Abstract: This disclosure describes systems, methods, and devices related to a trigger-based null data packet (NDP) for channel sounding system. A device may send a trigger frame to a group of station devices, the group of station devices including a first station device, the trigger frame indicating a high efficiency (HE) long training field (HE-LTF) mode and a guard interval duration. The device may identify a HE trigger-based (TB) null data packet (NDP) received from the first station device, the HE TB NDP including a first packet extension field, wherein the HE TB NDP is associated with the HE-LTF mode and the guard interval duration indicated in the trigger frame. The device may send a downlink NDP including a second packet extension field, a second HE-LTF mode, and a second guard interval duration. The device may determine channel state information based on HE TB NDP received from the first station device.

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: An interference-control based dynamic CCA scheme is described which will work in any compatible wireless system, including the 802.11 standards mentioned herein and in particular 802.11ac and 802.11ax. The interference control based dynamic CCA scheme can, for example, greatly improve overall wireless LAN system performance compared to other methods. The new scheme is based on interference control, by considering the possible interference to neighbouring devices, and improving overall system performance and inter-device “fairness” through this interference-based consideration technique.

Abstract: This disclosure describes systems, methods, and devices related to enhanced frame exchange. A device may generate a first subset of a plurality of fields, wherein the first subset is mandatory in a probe request frame. The device may generate a second subset of the plurality of fields, wherein the second subset is optional in the probe request frame regardless of capability information of the device. The device may generate the probe request frame comprising the first subset and the second subset. The device may cause to send the probe request frame to an access point (AP) device.

Abstract: This disclosure describes systems, methods, and devices related to passive location measurement in wireless communications. A device may perform a ranging measurement with a first device and a second device. The device may identify a first uplink (UL) location measurement report (LMR) received from the first device. The device may identify a second UL LMR received from the second device. The device may cause to send a first broadcast LMR comprising information associated with the ranging determination of the first device and the second device. The device may cause to send a second broadcast LMR comprising the measurement information carried in the first UL LMR and the second UL LMR.

Abstract: This disclosure describes systems, methods, and devices related to enhanced ranging. A device may initiate a ranging sequence by transmitting an NDPA frame followed by an I2R NDP frame. The device may receive a corresponding R2I NDP frame and an R2I LMR from a responding station. The device may repeat the ranging sequence for two or more iterations to collect multiple data sets. The device may process the R2I NDP frame and the R2I LMR to generate continuous ToA and ToD measurements for each iteration.

Abstract: This disclosure describes systems, methods, and devices related to enhanced low-density parity-check (LDPC) coding. A device may generate a frame comprising a data field, wherein the data field comprises a number of information bits. The device may calculate a required initial number of orthogonal frequency-division multiplexing (OFDM) symbols based on the number of information bits. The device may calculate an initial number of segments in a last OFDM symbol of the number of OFDM symbols. The device may calculate a number of data bits that can be filled within an initial number of OFDM symbols. The device may determine an LDPC codeword length based on the calculated number of data bits that can be filled. The device may cause to send the frame to one or more devices based on the LDPC codeword length.

Abstract: This disclosure describes systems, methods, and devices related to unequal modulation and coding scheme (unequal MCS). A device may decode user fields or first portions of unequal modulation and coding scheme (UEM) user fields from a first user specific field. The device may determine resource allocations, resource unit (RU) and multiple resource unit (MRU) allocations, based on the order of decoded user fields or the first portions of UEM user fields. The device may identify whether a user is a UEM user based on an indication in a first portion of a UEM user field or a new designed subfield, MCS type subfield, in a first user specific field. The device may decode a second user specific field to retrieve remaining portions of UEM user fields for UEM users to obtain the full set of MCSs.
