March 2019 MAC Architectures for EHT Multi-band Operation doc.: IEEE 802.11-19/0360r0 Date: 2019-03-12 Authors: Name Sharan Naribole Affiliations Address Samsung Phone email n.sharan@samsung.com srini.k1@samsung.com Srinivas Kandala Samsung wookbong.lee@samsung. com ashok.r@samsung.com Wook Bong Lee Samsung Ashok Ranganath Samsung Submission Slide 1 Sharan Naribole (Samsung), et.al.,
March 2019 doc.: IEEE 802.11-19/0360r0 Introduction Multi-band Operation One of candidate features discussed in EHT TIG/SG Traffic steering, single association/authentication state, multi-band aggregation, etc. (Appendix) In this presentation, We classify the potential architectures : Independent MAC, Distributed MAC, Unified MAC Review operations that can be supported by these architectures Submission Slide 2 Sharan Naribole (Samsung), et.al.,
March 2019 doc.: IEEE 802.11-19/0360r0 Independent MAC Independent MAC-SAP, association state, MLME, data plane Asynchronous transmission Upper layer link aggregation (e.g. 802.1AX-2014) for load balancing and traffic steering Non-transparent FST [7] Submission Slide 3 Sharan Naribole (Samsung), et.al.,
March 2019 doc.: IEEE 802.11-19/0360r0 Distributed MAC Single MAC-SAP, authentication Shared management info, sequence counter, PN counter, etc. Independent per-band queueing Single association state, Data/MGMT split (e.g. idle mode in band A/active mode in band B, update system information in band A only, etc.) Transparent FST [7] Submission Slide 4 Sharan Naribole (Samsung), et.al.,
March 2019 doc.: IEEE 802.11-19/0360r0 Unified MAC Single MLME and MAC Sublayer Unified queueing Synchronous transmission, MAC retransmissions on other bands, buffer status/ CCA status indications of band A on band B Submission Slide 5 Sharan Naribole (Samsung), et.al.,
March 2019 doc.: IEEE 802.11-19/0360r0 Summary Independent MAC, Distributed MAC, Unified MAC Multi-band operation features supported varies among the architectures Encourage discussion: EHT multi-band device reference model to assist technical contributions on multi-band operation Submission Slide 6 Sharan Naribole (Samsung), et.al.,
