A method and apparatus to estimate and mitigate platform noise incurred at a wireless device coupled to the platform. A computing device includes a platform including a first processor, a wireless device coupled to the platform, the wireless device including a second processor, and a plurality of antennas coupled to the wireless device. At least one of the first processor or the second processor is configured to determine characteristics of a platform noise incurred at the wireless device in real-time due to utilization of circuitries and processing components on the platform and implement an adaptive real-time and application/context-aware measure to mitigate the platform noise based on the determined characteristics of the platform noise.

Logic may define one or more wake-up preambles suitable for high data rates for a wake-up radio (WUR) packet. Logic may define wake-up preamble with different counts of symbols. Logic may generate a wake-up preamble as two microsecond pulses of orthogonal frequency-division multiplexing (OFDM) symbols in a four megahertz (MHz) bandwidth. Logic may generate and receive a high data rate (HDR) WUR preamble or a low data rate (LDR) WUR preamble. The HDR preamble may signal a data rate of 250 kilobits per second and the LDR preamble may signal a data rate of 62.5 kilobits per second. The HDR preamble bit count may be twice a bit count of the LDR preamble. The HDR preamble may be 32 bits. The duration of transmission of the HDR may be 64 microseconds and duration of transmission of the LDR may be 128 microseconds.

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.
