November 2016 Motivation In the last F2F meeting, related motion of the OBSS_PD SR backoff procedure was passed as below: When the receiving STA validates the conditions for spatial reuse operation by using OBSS_PD level, it shall invoke an SR backoff procedure by resuming the backoff counter countdown for the associated EDCAF as defined in EDCA backoff procedure. In this contribution, we want to clarify SR Backoff procedure for SR Delay Entry Jayh hyunhee Park, LG Electronics

SR delayed case SR Delay entry
November 2016 SR delayed case SR Delay entry If the inter-BSS PPDU is regarded as not having been received at all, the inter-BSS PPDU is HE SU PPDU or HE extended range SU PPDU, and the RXVECTOR parameter SPATIAL_REUSE of the HE SU PPDU or HE extended range SU PPDU is set to SR_Delay entry, the medium condition for the STA shall indicate BUSY for the duration of the HE SU PPDU or HE extended range SU PPDU. SR transmission is deferred, and UL MU is not disrupted Trigger frame is protected SR is not permitted during the length of an HE SU PPDU HE SIG-A field (SR field: SR delayed entry) SR transmission is deferred to the end of the PPDU SR is not permitted HE PHY Trigger frame HE SU PPDU HE trigger based PPDU AIFS and backoff procedure before spatial reuse transmission Jayh hyunhee Park, LG Electronics

Backoff procedure for SR delayed case
November 2016 Backoff procedure for SR delayed case In this case, the backoff procedure should be defined as below: The HE STA shall suspend the countdown of an existing backoff procedure till the end of HE SU PPDU After end of the HE SU PPDU, the STA may resume its backoff procedure HE SIG-A field (SR field: SR delayed entry) SR is not permitted SR transmission is deferred to the end of the PPDU HE PHY Trigger frame Backoff procedure is suspended HE trigger based PPDU Backoff procedure may be resumed Jayh hyunhee Park, LG Electronics

November 2016 Conclusion In this contribution, we clarify SR Backoff procedure for SR Delay Entry Jayh hyunhee Park, LG Electronics
16
November 2016 Straw poll Do you agree to add the following text in the 11ax spec draft? SRP-based Spatial reuse operation SR Backoff procedure for SR delayed case The STA may resume its backoff procedure after the end of the PPDU carrying the SR delay entry by following the procedure defined in HCF contention based channel access (EDCA) NOTE - The countdown of an existing backoff procedure is suspended until the end of the PPDU carrying the SR delay entry since the medium is BUSY during the duration of the PPDU carrying the SR delay entry.
