Abstract: This disclosure describes systems, methods, and devices related to an invalid location measurement report (LMR) indication. A device may identify a first null data packet (NDP) received from a first station device during, wherein the first NDP is used for channel sounding. The device may perform a time of arrival (ToA) calculation based on the NDP. The device may determine an invalid indication associated with the first NDP based on the ToA calculation. The device may generate an LMR comprising of the invalid measurement indication. The device may cause to send the LMR to the first 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.

Abstract: The disclosure provides some embodiments for securing long training field (LTF) sequence. A responding station (RSTA) configures a location management report (LMR) frame. The LMR frame is configured to include an LMR in respect of a previous measurement, and data to be used to generate a null data packet (NDP) for a current measurement that is to be performed following the previous measurement. The RSTA further encrypts the LMR frame using protected management frames (PMF) scheme, and transmits the encrypted LMR frame to an initiating station (ISTA) for generating an LTF sequence for the current measurement. In response to receiving an NDP announcement (NDPA) and an NDP for the current measurement from the ISTA, the RSTA generates an NDP for the current measurement based on the NDPA and the data using CCMP, and transmits the NDP to the ISTA.

Abstract: Methods, apparatuses, and computer readable media for tone plans and preambles for extremely high throughput (EHT) in a wireless network are disclosed. An apparatus of an EHT access point (AP) or EHT station (STA), where the apparatus includes processing circuitry configured to: encode a physical layer (PHY) protocol data unit (PPDU), the PPDU including a EHT preamble, the EHT preamble including a legacy preamble portion and a EHT preamble portion, the legacy preamble including a legacy short training field (L-SFT), a legacy long-training field (L-LTF), and a legacy signal field (L-SIG), the EHT preamble portion comprising an EHT short signal field (EHT S-SIG), the EHT S-SIG including a modulation and coding scheme (MCS) subfield indicating a MCS of a subsequent data portion. The PPDU may be transmitted on a distributed or contiguous resource unit (RU) allocation. The RU may be configured to not straddle two physical 20 MHz subchannels.

Abstract: This disclosure describes systems, methods, and devices related to extreme high throughput (EHT) data scrambler. A device may determine an extreme high throughput (EHT) data field of a frame to be scrambled using an EHT data scrambler. The device may determine to initialize the EHT data scrambler using an initialization seed, wherein the initialization seed has a size greater than seven bits. The device may generate scrambled data using the initialization seed. The device may cause to send the frame comprising the scrambled data to a first station device.

Abstract: Embodiments of an access point (AP), station (STA) and method of communication are generally described herein. The AP may be configurable to operate as a controlling AP of a multi-AP group. The controlling AP may establish the multi-AP group by: transmitting one or more messages to advertise the multi-AP group; and exchanging signaling with one or more of the other APs of the multi-AP group. The signaling may include at least one message related to one of the other APs joining the multi-AP group. The controlling AP may establish the multi-AP group to enable usage of AP Trigger Frames (AP TFs) for coordination of resources to be used for downlink transmissions of the APs of the multi-AP group.

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.
