Methods and systems for reuse of a wireless medium during wake-up of a wireless device

An apparatus of an access point (AP) configured for wake-up radio (WUR) operations, the apparatus comprising:

• processing circuitry;
• and
• memory,
• the processing circuitry configured to:
• decode a frame received from a non-AP station (STA), the frame indicating that the non-AP station is a WUR STA and comprising a transition delay, the transition delay indicating a time that the non-AP STA takes to transition from a low-power state to an operable state;
• initiate a backoff procedure to contend for a wireless medium for transmission of a wake-up packet, the wake-up packet for transmission to a WUR of the non-AP STA;
• after transmission of the wake-up packet, wait a timeout interval for a transmission from the non-AP STA, the timeout interval being larger than the transition delay;
• initiate a backoff procedure for retransmission of the wake-up packet to the WUR of the non-AP STA when any transmission from the non-AP STA is not received within the timeout interval;
• and
• transmit a data packet to the non-AP STA when an acknowledgement from the non-AP STA is received within the timeout interval,
• wherein during the transition delay, the processing circuitry is configured to encode a transmission of a packet to a second non-AP STA.
