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: The application relates to an apparatus and method used in Wireless Local Area Networks (WLANs). The apparatus includes: a Radio Frequency (RF) interface; and processor circuitry coupled with the RF interface and configured to: generate an Extremely High Throughput (EHT) Physical Protocol Data Unit (PPDU); and provide the EHT PPDU to the RF interface for transmitting on a transmission bandwidth, wherein any of distributed Resource Units (dRUs) for transmitting a data portion of the EHT PPDU is associated with a whole or part of an EHT-Short Training Field (STF) sequence constituting the EHT PPDU, and any of the dRUs is a resource unit, subcarriers of which are distributed across one or more frequency sub-blocks within the transmission bandwidth for transmitting the EHT PPDU.

Abstract: This disclosure describes systems, methods, and devices related to distributed resource unit (dRU) pilot tones. A device may determine a plurality of pilot tones across a first frequency resource. The device may adjust the plurality of pilot tones with a first pilot offset adjustment parameter. The device may cause to send a frame to a first station device using the adjusted plurality of pilot tones.
