2 Submission doc.: IEEE /0327r0 March 2015 Jarkko Kneckt, NokiaSlide 2 Abstract The submission presents a microsleep mechanism that enables a non-AP STA to operate in Doze state while the channel is not available due to transmissions to other STAs. Submission r1 [1] discusses some challenges in power save mechanisms including microsleep.

3 Submission doc.: IEEE /0327r0March 2015 Jarkko Kneckt, NokiaSlide 3 Legacy microsleep Microsleep is a mechanism for a STA to be in Doze during other STAs transmissions STA knows that it cannot transmit or receive during the transmission Microsleep drastically reduces power consumption

4 Submission doc.: IEEE /0327r0 Microsleep and HE Simultaneous transmissions in HE make microsleep challenging A HE STA needs to be prepared to receive a transmission during an ongoing transmission Slide 4Jarkko Kneckt, Nokia March 2015

5 Submission doc.: IEEE /0327r0 HE microsleep solution HE STA can microsleep when it knows that it is not able to receive from HE AP The HE STA indicates the STAs whose transmissions block reception from the HE AP HE AP can microsleep when it knows that it cannot receive from any STA The HE AP indicates the STAs whose transmissions block reception from the HE STAs Slide 5Jarkko Kneckt, Nokia March 2015

6 Submission doc.: IEEE /0327r0 Motion Add following requirements to the section 6.1 Power Save of the SFD [2]: The HE STA shall be capable to indicate the STAs whose transmissions block reception from the HE AP. The HE AP shall be capable to indicate the STAs whose transmissions block reception from the HE STAs. Slide 6Jarkko Kneckt, Nokia March 2015
