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.

Abstract: This disclosure describes systems, methods, and devices related to unequal MCS indication. A device may extract Resource unit (RU) or multi-RU (M-RU) allocation through one or more fields of a received frame from an associated access point (AP). A device may extract MCS information through MCS subfield of a User field of a User Specific Field in EHT-SIG. The device may extract spatial streams information through a spatial streams subfield of the User field of the User Specific Field in EHT-SIG. The device may determine one or more MCS indications based on the MCS information, RU or MRU allocation, and spatial streams information, determine its MCS indication.

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: Methods and apparatus are described for ultrasound transmission. A bit packet is created from received data. A cyclic redundancy check (CRC) is added to the bit packet based on the input data. The bit packet is encoded with forward error correction. The encoded bit packet is block interleaved to create a bit stream. The bit stream is converted into symbols. Each symbol is mapped to a dual tone multi frequency (DTMF). A first audio buffer based upon the DTMF is created. The audio buffer is provided for output.

Abstract: This disclosure describes systems, methods, and devices related to dynamic channel bonding and multi-band aggregation. A device may determine a plurality of aggregated medium access control (MAC) protocol data unit (A-MPDU) subframes to send to a station device including a first A-MPDU subframe and a second A-MPDU subframe. The device may determine a quiet period between the first A-MPDU subframe and the second A-MPDU subframe. The device may cause to send the plurality of A-MPDU subframes to the station device on a first channel. The device may determine a status of a second channel during the quiet period. The device may cause to send the second A-MPDU subframe to the station device using a multi-band transmission on the first channel and the second channel.

Abstract: This disclosure describes systems, methods, and devices related to extremely high throughput (EHT) trigger based (TB) preamble. A device may receive a trigger frame from an associated access point (AP), wherein the trigger frame comprises one or more resource unit (RU) bandwidths (BWs) allocated to the device. The device may generate an EHT physical layer protocol data unit (PPDU) based on receiving the trigger frame from the access point, wherein the PPDU comprises an EHT preamble that includes a signaling (U-SIG) field. The device may encode the U-SIG field with an indication of one or more resource unit (RU) bandwidth (BW) allocations to be used for sending the PPDU to the AP, wherein the indication is a value associated with a first option of one or more options of selectable RU BWs. The device may cause to send the PPDU to the AP and an uplink data transmission direction.
