Abstract: This disclosure describes systems, methods, and devices related to tone mapping for a high-efficiency (HE) trigger-based (TB) null data packet (NDP) feedback physical layer protocol data unit (PPDU). A device may identify a frame received from a second device. The device may determine, based on the frame, a resource unit allocated to the device, wherein the resource unit is associated with a 20 MHz sub-channel of a bandwidth. The device may determine, based on the resource unit and the bandwidth, tones associated with a HE short training field (HE-STF) of a HE TB NDP feedback PPDU. The device may send the HE TB NDP feedback PPDU to the second device in the 20 MHz sub-channel, wherein the HE TB NDP feedback PPDU includes the tones.

Abstract: Techniques and mechanisms for providing redundancy with multiple batteries of a backup power system. In an embodiment, switch circuits are each coupled between a power bus and a different respective one of the multiple batteries. Respective nodes of the switch circuits are each to couple to a different respective power sink, wherein power delivery to the power sinks is monitored. Based on the monitoring, the switch circuits are configured for a first battery to serve a substitute for a second battery. Configuring the switch circuits includes electrically decoupling the second battery from a first node, and electrically coupling the first battery to deliver power via both a power bus and the first node. In another embodiment, multiple backup units each include a respective battery and switch circuit, wherein respective controllers of the backup units intermittently communicate monitoring information via a data bus.

Abstract: This disclosure describes systems, methods, and devices related to an extreme high throughput (EHT) signaling structure. A device may establish a communication channel with one or more station devices (STAs). The device may generate an extreme high throughput signal field (EHT-SIG) of a header, wherein the EHT-SIG field comprises information associated with resource allocations (RUs). The device may generate a frame comprising the header. The device may assign a first RU to a first station device. The device may assign a second RU to the first station device, wherein the first RU or the second RU is an aggregation of a 26-tome RU and a neighboring RU. The device may cause to send the frame to the first station device.

Abstract: This disclosure describes systems, methods, and devices related to enhanced bandwidth selection for wireless devices. A device may generate a request frame with at least one of a first indication of a bandwidth for which a second device is to measure a first noise level or a second indication of a resource unit for which the second device is to measure a second noise level. The device may send the request frame to the second device. The device may identify a response frame received from the second device, the response frame having a third indication of the first noise level or the second noise level and a fourth indication of the bandwidth or the resource unit. The device may determine, based on the first noise level or the second noise level, a parameter associated with a subsequent frame to send to the second device.

Abstract: Embodiments of an access point (AP), station (STA) and method of communication are generally described herein. The STA may determine a portion of a channel occupied by an incumbent device. The STA may refrain from communication in a first subset of resource units (RUs) that overlap the portion of the channel occupied by the incumbent device. The STA may determine a combined RU that comprises two or more RUs of a second subset of RUs that do not overlap the portion of the channel occupied by the incumbent device. The STA may encode a physical layer convergence procedure protocol data unit (PPDU) for transmission in the combined RU. The PPDU may be encoded in accordance with joint coding across the RUs of the combined RU.

A device may send a first null data packet (NDP) to a second device, and identify a second NDP received from the second device. The device may identify a location measurement report (LMR) received from the second device, the LMR including a first channel response indicative of a first arrival time of the first NDP at the second device and a first phase shift associated with the first NDP. The device may generate a second channel response indicative of a second arrival time of the second NDP at the device and a second phase shift associated with the second NDP. The device may determine that the first channel response does not match the second channel response, and may identify an attempted attack.

Abstract: Embodiments of an Extremely High Throughput Station (EHT STA) (STA1) configured for operating in a next-generation (NG) wireless local area network (WLAN) are described herein. In some embodiments, the EHT STA encodes a common signal field (SIG) (Coex-SIG) of an EHT PPDU to include a TXOP duration field. The TXOP duration field is more than seven bits to indicate an actual TXOP duration of a transmission from the EHT STA comprising the EHT PPDU transmitted to a second station (STA2). Decoding the TXOP duration field of the EHT PPDU by a third-party station (STA4) causes the third-party station (STA4) to defer a transmission until after an end of the transmission from the second station (STA2).
