Wake up receiver frame
This disclosure describes systems, methods, and devices related to wake up receiver (WUR) frequency division multiple access (FDMA) transmission. A device may cause to send a wake up receiver (WUR) beacon frame on a WUR beacon operating channel to one or more station devices. The device may determine a first wake-up frame to be sent on a first WUR operating channel, wherein the first WUR operating channel is associated with one or more frequency division multiple access (FDMA) channels used for transmitting one or more wake-up frames to the one or more station devices. The device may determine to apply padding to the first wake-up frame based on a field included in a header of the first wake-up frame. The device may cause to send the first wake-up frame to a first station device of the one or more station devices.

decode a legacy signaling (L-SIG) field from the wake-up frame to extract a length value associated with the wake-up frame, wherein the length value is equal to a second length value of a second wake-up frame sent from an access point (AP) to a second station device (STA), wherein L-SIG indications of the various 20 MHz transmissions are set to a same value;
select a first indication of a first transition delay to start communication after receiving the wake-up frame;
