Abstract: 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.

Abstract: 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.

Abstract: This disclosure describes systems, methods, and devices related to delay indication. A device may identify a first frame received from a first station device, wherein the first frame comprises a first transition delay field, wherein the first transition delay field comprises a first transition delay value associated with a power state transition. The device may determine a wake up receiver (WUR) frame comprising an indication for waking up the main radio of the first station device. The device may cause to send the WUR frame to the first station device based on the first transition delay value.

Abstract: For example, a wireless communication device may be configured to determine a Resource Unit (RU) allocation of a plurality of RUs to a plurality of wireless communication stations (STAs), respectively, the RU allocation to allocate to a STA of the plurality of STAs an RU of the plurality of RUs, wherein an RU size of the RU allocated to the STA is based at least on a traffic rate parameter, which is dependent on a traffic rate of Downlink (DL) traffic for the STA; and to transmit a Multi-User (MU) DL Orthogonal-Frequency-Division-Multiple-Access (OFDMA) Physical-layer Protocol Data Unit (PPDU) to the plurality of STAs according to the RU allocation.

Abstract: This disclosure describes systems, methods, and devices related to service set compression. A device may determine a wake-up frame comprising one or more fields, wherein the one or more fields indicate an action to be taken on a receiving device. The device may determine an identifier to be indicated in the wake-up frame. The device may determine a size of the identifier. The device may cause to compress the identifier forming a compressed output, wherein the identifier is compressed by applying a cyclic redundancy code (CRC) computation. The device may identify a portion of the compressed output. The device may cause to send the wake-up frame to a receiving device, wherein the wake-up frame comprises the portion of the compressed output based on the size of the identifier.

Abstract: 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 an on-off keying (OOK) signal. Logic may generate and receive a wake-up preamble that signals a high data transmission rate with respect to data rates defined for WUR packet transmissions. Logic may generate or receive a preamble that signals a rate of transmission of the WUR packet as 250 kilobits per second. Logic may transmit or receive bits of the wake-up preamble as two microsecond orthogonal frequency-division multiplexing (OFDM) based pulses, wherein each two microsecond OFDM based pulse is based on a 32-point Fast Fourier Transform (FFT) in a 20 Megahertz (MHz) bandwidth, with a subcarrier spacing of 625 Kilohertz (KHz) to produce six subcarriers in a four MHz bandwidth.
