Abstract: A method includes obtaining input features based on network traffic received during a time window. The method also includes generating multiple network service type predictions about the network traffic during the time window using a machine learning (ML) classification system operating on the input features. The method also includes storing the multiple network service type predictions in different time steps in a first-in first-out (FIFO) buffer and generating decisions about a presence of each of multiple service types in the network traffic using a voting algorithm. The method also includes reducing fluctuations in the generated decisions using a logic-based stabilizer module to generate a final network service type decision.

Abstract: A method and apparatus for detecting network service types by grouping together applications that have similar latency requirement and data characteristics to form a service type. Machine learning algorithms may be used to detect the traffic pattern in the traffic stream by using features extracted from packet information and optionally additional sensor information. Subsequently, the output of the machine learning module may go through a post-processing process that may employ different techniques to use current prediction and past predictions to make a final decision about the network service type.

Abstract: Methods and apparatuses for enabling reuse, by a node in a basic service set (BSS), of a channel medium that is in use by devices of an overlapping BSS (OBSS) in a wireless local area network. A method of wireless communication performed by a first node includes the steps of obtaining, based on transmissions from other nodes in at least one of a BSS or an OBSS, network context information for a network environment around the first node, updating an OBSS packet detection (PD) threshold for spatial reuse (SR) based on the network context information, and performing, for a transmission to one of the other nodes in the BSS, an SR clear channel assessment (CCA) using the updated OBSS PD threshold for detection of packets transmitted by the nodes in the OBSS.

Abstract: A method and electronic device for radar-based face authentication anti-spoofing for determining access to the electronic device. The electronic device includes a radar transceiver and at least one processor. The at least one processor is configured to transmit, via the transceiver, a first set of signals, generate a channel impulse response (CIR) based on receipt of reflections of the first set of signals, detect a first CIR tap in the CIR, determine a selection of CIR data based on the detected first CIR tap, determine a profile matching metric based on comparison of the selection of CIR data to a set of predetermined reference signals, and determine whether to allow access to the electronic device based on comparison of the profile matching metric to a profile matching threshold.

Abstract: A method includes obtaining statistical information of incoming network traffic. The method also includes using a state machine to classify the incoming network traffic as a traffic pattern based on the statistical information. The method further includes using the traffic pattern to adapt one or more Target Wakeup Time (TWT) parameters to optimize power consumption of a Wi-Fi station. The traffic pattern includes at least one of bursty traffic, random traffic, and stable traffic.

Abstract: A method includes calibrating, at a wireless device, a wireless fidelity (Wi-Fi) chipset-level timer based on a time synchronization function (TSF) frame received from a Wi-Fi access point. The method also includes performing, at the wireless device, a coarse synchronization of a microcontroller-level or CPU-level timer based on the calibrated Wi-Fi chipset-level timer. The method further includes performing, at the wireless device, a fine synchronization of the microcontroller-level or CPU-level timer after the coarse synchronization. The fine synchronization is performed according to a first time scale measured in first time units and the coarse synchronization is performed according to a second time scale measured in second time units that are a multiple of the first time units.

Abstract: A mobile access point (AP) includes a first wireless transceiver configured to transmit and receive traffic with a first mobile station (STA), a second wireless transceiver configured to transmit and receive traffic with a gNB, and a processor operably coupled to the first wireless transceiver and the second wireless transceiver. The processor is configured to route traffic between the first mobile STA and the gNB, and determine, based on a traffic classification operation, a class of the traffic. The processor is further configured to establish, based on the class of the traffic, a Target Wake Time (TWT) agreement between the mobile AP and the first mobile STA. The TWT agreement permits the first wireless transceiver to doze. The processor is further configured to determine, based on the class of the traffic, a continuous mode discontinuous reception (CDRX) configuration for the second wireless transceiver.

Abstract: Methods and apparatuses for link recommendation for meeting QoS requirements. A method of wireless communication performed by an AP associated with an AP MLD, the method comprising: receiving an indication of quality of service (QoS) requirements from a non-AP MLD; determining whether an existing target wake time (TWT) or existing links are sufficient to meet QoS requirements; when the existing TWT or existing links are not sufficient to meet the QoS requirements, transmitting a message to the non-AP MLD indicating a need to negotiate additional TWT service periods (SPs) or to transition additional enabled links to an active mode or enable additional links with the AP MLD; and when the existing TWT or existing links are sufficient to meet the QoS requirements, scheduling uplink or downlink resources to meet the QoS requirements.
