1 doc.: IEEE /1516r0 Submission November 2011 Huai-Rong Shao, et.al. Samsung ElectronicsSlide ah Channelization Proposal for US Date: Authors:

2 doc.: IEEE /1516r0 Submission Abstract In this document we propose a revised transmission channelization in US for ah –Suggest twenty-six 1 MHz channels instead thirteen 1 MHz channels The lower 1MHz of each 2 MHz channel as primary 1MHz channel The higher 1MHz of each 2 MHz channel as secondary 1MHz channel The secondary 1MHz channel cannot be used unless none of the primary 1 MHz channels is available Slide 2Huai-Rong Shao, et. al, Samsung Electronics November 2011

3 doc.: IEEE /1516r0 Submission US Channelization (902 – 928MHz) November 2011 Slide 3Huai-Rong Shao, et.al, Samsung Electronics 902 MHz 928 MHz 1 MHz 2 MHz 4 MHz 8 MHz 16 MHz Note: Devices operating in the 1 MHz PHY mode are expected to operate in the lower 1 MHz of each 2 MHz wide channel Channels >= 4 MHz are right aligned to prevent interference on the 1 and 2 MHz channels at the lower edge of spectrum. From r1/1296-r3 (Rolf de Vegt, Qualcomm)

4 doc.: IEEE /1516r0 Submission Issues Un-resolved from Sept meeting Straw poll result: Yes: 24, No 17, Abstain 17 November 2011 Slide 4 Samsung Electronics Straw poll result: YES: 31 No: 11 Abstain: 15 Thirteen 1 MHz channels or twenty-six 1 MHz channels for ah in US? –Thirteen channels may be enough but we never know what will be for future applications

5 doc.: IEEE /1516r0 Submission US Channelization (902 – 928MHz) November 2011 Slide 5 Huai-Rong Shao, et.al. Samsung Electronics Note: The lower 1MHz of each 2 MHz channel as primary 1MHz channel and the higher 1MHz of each 2 MHz channel as secondary 1MHz channel The secondary 1MHz channel cannot be used unless none of primary 1 MHz channels is available Devices operating in the 1 MHz PHY mode shall support primary 1MHz channels and may support secondary 1MHz channels Channels >= 4 MHz are right aligned to prevent interference on the 1 and 2 MHz channels at the lower edge of spectrum. Coexistence rules between 2 MHz PHY mode and 1 MHz PHY mode TBD. Revised proposal:

6 doc.: IEEE /1516r0 Submission Straw poll: Channelization for US Do you agree with the following channelization for the US: Yes, No, Abstain November 2011 Slide 6Huai-Rong Shao, et.al, Samsung Electronics Note: The lower 1MHz of each 2 MHz channel as primary 1MHz channel and the higher 1MHz of each 2 MHz channel as secondary 1MHz channel The secondary 1MHz channel cannot be used unless none of primary 1 MHz channels is available Devices operating in the 1 MHz PHY mode shall support primary 1MHz channels and may support secondary 1MHz channels Channels >= 4 MHz are right aligned to prevent interference on the 1 and 2 MHz channels at the lower edge of spectrum. Coexistence rules between 2 MHz PHY mode and 1 MHz PHY mode TBD.
