Proposal for EHT 320 MHz PPDU Support in EDCA Ranging for IEEE 802.11-23/0391r1
The document outlines a proposal to enable EHT 320 MHz PPDU support for EDCA ranging in IEEE 802.11-23/0391r1. It discusses the implementation of FTM legacy ranging, the importance of wider bandwidths, and the necessary changes in the standard to incorporate this support. The proposal aims to enhance range measurements and transition to non-TB and TB ranging protocols in the future.

March 2023 doc.: IEEE 802.11-23/0391r1 320 MHz EDCA Ranging PPDU Support (1) FTM legacy ranging, a.k.a. EDCA ranging in 802.11az, is currently the most implemented and deployed Wi-Fi time- of-flight ranging method. The non-TB and TB 802.11az style ranging protocols are only beginning to be implemented with no market presence to date. In the long run we would like to transition to the non-TB and TB 802.11az ranging protocols but for the time being many devices will only be supporting EDCA ranging. Thus, just as for non-TB and TB ranging, support for EDCA ranging at wider bandwidths is important to achieve sub meter range measurements reliably. Erik Lindskog, Samsung Submission Slide 2
March 2023 doc.: IEEE 802.11-23/0391r1 320 MHz EDCA Ranging PPDU Support (2) Non-TB and TB ranging requires many more HW and FW changes than ECDA ranging and therefore takes longer time to realize in the market. As such, it makes sense to enable the same wider bandwidths in EDCA ranging that we aim to realize in 11bk. We therefore propose to enable the EHT 320 MHz PPDUs for EDCA ranging as part of 11bk.

March 2023 doc.: IEEE 802.11-23/0391r1 Enabling 320 MHz EHT PPDU support The changes needed in the standard to enable EHT PPDUs for EDCA ranging are small. Mainly we need to add one or more rows to Table 9-320 (Format and Bandwidth subfield). This would include one or more rows for the 320 MHz EHT PPDU(s). Any extra rows are those that might be needed to support split bandwidths and/or multiple LO options. Erik Lindskog, Samsung Submission Slide 4
