IEEE 802.11-24 Discussion on Feature Re-use in 802.11bp
In this contribution, Vytas Kezys from HaiLa Technologies discusses the re-use of existing IEEE 802.11 design features for implementation in 802.11bp. The background emphasizes the harmonization of waveform design to streamline 802.11bp, with a focus on leveraging features like 802.11ba for downlink. Further, the document explores utilizing 1Mb/s DSSS for backscatter uplink and the benefits of using Enhanced Broadcast Service (EBCS) and HE/EHT mechanisms in non-infrastructure traffic protection.

July 2024 doc.: IEEE 802.11-24/1210r0 802.11 Feature Re-use Date: 2024-07-12 Authors: Name Vytas Kezys Affiliations HaiLa Technologies Address Phone email vytas@haila.io Submission Slide 1 Vytas Kezys, HaiLa Technologies
July 2024 doc.: IEEE 802.11-24/1210r0 Abstract In this contribution, we discuss the re-use of existing IEEE802.11 design features for use in 802.11bp. Submission Slide 2 Vytas Kezys, HaiLa Technologies
July 2024 doc.: IEEE 802.11-24/1210r0 Background Harmonization of Waveform has been proposed to streamline the design of 802.11bp [1] An additional approach is to leverage existing 802.11 features One such re-use has already been proposed: the use of 802.11ba (WUR) for the downlink [2] Further existing features could be considered Submission Slide 3 Vytas Kezys, HaiLa Technologies
July 2024 doc.: IEEE 802.11-24/1210r0 1Mb/s DSSS for Backscatter Uplink After .11ba downlink sequence, a 1Mb/s DSSS frame is also transmitted. This frame is then backscattered by the AMP STA to provide the uplink Advantages: infrastructure participating in AMP re-use existing TX and RX blocks non-AMP infrastructure (existing STAs) can be used for uplink RX of all existing waveforms, 1Mb/s DSSS offers best link-budget and is constant envelope infrastructure forms frame AMP STA only changes bits on backscatter (low complexity, low power) 1Mb/s DSSS could also be used for active transmit Use of DSSS for backscatter does NOT require DSSS beacons / preambles Submission Slide 4 Vytas Kezys, HaiLa Technologies
July 2024 doc.: IEEE 802.11-24/1210r0 802.11bc 802.11bc Enhanced Broadcast Service (EBCS) can be used on both up- and down- link [3] Advantages: avoids the need/overhead of association security specific to .11bp can be used for protection ease and flexibility of deployment no beacons to clutter network PHY agnostic use EBCS with 11ba PHY Submission Slide 5 Vytas Kezys, HaiLa Technologies
July 2024 doc.: IEEE 802.11-24/1210r0 HE / EHT mechanism for protecting non-infrastructure traffic Adapt (R)TWT for AMP communication [4] can help reduce power consumption of AMP STA for low/periodic traffic Adapt channel usage request/response to allocate medium for AMP communication [3,4] Submission Slide 6 Vytas Kezys, HaiLa Technologies
July 2024 doc.: IEEE 802.11-24/1210r0 Conclusions Many opportunities to leverage existing 802.11 features in building an 11bp amendment. Leveraging existing 801.11 features: eases implementation provides better interoperability between 802.11bp devices and other 802.11 devices provides flexibility in deploying 11bp networks with traditional 802.11 networks. leverage 802.11 features that have been adopted and proven-out Submission Slide 7 Vytas Kezys, HaiLa Technologies
