Abstract: This disclosure provides methods, devices and systems for identifying wake-up signals. Some implementations more specifically relate to PHY preamble designs for wake-up signals such as Wake-Up Radio (WUR) packets conforming to IEEE 802.11ba. In some implementations, the preamble designs can include a combination of modulation schemes, data rate indications and length indications enabling devices capable of receiving and decoding wake-up signals to identify the signals as wake-up signals (for example, WUR packets), while ensuring that devices not capable of receiving and decoding wake-up signals identify the wake-up signals as legacy packets, or otherwise not WUR packets.
