    Abstract: A wireless communication device includes a memory, and a processing circuitry coupled to the memory. The processing circuitry is to process a wake-up radio (WUR) frame transmitted by an Access Point (AP), the WUR frame comprising a medium access control (MAC) header and a frame body, the MAC header comprising a Frame Control field, an Address field, and a Type Dependent (TD) Control field, wherein the Frame Control field comprises a Type field; determine, based on a value of the Type field, that the WUR frame is a WUR Discovery frame; determine an identifier (ID) of the AP from the WUR Discovery frame; and in response to a determination that the WUR frame is a WUR Discovery frame, cause a Primary Connectivity Radio (PCR) corresponding to the wireless communication device to communicate with the AP based on the WUR Discovery frame.

    Abstract: A device, a system, and a method. The device is configured to be part of a first wireless apparatus, and comprises a memory, and processing circuitry coupled to the memory and including logic to cause the first wireless apparatus to: perform a WUR Mode setup frame exchange with a Primary Connectivity Radio (PCR) of a second wireless apparatus; establish a Wake-Up Radio (WUR) Mode operation with the second wireless apparatus based on the frame exchange; transmit a Wake-Up Radio (WUR) Teardown Frame to the PCR of the second wireless apparatus, the WUR Mode Teardown frame including information to cause a teardown of the WUR Mode operation with the second wireless apparatus; and process an acknowledgment message (ACK) from the second wireless apparatus to tear down the WUR Mode operation with the second wireless apparatus.

    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: This disclosure describes systems, methods, and devices related to wake-up radio (WUR) advertisement channels. A device may include a wake-up receiver (WURx) and a primary connectivity radio. The device may determine a wake-up radio (WUR) discovery subchannel for WUR advertisement. The WUR discovery subchannel may be associated with a channel of a frequency band. The device may generate a WUR discovery frame comprising a WUR advertisement. The device may transmit, by the WURx, the WUR discovery frame to a second device using the WUR discovery subchannel. The device may identify a response from the second device indicating an acknowledgment of the WUR discovery frame.

    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.
