4 doc.: IEEE 802.11-12/0816r0 Submission Motivation After channelization is done in US and other countries Channel selection rules need to be defined –Minimize interference between BSS –Maximize the usage of channels for different applications Slide 4Huai-Rong Shao, et. al, Samsung Electronics July 2012

5 doc.: IEEE 802.11-12/0816r0 Submission Slide 5 Among 26 MHz totally, only 4 MHz is being used in the above example But neither 8 MHz nor 16 MHz channels available, and only three 4 MHz channel available Problem Statement : Channel is being used : Channel not available : Channel available Huai-Rong Shao, et. al, Samsung Electronics July 2012

6 doc.: IEEE 802.11-12/0816r0 Submission Slide 6 If two 1 MHz channels are allocated to other positions One 16 MHz channel, two 8 MHz channels, and five 4 MHz channels available Problem Statement 902 MHz 928 MHz 1 MHz 2 MHz 4 MHz 8 MHz 16 MHz : Channel is being used : Channel not available : Channel available Huai-Rong Shao, et. al, Samsung Electronics July 2012

7 doc.: IEEE 802.11-12/0816r0 Submission Channel selection at BSS setup Among all available channels, the new BSS should select a idle channel which can help keep maximum number of idle (available) wider bandwidth channels after it is selected –The selected channel has least overlap with other wider bandwidth channels Channel availability is decided by channel scanning results –PHY design such as Mask may affect channel availability, for example, interference between adjacent channels Slide 7Huai-Rong Shao, et. al, Samsung Electronics July 2012

8 doc.: IEEE 802.11-12/0816r0 Submission Example of channel selection at BSS setup If adjacent channels are not treated as available from channel scanning results Slide 8Huai-Rong Shao, et. al, Samsung Electronics 902 MHz 928 MHz 1 MHz 2 MHz 4 MHz 8 MHz 16 MHz : Channel is being used : Channel not available : Channel available Choose one from these three if a new 1 MHz BSS needs to be set up : Channel not preferred due to adjacent channel interference July 2012

9 doc.: IEEE 802.11-12/0816r0 Submission Example of channel selection at BSS setup If interference between adjacent channels is low Slide 9Huai-Rong Shao, et. al, Samsung Electronics 902 MHz 928 MHz 1 MHz 2 MHz 4 MHz 8 MHz 16 MHz : Channel is being used : Channel not available : Channel available Choose one from these two if a new 1 MHz BSS needs to be set up July 2012

10 doc.: IEEE 802.11-12/0816r0 Submission Conclusion Channel selection rules need to be defined –Minimize interference between BSS –Maximize the usage of channels for different applications Channel selection at BSS setup stage –New BSS should select a channel which can help keep maximum number of available wider bandwidth channels Slide 10Huai-Rong Shao, et. al, Samsung Electronics July 2012

11 doc.: IEEE 802.11-12/0816r0 Submission Straw Poll Do you support to include the following channel selection rule in the 802.11ah specification framework document? –Among all available channels, the new BSS should select an idle channel which can help keep maximum number of idle (available) wider bandwidth channels after it is selected (Details TBD).
