Abstract: Logic may generate a wake-up radio packet, wherein the wake-up radio packet comprises an on-off keying (OOK) signal, a sequence of a preamble of the wake-up radio packet to indicate a rate of transmission of one or more OOK orthogonal frequency-division multiplexing (OFDM) symbols of a medium access control (MAC) frame of the wake-up radio packet, wherein a duration of transmission of the preamble is 128 microseconds for a low data rate and a duration of transmission of the preamble is 64 microseconds for a low data rate. Logic may communicate the wake-up radio packet to a physical layer device to transmit OFDM symbols of an IEEE 802.11 preamble on a channel followed by OOK OFDM symbols of the wake-up radio packet on a sub-band of the channel. And logic may generate at least a second wake-up radio packet to transmit on a contiguous channel bandwidth with OOK OFDM symbols.

Abstract: The disclosure provides techniques for power control for communications under a Very Low Power (VLP) mode. A communication device includes: processing circuitry, to encode a message to be transmitted to a second communication device, to indicate a setpoint, wherein the setpoint is defined as a minimum power at which a packet is required to be transmitted under a set of packet parameters, such that the packet could be successfully received by the communication device; and a transceiver, to transmit the message to the second communication device, and receive the packet transmitted at a power determined based on the setpoint and a margin, from the second communication device, wherein the margin is determined based on a probability of measurement errors.

Abstract: Logic to initialize a scrambler. Logic to receive a portion of a first physical layer protocol data unit (PPDU) comprising a multi-user ready to send (MU-RTS) and first scrambler initialization bit sequence used to scramble the MU-RTS prior to transmission of the PPDU. Logic to determine a second scrambler initialization bit sequence in accordance with a pre-defined procedure. Logic to generate a medium access control (MAC) clear to send (CTS) frame to transmit in response to receipt of the MU-RTS. Logic to initialize a scrambler with the scrambler initialization bit sequence. Logic to generate a second PPDU comprising the CTS frame, the generation of the second PPDU to scramble the CTS frame with the scrambler after initialization. Logic to cause the transmission of the second PPDU in response to receipt of the MU-RTS. And logic to determine scrambler initialization bits having seven least significant bits are not all zeros.
