Submission doc.: IEEE /0325r0 March 2012 Slide 1 TIM Enhancement With Group Bits Date: Authors: Zhong-Yi Jin, Nokia

Submission doc.: IEEE /0325r0 Abstract For 11ah, the traffic indication bitmap may need to be segmented and transmitted using multiple beacons [1] To support large networks with up to 6000 STAs Issue with segmented TIM A STA may need to wait for multiple beacon intervals before receiving its TIM bit Increased energy consumption for STAs Propose to enhance segmented TIM with group bits Slide 2Zhong-Yi Jin, Nokia March 2012

Submission doc.: IEEE /0325r0 Operations of segmented TIM For large 11ah networks, TIM needs to be segmented and transmitted using multiple beacon frames [1] TIM element size may be as big as 6000/8 = 750bytes Cannot serve a large number of STAs in one beacon interval Slide 3Zhong-Yi Jin, Nokia March 2012 Beacon TIM Segment 1Segment 2Segment N-1Segment N

Submission doc.: IEEE /0325r0 Issue with segmented TIM Increased energy consumption for STAs A STA may need to wait for multiple beacon intervals before receiving its TIM bit Slide 4 March 2012

Submission doc.: IEEE /0325r0 Enhance TIM with group bits Enable STAs to sleep after receiving 1 beacon frame Reserve some bits in traffic indication bitmap for groups 1 bit for each group of STAs A group bit is set if AP has buffered data for any of the STAs in the group Include group bits in every beacon frame STAs belong to groups without group bits set do not need to wait for the remaining TIM segments in subsequent beacon frames Grouping can be done implicitly/explicitly Based on the last N bits of AID Slide 5Zhong-Yi Jin, Nokia March 2012

Submission doc.: IEEE /0325r0 Use TIM group bits under light downlink traffic Allow STAs to save energy by sleeping immediately after receiving 1 beacon frame Probability that a group of STAs have 0 downlink data within 1 beacon interval (100ms) is high under light downlink traffic More efficient if STA with similar active times are grouped together Slide 6Zhong-Yi Jin, Nokia March 2012 # Downlink Packets /Min/STA Probably of 0 downlink for 50 STAs Probably of 0 downlink for 100 STAs

Submission doc.: IEEE /0325r0 Use TIM group bits under heavy downlink traffic AP cannot serve the downlink traffic for all STAs in one or more beacon intervals AP enables STAs to save energy by selectively clearing the group bits for certain groups that have buffered downlink data STAs in such group will: Go to sleep immediately after receiving 1 beacon frame Check TIM again at scheduled wakeup time Slide 7Zhong-Yi Jin, Nokia March 2012

Submission doc.: IEEE /0325r0 Conclusion Group bits can be used as an effective mean to reduce the energy consuption of STAs when segmented TIM is used in ah Slide 8 November 2011 Zhong-Yi Jin, Nokia

Submission doc.: IEEE /0325r0 Do you agree to add group bits to the TIM when segmented TIM is used? Slide 9Zhong-Yi Jin, Nokia March 2012 Straw Poll
