doc.: IEEE 802.11-19/0754r0 May 2019 PAR Recap High throughput and low latency are two key requirements of EHT in the PAR of EHT[1]. The main candidate feature mentioned in the PAR [1] are: 320MHz bandwidth and more efficient utilization of non-contiguous spectrum, Multi-band/multi-channel aggregation and operation, 16 spatial streams and Multiple Input Multiple Output (MIMO) protocols enhancements, Multi-Access Point (AP) Coordination (e.g. coordinated and joint transmission), Enhanced link adaptation and retransmission protocol (e.g. Hybrid Automatic Repeat Request (HARQ)), If needed, adaptation to regulatory rules specific to 6 GHz spectrum Submission Slide 2 Ross Jian Yu (Huawei)
doc.: IEEE 802.11-19/0754r0 May 2019 Spectrum Recap For 5 GHz, two 160 MHz contiguous channels can be provided. For 6 GHz, 3 possible 320 MHz contiguous channels[NOTE], 4 possible 240MHz contiguous channels, 7 possible 160 MHz contiguous channels. Note: assume a 320 MHz contiguous channel can be formed by crossing two U-NII bands provided that the two U-NII bands are technically identical in terms of unlicensed regulatory requirements.

doc.: IEEE 802.11-19/0754r0 May 2019 Peak data rate analysis By considering the candidate feature in PAR, assuming 320 MHz, 16SS, 1024-QAM, the peak data rate is 38.4 Gbps. If 4K-QAM is further applied, the peak data rate can be 46.08 Gbps. Further taking into consideration of multi-band/multi-channel aggregation, the peak data rate can be: Link # BW configuration Peak data rate w/ 1K QAM w/ 4K QAM 2 links 320MHz + 320MHz 76.8Gbps 92.16Gbps 320MHz + 320MHz + 160MHz 96Gbps 115.2Gbps 3 links 320MHz + 320MHz + 320MHz 115.2Gbps 138.24Gbps 3 links 9 links 9*160MHz 172.8Gbps 207.36Gbps The achievable peak data rate considering 5GHz and 6GHz spectra is about 207Gbps. Further taking the complexity into consideration, a peak data rate of 100Gbps is feasible. Slide 4 Submission Ross Jian Yu (Huawei)
doc.: IEEE 802.11-19/0754r0 May 2019 Benefits and Necessity of Achieving 100Gbps From market point of view, from one generation to another, Wi-Fi should have larger data rate than cellular network of the same generation. Theoretically, 5G NR can already support 78.2 Gbps peak data rate. Cellular Wi-Fi 4G LTE-A vs 11ac Peak data rate 1Gbps 6.9 Gbps Peak data rate 4.89 Gbps per CC 78.2 Gbps over 16CCs (in FR1, sub 6 GHz) [2] 9.6 Gbps over 160MHz 5G NR vs 11ax BW 1.6 GHz for 16CCs 100 MHz per CC 160 MHz From application requirement point of view, in [3], for wireless VR applications, the PHY link Tput for raw stream or lightly compressed stream is >30 Gbps. For 3D ultimate immersion and lightly compressed rate, the required rate is 80.62 Gbps. Submission Slide 5 Ross Jian Yu (Huawei)
doc.: IEEE 802.11-19/0754r0 Mar 2019 Conclusion Benefits, necessity and feasibility for 11be to achieve a data rate of 100Gbps are discussed. The proposed method is good for 11be market promotion, can support VR applications for raw stream or lightly compressed stream. Submission Slide 6 Ross Jian Yu (Huawei)
