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).

Abstract: Some demonstrative embodiments include apparatuses systems and/or methods of ranging measurement. For example, an apparatus may include circuitry and logic configured to cause a first wireless communication station (STA) to receive from a second STA a sounding transmission for a range measurement of a range between the first STA and the second STA; to determine a channel response estimation based on the sounding transmission from the second STA; to determine a timing value based on the channel response estimation; and to transmit a feedback message to the second STA, the feedback message including the timing value.

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.
