Abstract: The application relates to ultra-low latency data transmission in Wireless Local Area Networks (WLANs). An apparatus used in a non-Access Point Station (non-AP STA), includes processor circuitry configured to cause the non-AP STA to, when there is urgent data that must be transmitted in uplink without waiting for a scheduled slot: generate a Protocol Data Unit (PDU) from the urgent data; and transmit the PDU on a resource unit pre-assigned for urgent transmission, wherein the resource unit is multiplexed for uplink transmission from multiple non-AP STAs.

Abstract: Logic to manage multiple link operations for more than one access point (AP) stations (STAs), wherein the more than one AP STAs include a control AP STA and a managed AP STA. Logic to associate, via the control AP STA, a first STA of a non-AP multi-link device (MLD) with the control AP STA to establish a control link and a second STA of the non-AP MLD with the managed AP to establish a managed link. Logic to cause transmission of a management frame, by the control AP STA, via the control link to establish a first TWT SP on the managed link during a first time interval. And logic to manage multiple link operations for more than one non-AP STAs, wherein the more than one non-AP STAs include a control STA and a managed STA.

Abstract: This disclosure describes methods, apparatuses, and wireless stations related to waking up low power radios. In particular, a wireless station is disclosed that may identify a first management frame from a first wireless station a first management frame from a first wireless station. The wireless station may cause to allocate one or more group identifications (IDs) to the first wireless station. The wireless station may cause to generate a bitmap corresponding to the allocation of the one or more group IDs to the first wireless station. The wireless station may cause to send a second management frame to the first wireless station of one or more wireless stations, wherein the second management frame comprises the bitmap.

Abstract: This disclosure describes systems, methods, and devices related to basic service set (BSS) information spreading indication. A device may determine one or more collocated access points (APs). The device may determine a target beacon transmission time (TBTT) associated with a beacon interval. The device may determine a first beacon frame comprising a first multiple basic service set identification (BSSID) element. The device may determine a second beacon frame comprising a second multiple BSSID element. The device may determine a time period associated with the first beacon frame and the second beacon frame. The device may cause to send the first beacon frame at a first time to one or more station devices. The device may cause to send the second beacon frame at a second time to the one or more station devices.

Abstract: The application relates to a preemption mechanism for wireless local area networks (WLANs), and in particular provides a method, including: broadcasting information about a Transmission Opportunity (TXOP) on a wireless channel, wherein the TXOP includes two or more transmission durations and a preemption period exists between any two neighboring transmission durations of the two or more transmission durations; and pausing communicating on the wireless channel during the preemption period to give opportunity for one or more stations (STAs) to preempt the wireless channel to transmit high priority traffic.

Abstract: Some demonstrative embodiments include apparatuses systems and/or methods of ranging measurement. For example, an apparatus may include circuitry and logic configured to cause a first wireless communication station (STA) to receive from a second STA a sounding transmission for a range measurement of a range between the first STA and the second STA; to determine a channel response estimation based on the sounding transmission from the second STA; to determine a timing value based on the channel response estimation; and to transmit a feedback message to the second STA, the feedback message including the timing value.

Abstract: This disclosure describes systems, and methods related to signal classification in a wireless communication network. A first computing device comprising one or more processors and one or more transceiver component may receive a signal transmission packet comprising a physical layer (PHY) preamble. The first computing device may identify within the PHY preamble, one or more signal (SIG) fields, wherein at least one of the one or more SIG fields includes at least a length field indicating a length of the signal transmission packet. The first computing device may determine based at least in part on the length field, that the signal transmission packet is associated with a predetermined communication standard utilized to transmit the signal transmission packet. The first computing device may decode the signal transmission packet based at least in part on the determination that the signal transmission packet is associated with the predetermined communication standard.

The device may cause to send the beacon frame to a second device and a third device. The device may cause to send first scheduling information to allocate a slot for receiving a first transmission from the second device. The device may determine a service period for additional slots for receiving a second transmission from the third device. The device may cause to send second scheduling information to allocate the additional slots. A device may receive a data frame including routing information for frame forwarding. The device may decode the routing information for a first preamble. The device may determine that the first preamble matches a second preamble. The device may cause to send the routing information to a second device while receiving the data frame.
