    Abstract: A method for transmitting a high priority (HP) packet from a first wireless device to a second wireless device is described. The method includes determining the presence of an HP packet for uplink transmission; determining that a communications link that uses a wireless medium for transmitting the HP packet is busy; generating a preemption request message in a frame; and transmitting the frame with the preemption request message to the second wireless device. The first wireless device can receive from the second wireless device an indication that the preemption request was accepted, such as by receiving a trigger frame with resource allocation for transmitting the HP packet or an indication of the end of a contention free period, to allow the first wireless device to contend for channel access to transmit the HP packet.

    Abstract: An interface circuit in an electronic device (such as an access point) may utilize a configurable wake-up-frame format. During operation, the interface circuit may receive a wake-up-radio (WUR)-setup request associated with a recipient electronic device, where the WUR-setup request specifies a proposed configurable wake-up-frame format. In response, the electronic device may determine the configurable wake-up-frame format to be used based at least in part on the proposed configurable wake-up-frame format. Then, the interface circuit may provide a WUR-setup response intended for the recipient electronic device, where the WUR-setup response specifies the configurable wake-up-frame format selected for use. Note that the configurable wake-up-frame format may specify a payload length in a wake-up frame and/or one or more operations of at least one of the recipient electronic device or the electronic device after the wake-up frame is transmitted by the electronic device.
