  4. Abstract This presentation proposes to rename >=2MHz preambles in current TGah spec framework. Hongyuan Zhang, et. Al.

  5. May 2012 • In current Spec Framework, the two 2MHz preambles are named as “SU Preamble” and “MU Preamble”. • Issues with the names based on functionalities: • Current “MU preamble” is allowed to transmit both MU and SU packets (as in 11ac). • We propose to rename the two preambles using neutral names (e.g. based on preamble structures itself) instead of based on functionalities. • Propose to rename as “short preamble” and “long preamble”—similar to 11b. • Also need to rename some subfields in the long preamble Discussions Hongyuan Zhang, et. Al.

  6. May 2012 • Do you agree to rename the >=2MHz preambles as “Short Preamble” and “Long Preamble”, and rename the long preamble subfields as below? • Replace “MU Portion” by “Data Portion” • Replace “MU-STF” by “D-STF” • Replace “MU-LTF1~NLTF” by “D-LTF1~NLTF” Straw Poll - 1 “Omni” Portion Data Portion … STF LTF1 SIGA D-STF D-LTF1 D-LTF_NLTF SIGB DATA Field (2 symbols) (2 symbols as 11n GF) (2 symbols) (1 symbol) (1 symbol each) DGI LTS LTS Hongyuan Zhang, et. Al.

  7. May 2012 • Move to rename the >=2MHz preambles as “Short Preamble” and “Long Preamble”, and rename the long preamble subfields as below? • Replace “MU Portion” by “Data Portion” • Replace “MU-STF” by “D-STF” • Replace “MU-LTF1~NLTF” by “D-LTF1~NLTF” Motion - 1 “Omni” Portion Data Portion … STF LTF1 SIGA D-STF D-LTF1 D-LTF_NLTF SIGB DATA Field (2 symbols) (2 symbols as 11n GF) (2 symbols) (1 symbol) (1 symbol each) DGI LTS LTS Hongyuan Zhang, et. Al.
