November 2018 doc. : IEEE 802. 11 -18/1941 r 0 Abstract Summary of FD-TIG report and future work for the EHT SG. The FD-TIG report is document 11 -18 -0498 -08 -00 fd Submission Slide 2 James Gilb (GA-ASI, USD, Gilb Consulting Gen. XComm)

November 2018 doc. : IEEE 802. 11 -18/1941 r 0 Key Parts of the Report (11 -18 -0498 -08) • Section 2: Use cases • Section 4. 1. 2 FD MACs in research papers • Section 4. 3: Impact to 802. 11 standard • Section 4. 4: Prototype FD SIC systems • Section 5: FD Architectures • Section 6. 1: Throughput gains • Section 6. 2: Latency reduction • Section 6. 3: Collision reduction Submission Slide 3 James Gilb (GA-ASI, USD, Gilb Consulting Gen. XComm)

November 2018 doc. : IEEE 802. 11 -18/1941 r 0 FD-TIG/EHT • FD-TIG focused on applications in which self-interference cancellation (SIC) would be applicable – MAC changes would be the focus of the project. – Project can be done with minimal changes to the PHY • Probably define reserved bits in the header • Possibly FD-specific preamble • EHT – Many good presentations on FD with frequency division duplexing (FDD) – SIC may help FDD methods by reducing guard bands Submission Slide 4 James Gilb (GA-ASI, USD, Gilb Consulting Gen. XComm)

November 2018 doc. : IEEE 802. 11 -18/1941 r 0 Potential Focused Scope Statement “Defines methods for full-duplex operation of sub 7 -GHz PHYs in the same channel. ” Full-duplex using FDD could be in the same or different project. Submission Slide 5 James Gilb (GA-ASI, USD, Gilb Consulting Gen. XComm)

November 2018 doc. : IEEE 802. 11 -18/1941 r 0 Straw Poll #1 Full duplex in same channel should be part of a new amendment project, either as a standalone project or as a part of EHT, starting 2019 – yes – no – don’t care Vote only for 1 option Submission Slide 6 James Gilb (GA-ASI, USD, Gilb Consulting Gen. XComm)

November 2018 doc. : IEEE 802. 11 -18/1941 r 0 Straw Poll #2 Which option do you support: – Option 1: Standalone project on full duplex – Option 2: EHT project should include full duplex – Option 3: none of above May vote for more than 1, vote by option #. Submission Slide 7 James Gilb (GA-ASI, USD, Gilb Consulting Gen. XComm)

doc. : IEEE 802. 11 -18/1941 r 0 Future plan for FD-TIG? • Straw poll in FD-TIG – If FD becomes a part of EHT project, do you support the continuation of a separate FD-TIG to provide a focused group to discuss FD issues? – Not too many yes, a lot no. • Three possibilities: – Support for separate SG – work done in SG – Support for being a part of EHT – work done in EHT – No support, FD-TIG has finished its work.
