Abstract: Embodiments of a low-power wake-up radio (LP-WUR) are generally described herein. In some embodiments, a wireless device is set to a first state or a second state, wherein in the first state the wireless device is configured to receive wake-up (WU) packets, and wherein in the second state the wireless device is configured to not receive WU packets, wherein the wireless device comprises a WLAN radio and a low-power wake-up radio (LP-WUR).In some embodiments, the wireless device is configured to receive a wake-up packet, turn on the WLAN radio and turn off the LP-WUR. In some embodiments, the wireless device is configured to turn off the WLAN radio and turn on the LP-WUR for power conservation. In some embodiments, the wireless device turns off the WLAN radio and turns off the LP-WUR, and can periodically turn on the LP-WUR radio for extreme power saving.

Abstract: This disclosure describes systems, methods, and devices related to low power wake-up radio beacon signaling. An access point may determine timing information for the transmission of low power wake up radio beacons and send that timing information to a user device. An access point may then send low power wake up radio beacons based on that timing information to a user device, and a user device may receive the low power wake up radio beacons based on the timing information.

Abstract: Methods, devices, and systems for retransmission of wake-up signals from a first station to a second station over a wireless network are disclosed. In some aspects, a wake-up signal is encoded for transmission to the second station. While the first station is waiting for an acknowledgment of the wake-up signal from the second station, the second station may retransmit the wake up signal and/or encode a packet for transmission to a third station. In some aspects, whether the wake-up signal is retransmitted is based in part, on at least one of whether a number of timeout events for wake-up signals transmitted to the second station exceeds a maximum timeouts threshold, whether a number of wake-up signals transmitted to the second station exceeds a maximum wake-up signals threshold; or whether a maximum predetermined elapsed time since a first wake-up signal was transmitted to the second station is exceeded.

Abstract: A wireless communication device, a system, and a method. The device may use memory circuitry and processing circuitry to process a packet wirelessly transmitted to the STA from a serving AP. The packet may be configured according to a first wireless communication protocol from a serving AP, such as, for example, WLAN. The wireless communication device may further process a low modulation packet configured according to a second wireless communication protocol from a candidate access point, the low modulation packet being at a modulation rate lower than a lowest modulation rate for the first wireless communication protocol. The second wireless communication protocol may be the LP-WU radio communication protocol. The device may determine a received signal strength indicator (RSSI) value of the low modulation packet, and may further process a frame including information on an address or signature, such as a Service Set Identifier (SSID) for the serving AP corresponding to the candidate access point, the frame being from the serving access point, from the candidate access point, or from another wireless communication device. The device may then associate the RSSI value with the address of the candidate access point, and trigger transition of the device from the serving access point to the candidate access point based on the RSSI value and on the address of the candidate access point.

Abstract: Embodiments of service discovery via LP-WUR (low-power wake-up radio) are generally described herein, A wireless device receives, at a LP-WUR of the wireless device, a wake-up packet from a peer device. The wireless device decodes the wake-up packet to determine a service ID (identifier) and protocol support information. The wireless device determines that the wireless device is operable to provide a service identified by the service ID and implement a protocol identified by the protocol support information, the protocol comprising NAN (neighbor aware networking) or Wi-Fi direct. The wireless device wakes up a WLAN (wireless local area network) radio of the wireless device in response to determining that the wireless device is capable of providing the service and implementing the protocol.
