Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for low-latency communications in wireless networks. In some implementations, a wireless station (STA) may transmit a data session request to a root access point (AP) in a wireless network responsive to activating an application associated with latency restricted (LR) data traffic. In some aspects, the data session request may indicate one or more preferred channels to carry the LR data traffic. In some other aspects, the data session request may indicate one or more preferred times to exchange the LR data traffic. In some implementations, the root AP may establish an LR data path with the STA based on the preferred time or frequency resources indicated in the data session request. The LR data path may include time or frequency resources that are reserved for LR data traffic between the root AP and the STA.

Abstract: The present disclosure relates to a liquid-cooling radiating pipe and a vacuum interrupter with a built-in liquid-cooling radiating pipe, belonging to the field of vacuum circuit breakers. Based on an original structure of an vacuum interrupter, a liquid-cooling radiating pipe of a Tesla valve structure is arranged in a conductive rod of the vacuum interrupter with the built-in liquid-cooling radiating pipe, and liquid metal is used as a circulating coolant in the liquid-cooling radiating pipe, and by using the self-circulating flow of the liquid metal in the pipeline, the capacity of the conductive rod to dissipate heat to the outside is significantly increased, and the problem of excessive internal temperature rise of a vacuum circuit breaker is effectively solved.

Abstract: Methods, systems, and devices for wireless communication are described. For example, the described techniques provide for a first device (e.g., a cellular modem or user equipment (UE)) mapping quality of service flows of a first radio access technology (e.g., cellular) to service classes of a second RAT (e.g., Wi-Fi). The first device may communicate mapping information that indicates the mapping to a second network device (e.g., a router). The first device and the second device may communicate various packets via the quality of service flows and the service classes.

Abstract: Aspects of the present disclosure allow for improving E2E mesh throughput by applying transmission (TX) biasing on the Wi-Fi mesh backhaul. Aspects of the disclosure are directed to solutions for reducing traffic load in Wi-Fi mesh networks by applying TX biasing on the Wi-Fi mesh backhaul. Certain aspects are directed to selectively transmitting or preventing transmission of data over the first backhaul link to the first MLD based at least in part on a fronthaul airtime utilization, a first backhaul airtime utilization, or a second backhaul airtime utilization. Doing so allows a root access point or a network controller to apply TX biasing between multi-link operation links towards each repeater so that traffic load on a backhaul-link would not overly occupy the front-haul link because of common channel use by selectively transmitting or preventing transmission of data on the backhaul links.

Abstract: An identity authentication method is disclosed in embodiments of the present application. When a requester and an authentication access controller perform identity authentication using an authentication mechanism of a pre-shared key, the identity information of entities is transmitted in the form of ciphertext, thereby preventing the identity information of the entities from being exposed during the transmission, so that attackers cannot obtain private or sensitive information. The mutual or unilateral identity authentication between the authentication access controller and the requester is achieved while ensuring the confidentiality of the entity identity and related information, thereby laying a foundation for ensuring that the user accessing the network is legitimate and/or the network accessed by the user is legitimate.

Certain aspects are directed to obtaining load information from each wireless device of a set of wireless devices, the load information being indicative of resource availability for each band available to each wireless device of the set. In some examples, the disclosure is directed to identifying a first band and a first wireless device of the set of wireless devices associated with the first band based on the first band having a highest level of traffic among bands available to the set of wireless devices.

The first Multi-AP device receives, from the second Multi-AP device over the first communication link, a DPP Configuration Response Message indicating MLO association information responsive to the indicated MLO capabilities, and establishes a backhaul path with a third Multi-AP device, configured as a second Multi-AP Agent, on the first communication link and one or more second communication links according to the MLO association information.

Abstract: Methods, systems, and devices for wireless communications are described. In some wireless communications systems, a wireless device may buffer uplink communications. However, such approaches may be improved. An access point (AP) may receive, from a station, uplink traffic of a traffic flow for forwarding to a backhaul network via a backhaul link. The AP may monitor a buffer of the AP to determine that a quantity of buffered uplink traffic received from the station exceeds a buffer quota, the buffer quota set for the traffic flow based on a traffic throughput capacity of the backhaul link and a throughput parameter for the traffic flow. The AP may modify, based on the quantity of buffered uplink traffic exceeding the buffer quota, an uplink communication scheme to reduce the quantity of uplink traffic from the station.

Abstract: Techniques related to wireless communication are disclosed. Some aspects of the disclosure relate to devices and methods for improving a quality of service (QoS) by reporting near-real-time feedback relating to a delay experienced by packets queued for transmission, and dynamically scheduling a wireless station to transmit and meet its QoS. A wireless station (STA) obtains one or more packets for transmission, the packets being associated with a delay condition. The STA outputs for transmission a delay status report that includes information relating to the delay condition associated with the one or more packets. In response, the STA obtains a resource allocation for transmission of the one or more packets according to the information relating to the delay condition. Other aspects, embodiments, and features are also claimed and described.

The LR data path may include time or frequency resources that are reserved for LR data traffic between the root AP and the STA.

Abstract: This disclosure provides systems, methods and apparatus for synchronous channel access control of a wireless system. In some aspects, a device may use a TWT session to communicate with a second device during one or more TWT service periods. Uplink and downlink communications may be coordinated to both be in a TWT service period to allow a device to enter a low power mode outside of the TWT service period. The TWT session, including the service periods, may be configured and managed by the device or the second device to ensure the communications associated with an XR experience between the devices (such as pose data frames or tracking frames provided as uplink data and video data frames provided as downlink data) meet latency requirements or other requirements for the XR experience. Use of TWT service periods allows other devices to use the wireless medium outside of the TWT service periods.

Abstract: This disclosure provides systems, devices, apparatus and methods, including computer programs encoded on storage media, for managing access in a wireless local area network (WLAN) to support the quality of service (QoS) associated with a service of a wireless communication system. In one aspect, an access device may create a traffic flow between a station (STA) of the WLAN and Na network slice of the wireless communication system. The access device (such as a 5G customer premises equipment (5G-CPE)) may route traffic between the network slice and the STA based on the QoS associated with the network slice. Thus, in some implementations, the QoS for the network slice can be extended into the WLAN.

Abstract: This disclosure includes a multi-link device (MLD) transmitting a frame on a first communication link associated with a first device of the MLD, the frame carrying a plurality of addresses of a respective plurality of peer devices associated with a mesh basis service set (MBSS), each of the plurality of addresses associated with one of a per-link address of the first communication link of the MLD or a medium access control (MAC) address of the MLD. In some instances, the addresses include first and second addresses indicating respective receiver and transmitter addressees of a peering instance, and include third and fourth addresses indicating respective MBSS egress and MBSS ingress points of the peering instance. The first and second addresses are associated with the per-link address of the first communication link, and the third and fourth addresses are associated with the MLD MAC address.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for adjusting a packet duration for triggered uplink (UL) transmissions to an access point (AP) from one or more stations (STAs). In one aspect, the AP may estimate an amount of data that a STA has queued for UL transmission and select the packet duration based on the estimated amount of queued UL data. The AP may transmit a trigger frame that solicits UL data from the STA and indicates the selected packet duration. In response, the AP may receive an UL packet from the STA and determine an amount of UL data queued in the STA based on the UL packet. In some implementations, the AP may selectively adjust the packet duration for UL transmissions based on the UL packet, the determined amount of UL data queued in the STA, or both.

Abstract: Systems and methods for selectively enabling multi-user (MU) communications are disclosed. In some implementations, an access point (AP) obtains packets associated with a traffic flow, and obtains at least one of service-level agreement (SLA) parameters associated with the traffic flow, attributes of the traffic flow, or network parameters associated with a basic service set (BSS) that includes the AP. The AP provides an indication of whether the traffic flow is suitable for transmission as a single-user (SU) multiple-input multiple output (MIMO) (SU-MIMO) communication, as an MU-MIMO communication, as an orthogonal frequency division multiple access (OFDMA) communication, or as a partial bandwidth (BW) MU-MIMO communication to a WLAN subsystem of the AP, the indication being based on one or more of the SLA parameters, the traffic flow attributes, or the network parameters. The AP initiates transmission of the one or more packets based on the indication.

Abstract: This disclosure provides methods, devices and systems for provisioning resources for wireless communications. Some implementations more specifically relate to provisioning such resources based on a mapping of wireless communication devices to a number of time sectors that occur periodically and do not overlap other time sectors. In some aspects, each wireless stations (STAs) in a basic service set (BSS) may be mapped to a respective time sector based on attributes associated with the BSS so that communications between a STA and its associated access point (AP) can only occur within the respective time sector(s) to which the STA is mapped. In some other aspects, each AP in a multi-AP environment may be mapped to a respective time sector based on attributes associated with the multi-AP environment so that communications between an AP and its associated STAs can only occur within the respective time sector(s) to which the AP is mapped.
