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 feedback for secure mode wireless communications. 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: This disclosure describes systems, methods, and devices related to codeword-based acknowledgments in Wi-Fi. A device may generate low-density parity-check (LDPC) codewords, each having a same length; generate a first physical layer (PHY) protocol data unit (PPDU) including the LDPC codewords; transmit the first PPDU to a second device; identify an acknowledgment received from the second device, the acknowledgment including a bitmap indicating that a first LDPC codeword of the LDPC codewords was not received by the second device; generate, based on the bitmap, a second PPDU including the first LDPC codeword; and transmit the second PPDU to the second device.

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.
