Methods and arrangements to support wake-up radio packet transmission

A non-transitory computer-readable medium, comprising instructions to communicate a wake-up radio packet, which when executed by a processor, cause the processor to perform operations to:

• generate, by a logic circuitry of a wake-up radio (WUR) of a first device, the WUR packet with a 4 megahertz (MHz) bandwidth, wherein the WUR packet comprises a high data rate (HDR) preamble followed by a medium access control (MAC) frame, the HDR preamble to indicate a rate of transmission of the MAC frame, the HDR preamble comprising 32 bits to transmit using 2 microsecond pulses of orthogonal frequency-division multiplexing (OFDM) symbols to signal a data rate of 250 kilobits per second;
• and
• cause transmission of the WUR packet.

An apparatus to communicate a wake-up radio (WUR) packet, the apparatus comprising:

• memory;
• and
• a logic circuitry to decode the WUR packet with a 4 megahertz (MHz) bandwidth, wherein the WUR packet comprises a high data rate (HDR) preamble followed by a medium access control (MAC) frame, the HDR preamble to indicate a rate of transmission of MAC frame, the HDR preamble comprising 32 bits to transmit using 2 microsecond pulses of orthogonal frequency-division multiplexing (OFDM) symbols to signal a data rate of 250 kilobits per second.
