5. A method for supporting priority services at an 802.11 access point (AP) station (STA), comprising:
at an AP STA, entering a priority service mode and determining an amount of service reduction to impose upon non-priority non-AP STAs in communication with the AP STA;
transmitting, toward non-AP STAs in communication with the AP STA, one or more messages including a dot11priorityAccessAssertion information element (IE) including a dot11priorityAccessEnforced field and a durationOfdot11prioriyAccessEnforced field, and configured to cause a receiving non-priority STA to refrain from accessing a respective communication channel for an amount of time indicated by a duration value in the durationOfdot11prioriyAccessEnforced field; and
including in the dot11priorityAccessAssertion IE of the one or more messages an allowedCAPCduringpriorityAccess field configured to cause a receiving non-priority STA to refrain from accessing the communication channel if a target wake time (TWT) of the non-priority STA is not expiring during a current channel occupancy times (COT).
