  • Publication number: 20250254613
    Abstract: An embodiment includes an access point (AP) that can perform state transitions while operating in dynamic power save, whereby the AP determines that it is able to transition between reduced and enhanced operating parameter states while not causing loss of medium synchronization at the AP and while preventing loss of frames, including by either transmitting a frame to itself to set a duration that is sufficient to perform the state transition or by requesting assistance from a station (STA) in order to perform the state transition, or by identifying an ongoing transmission not addressed to the AP during which the transition can be performed.

  • Publication number: 20250234311
    Abstract: An electronic apparatus comprises a memory and a processor operably coupled to the memory and supporting a first non-AP station. The electronic apparatus generates timing information indicating when a packet is expired and transmits the packet to a first access point (AP) which the first non-AP station is associated with. The electronic apparatus transmits the timing information to the first AP. The timing information enables the first AP to transmit the packet based on the timing information to a second non-AP station associated with the first AP or enables the first AP to transmit the packet based on the timing information to a second AP so that the second AP transmits the packet to a third non-AP station associated with the second AP.

  • Publication number: 20250234373
    Abstract: A first access point (AP) participates in a multi-AP coordination for a first target wake time (TWT) schedule established by a second AP. The first AP advertises, to one or more stations (STAs) within a basic service set (BSS) of the first AP, a TWT schedule that is identical to the first TWT schedule established by the second AP. When a second TWT schedule is established by the second AP, the first AP advertises, to the one or more STAs within the BSS of the first AP, a TWT schedule that is identical to the second TWT schedule established by the second AP. Alternatively, when one or more second TWT schedules are established by the second AP, the first AP determines whether to advertise the one or more second TWT schedules on a per-TWT schedule basis.
