Abstract: This disclosure describes methods, apparatuses, and wireless stations related to waking up low power radios. In particular, a wireless station is disclosed that may identify a first management frame from a first wireless station a first management frame from a first wireless station. The wireless station may cause to allocate one or more group identifications (IDs) to the first wireless station. The wireless station may cause to generate a bitmap corresponding to the allocation of the one or more group IDs to the first wireless station. The wireless station may cause to send a second management frame to the first wireless station of one or more wireless stations, wherein the second management frame comprises the bitmap.

Abstract: This disclosure describes systems, methods, and devices related to allocating non-continuous resource units (RUs). A device may determine a non-continuous RU allocation for one or more devices in a 80 MHz bandwidth including four 20 MHz channels, the non-continuous RU allocation including disabled tones of a 20 MHz channel of the four 20 MHz channels, and the disabled tones being a subset of tones within the 20 MHz channel. The device may determine a high efficiency wireless frame comprising an indication of the non-continuous RU allocation. The device may send the high efficiency wireless frame to one or more multiple devices.

Abstract: This disclosure describes systems, and methods related to determining carrier frequency offset of a wireless communication channel based on a determined phase difference. In some embodiments, an access point is caused to receive one or more streams comprising one or more encoded long training field (LTF) symbols over the wireless communication channel from one or more user devices. The access point then determines a first phase of the wireless communication channel upon receipt of a first LTF symbol, and determines a second phase of the wireless communication channel upon receipt of a second LTF symbol. The access point next determines a phase difference between the first phase and the second phase. Based on the determined phase difference, the access point determines a carrier frequency offset of the wireless communication channel. Lastly, the access point modifies the wireless communication channel based at least in part on the determined CFO.

Abstract: This disclosure describes systems, methods, and devices related to high throughput (HT) control information. A device may determine a frame comprising HT control information. The device may determine to extend a size of the HT control information. The device may cause to generate a management or data frame for sending to a first station device of one or more station devices, the management or data frame comprising extended high throughput (HT) control information, define a new control identification (ID) associated with the extended HT control information, and cause to send the management or data frame to the first station device.

Abstract: The application relates to a preemption mechanism for wireless local area networks (WLANs), and in particular provides a method, including: broadcasting information about a Transmission Opportunity (TXOP) on a wireless channel, wherein the TXOP includes two or more transmission durations and a preemption period exists between any two neighboring transmission durations of the two or more transmission durations; and pausing communicating on the wireless channel during the preemption period to give opportunity for one or more stations (STAs) to preempt the wireless channel to transmit high priority traffic.

Abstract: Simultaneous dual band operation (2.4 and 5 GHz) is common in APs on the market today, and tri-band devices are expected in the market soon. Link aggregation can also be applicable to multiple air interfaces in the same band (for instance 2 independent IEEE 802.1 lac/ax air interfaces at 5 GHz on 2 different 80 MHz channels). One exemplary aspect provides technology that enables significantly higher throughput and/or higher reliability for two stations (STAs) or a STA and the access point (AP) when the devices support simultaneous multi-band operation.

Abstract: This disclosure describes systems, methods, and devices related to null data packet (NDP) frame format. A device may cause to send a null data packet announcement (NDPA) frame to a responding station device (RSTA). The device may cause to send a first sounding NDP frame comprising one or more fields formatted to support 2.4 gigahertz (GHz) and 5 GHz bands in a non-trigger-based ranging measurement with the RSTA. The device may identify after a passage of a short inter-frame space (SIFS) time a second NDP frame received from the RSTA. The device may identify a location measurement report frame from the RSTA.

Abstract: This disclosure describes systems, methods, and devices related to low latency preemption. A device may divide a first PPDU into a plurality of segmented PPDUs. The device may insert a plurality of time gaps between the plurality of segmented PPDUs, wherein the plurality of time gaps enable preemptive opportunities by a low latency transmitter. The device may identify a preemption request from a low latency transmitter of the one or more station devices during a first time gap between a first segmented PPDU and a second segmented PPDU. The device may preempt the second segmented PPDU based on a preemption bit in order to allow the low latency transmitter to transmit its low latency data.
