Joint workshop of TG13 with ITU-T
May 2015 doc.: IEEE /0496r1 March 2018 Joint workshop of TG13 with ITU-T Joint meeting on February 7, 2018 in Geneva Objectives: both groups prepare similar technologies having similar timelines IEEE has more Li-Fi experts but no ecosystem yet ITU-T Q18/SG15 has few chipset vendors and own ecosystem in place IEEE includes HB-PHY according to G.hn recommendation Integration with MAC needs technical support from ITU-T Questions to ITU-T What PHYs are being used? How to resolve coexistence issues between different PHYs? Under what conditions G.hn PHY can be integrated into MAC? Volker Jungnickel (Fraunhofer HHI) Edward Au (Marvell Semiconductor)

Joint workshop of TG13 with ITU-T
May 2015 doc.: IEEE /0496r1 March 2018 Joint workshop of TG13 with ITU-T Nikola and Volker attended the joint meeting Volker presented status and timeline of TG13 It needs permission from ITU-T General secretary to copy any text, creating own text is not considered as a good idea If G.hn PHY is intended to be used, just use references IPR issues solved with SDO that owns the original text Exchange of drafts: ITU-T G.vlc members should get access to IEEE draft, TG13 members need access to ITU-T G.vlc draft Interaction through comments and resolution in each group Q (Bob): What time TG13 goes to letter ballot? Do we want to exchange documents and when? A: in October 2018 (TG draft D4 incl. MAC and all PHYs) see Volker Jungnickel (Fraunhofer HHI) Edward Au (Marvell Semiconductor)

Evaluation framework 1) Preamble
May 2015 doc.: IEEE /0496r1 March 2018 Evaluation framework 1) Preamble Detection probability (for false alarm rate = 0.1%) vs. SNR (cf. doc /r0) and required SNR where prob. of misdetection (timing error) <0.1% 2) Header BER vs. SNR for the header incl. 8B10B and RS(36,24) coding assuming random data for the header information 3) Payload BER vs. SNR for the payload incl. 8B10B or HCM and RS(255,248) coding assuming random data for the payload Results are expected for AWGN, D3 in scenario 3 and D7 in scenario 4 (Fig. 25) where LED1-6 are used together from CIRs: a companion file In case of questions, use TG13 reflector.
