Timing improvements for wireless communications systems
Non-terrestrial networks (NTNs) may establish uplink (UL) and downlink (DL) radio frame timing structures to efficiently account for propagation delay and propagation delay variation associated with communications in the NTN. NTNs may manage (synchronize) radio frame timing structures of base stations (e.g., satellites) and user equipment (UEs) in the NTN. Further, UEs may determine timing advance (TA) values to be applied to UL transmissions based on their respective scheduling offset (e.g., offset in UL and DL radio frame timing structures), as well as based on propagation delay or round trip time (RTT). As such, served UEs may determine UL timing such that UL transmissions from the UEs to a satellite arrives at the satellite in a time synchronized manner. In other cases, a satellite may determine UL timing, based on reception timing, such that various UEs in the NTN may implement uniform UL and DL radio frame timing structures. |

Multi-SSID hidden wireless network
An access point provides a hidden wireless network that is configured with a set of SSIDs so that the hidden network is discoverable with multiple different SSIDs. Based on detection of a probe request frame which indicates an SSID from a device, the access point determines if the SSID for which network availability is requested matches one of the SSIDs in the set.

Devices connected to the hidden network may have initiated the establishment of the connection with a different SSIDs despite the hidden network being a single wireless network. Scaling the number of supported SSIDs therefore does not impact the frequency with which the access point transmits beacon frames for the hidden network. |

Deep learning to detect abusive sequences of user activity in online network
In an example embodiment, a deep learning algorithm is introduced that operates directly on a raw sequence of user activity in an online network. This allows the system to scalably leverage more of the available signal hidden in the data and stop adversarial attacks more efficiently than other machine-learned models.

This eliminates the need for human curation of features. Then, the standardized request paths are standardized to integers based on the frequency of that request path across all users. This allows information about how common a given type of request is to be provided to the machine-learned model. The integer array is the activity sequence that is fed into the deep learning algorithm. |

In some embodiments, the dedicated kernel threads execute on dedicated CPU cores (e.g., one kernel thread per CPU core) to proactively poll physical NICs (PNICs) of the host computer and virtual NICs (VNICs) of the machines (e.g., VMs), and to perform packet processing operations on packets received by the host and packets transmitted by the machines. In some embodiments, each PNIC or VNIC is associated with one dedicated kernel thread, in order to avoid synchronization issues between the kernel threads. In the discussion below, these kernel threads are referred to as fast-path packet processing threads or as logical cores, or Lcores, and the physical and virtual NICs that are polled by the Lcores are referred to as polled network devices. In some embodiments, one Lcore can process multiple polled network devices.
