摘要： 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.

摘要： An access point (AP) configured for multi-AP coordinated beamforming (CBF) and multi-AP joint transmission (JT) in an Extremely High Throughput (EHT) wireless local area network (WLAN), when operating as a master AP (AP1) in a multi-AP network, is configured to encode a null data packet announcement (NDPA) frame for multi-AP channel sounding. The NDPA is configured for transmission to a second AP (AP2) and a plurality of stations (STAs) of an EHT group. The NDPA may be encoded to have an information field indicating whether a sounding sequence type is for JT channel sounding or CBF channel sounding. The NDPA may further be encoded to include fields identifying the APs participating in the channel sounding. In these embodiments, the channel sounding sequence for JT can be reused for the channel sounding on CBF.

摘要： This disclosure describes systems, methods, and devices related to long packet extension signaling. A device may calculate a residual value based on a duration of a packet extension, a transmit time, and a signal extension time. The device may generate one or more data symbols of a frame to be transmitted to a station device (STA). The device may compare the residual value to a duration of a first data symbol of the one or more data symbols. The device may include a packet extension dis-ambiguity value to the frame based on the comparison. The device may cause to send the frame to the STA.

摘要： Methods, apparatuses, and computer readable media for report identification and power control for ranging in a wireless network are disclosed. An apparatus of a responding station (RSTA) is disclosed, where the apparatus comprises processing circuitry configured to perform ranging with a initiating stations (ISTAs) and maintain a separate sounding dialogue token for each of the ISTAs and transmit a corresponding sounding dialogue token for a ISTA in a trigger frame for ranging and sounding or a null data packet announcement (NDPA) frame, and in a responding to initiating location measurement report. Apparatuses of RSTAs and ISTAS are disclosed that perform power control management during non-trigger-based ranging.

摘要： For example, an apparatus may include logic and circuitry configured to cause a non Access Point (AP) (non-AP) station (STA) to identify at least one STA-blocked frequency bandwidth (BW) to be blocked for communication between the non-AP STA and an AP in a wireless communication frequency channel. For example, the non-AP STA may be configured to transmit a STA-initiated block request to the AP. For example, the STA-initiated block request may be configured to indicate a request from the non-AP STA to the AP to block the STA-blocked frequency BW for the communication between the non-AP STA and the AP.

摘要： The embodiments herein relate to Low Density Parity Check (LDPC) codes, their corresponding matrices, and with an LDPC decoder architecture used to decode those codes. Embodiments herein relate to methods to generate a set of LDPC codes (typically of different rates) that share their wires as much as possible and therefore reduce the silicon area and ease the routing.
