and Trigger Frame Currently only 2x LTF is defined for the NDP. It’s preferable to enable larger CP even for the NDP to support accurate BF calculation in the presence of large outdoor ISI. Hence we propose to support 4x LTF +3.2uS as an optional mode for the NDP packet The trigger frame conveys the CP+LTF options for UL Trig PPDU. Note that in this case 0.8uS is not considered a viable options because of timing difference between users (+/- 0.4uS is allowed by the spec) leading to large inter user interference. Hence we propose that the trigger frame signals the following three options 2x LTF uS (mandatory) 4x LTF uS (mandatory) 1x LTF uS for full BW only. 1x LTF is currently defined as optional for support. It is TBD whether it’s mandatory to transmit in UL Trig PPDU May, 2016 Slide 14Ron Porat, Broadcom, et. al.

doc.: IEEE /0654r0 Submission SP #1 May, 2016 Slide 15Ron Porat, Broadcom, et. al. Do you support to change the bit width of the CP+LTF field in SIGA for SU and MU to 2 bits? Yes No ABS

doc.: IEEE /0654r0 Submission SP #3 May, 2016 Slide 17Ron Porat, Broadcom, et. al. Do you support to define the following options to be signaled in the trigger frame for UL Trig PPDU 2x LTF uS (mandatory) 4x LTF uS (mandatory) 1x LTF uS for full BW only. TBD whether mandatory to transmit in UL Trig PPDU Yes No ABS
