Abstract: Embodiments of fast steering timing and resource allocation are generally described herein. In some embodiments, a non-access point station (STA) decodes a fast steering timing signaling element (STSE) at a Narrow Band Control sub-Channel (NB-C-CH) and from an allocator device, the STSE indicating at least fast steering timing information, an identified Narrow Band Service sub-Channel (NB-S-CH), resource allocation information for the identified NB-S-CH, and connectivity information for the identified NB-S-CH, the identified NB-S-CH being selected from a plurality of NB-S-CHs. The STA exchanges packets in the NB-S-CH according to the resource allocation information and the connectivity information and based on the fast steering timing information. The STA encodes or decodes data associated with the exchanged packets.

Abstract: Embodiments of an access point (AP), station (STA) and method of communication are generally described herein. The AP may include a used basic service set (BSS) color in a downlink physical layer convergence procedure protocol, data unit (PPDU). The used BSS color may indicate communication between the AP and associated STAs. The AP may detect another PPDU from an STA that is un associated with the AP. If a header portion of the detected PPDU includes the used BSS color, the AP may: determine an alternate BSS color, and transmit a color switch announcement (CSA) element that indicates the alternate BSS color. The CSA element may be configurable to further indicate whether the AP and the associated STAs are to switch, from the operating channel to an alternate channel for the communication.

Abstract: An apparatus for implementing power control for a radio device that has multiple radio transceivers operating in different bands, including sub-bands of a single frequency band. The device implements a power control protocol for communications between the device and a similar peer device. The device sets-up the power control protocol by generating a request to use one of the multiple bands to signal power control operations, and to use another one of the multiple bands to transfer data between the device and the peer device. The device sends the request to the peer device and receives a response. Based on the response, the device identifies a control channel band and a data channel band from among the multiple bands.

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: 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.
