Abstract: For example, an apparatus may include a segment parser to parse scrambled data bits of a PPDU into a first plurality of data bits and a second plurality of data bits, the PPDU to be transmitted in an OFDM transmission over an aggregated bandwidth comprising a first channel in a first frequency band and a second channel in a second frequency band; a first baseband processing block to encode and modulate the first plurality of data bits according to a first OFDM MCS for transmission over the first channel in the first frequency band; and a second baseband block to encode and modulate the second plurality of data bits according to a second OFDM MCS for transmission over the second channel in the second frequency band.

Abstract: A wireless communication device, method and system. The device includes a memory, and a processing circuitry coupled to the memory. The processing circuitry is to: decode at least one signal field portion of a signal field of a Physical Layer Convergence Protocol (PLCP) Data Unit (PPDU) received over a bonded channel, the bonded channel comprising a plurality of subchannels including a punctured subchannel, the signal field portion on at least one unpunctured subchannel of the plurality of subchannels; determine, from the at least one signal field portion, information on a resource allocation for the device, the resource allocation indicating at least one resource unit (RU) used in a data field of the PPDU for the device; and decode a data field portion of the data field of the PPDU, the data field portion received on a part of the punctured subchannel based on the resource allocation.

Abstract: Methods, apparatuses, and computer readable media for a common preamble for wireless local-area networks (WLANs). An apparatus of an access point (AP) or station (STA) comprising processing circuitry configured to encode an AP trigger frame that includes a resource allocation for other APs to transmit trigger frames to perform an uplink or downlink multi-user transmission with stations (STAs). The resource allocation includes information so that the transmissions are coordinated at the physical level to lessen interference among the APs and the stations. The processing is configured to encode a trigger frame for multi-AP request-to-send (RTS), the multi-AP trigger frame comprising for each of a plurality of APs, the trigger frame indicating that each of a plurality of APs are to transmit a physical (PHY) protocol data unit (PPDU) comprising a request-to-send (RTS) or multi-user (MU) RTS (MU-RTS).

Abstract: Embodiments of an Extremely High Throughput Station (EHT STA) (STA1) configured for operating in a next-generation (NG) wireless local area network (WLAN) are described herein. In some embodiments, the EHT STA encodes a common signal field (SIG) (Coex-SIG) of an EHT PPDU to include a TXOP duration field. The TXOP duration field is more than seven bits to indicate an actual TXOP duration of a transmission from the EHT STA comprising the EHT PPDU transmitted to a second station (STA2). Decoding the TXOP duration field of the EHT PPDU by a third-party station (STA4) causes the third-party station (STA4) to defer a transmission until after an end of the transmission from the second station (STA2).

Abstract: An exemplary variable geometry turbine includes a turbine wheel; a variable geometry assembly that includes a rotatable control ring that has a slot and a plurality of vanes where each vane has a post pivotably controlled by rotation of the control ring and where adjacent vanes define nozzles to direct exhaust gas to the turbine wheel; a crankshaft that has a pin for receipt by the slot of the control ring where rotation of the crankshaft rotates the control ring; and a center housing that includes a rotatable stop fixed to the crankshaft and having a close stop surface, a secure component and a translatable shaft where the translatable shaft comprises an engagement mechanism to engage the rotatable stop; where translation of the shaft causes rotation of the crankshaft and where the close stop surface establishes a contact with the secure component to limit rotation of the crankshaft and to establish a closed limit for the vanes. Various other exemplary methods, devices, systems, etc., are also disclosed.

Abstract: A turbocharger having a variable turbine nozzle that includes an array of vanes whose setting angle is adjustable by rotation of a crank shaft coupled with a unison ring that pivots the vanes. The crank shaft is rotated by an actuation system made up of a piston contained in a bore formed in the center housing, and a hydraulic system for supplying pressurized hydraulic fluid to the bore selectively on one side or an opposite side of the piston for causing the piston to move in one direction or the other. The piston is connected to the crank shaft by a mechanical linkage that converts reciprocating movement of the piston to rotational movement of the crank shaft. A spring is arranged between the piston and a surface of the bore and continuously exerts a spring force on the piston toward the fully open position of the piston.
