  • Management and mitigation of narrowband interference
    Patent number: 10362584
    Abstract: A method performed by a transmitting station for assisting a receiving station in mitigating effects of a narrowband interference affecting the receiving station in a wireless communications network. The transmitting station determines (503) a likelihood of presence of the narrowband interference. When the likelihood of presence of the narrowband interference exceeds a threshold of the likelihood, the transmitting station sends (505) to the receiving station a recommendation to avoid smoothing of the channel estimates of the receiving station. The recommendation indicates a high likelihood of presence of the narrowband interference.

  • Asymmetric multi-destination traffic replication in overlay networks
    Patent number: 10326694
    Abstract: Presented herein are hybrid approaches to multi-destination traffic forwarding in overlay networks that can be used to facilitate interoperability between head-end-replication-support network devices (i.e., those that only use head-end-replication) and multicast-support network devices (i.e., those that only use native multicast). By generally using existing tunnel end-points (TEPs) supported functionality for sending multi-destination traffic and enhancing the TEPs to receive multi-destination traffic with the encapsulation scheme they do not natively support, the presented methods and systems minimize the required enhancements to achieve interoperability and circumvents any hard limitations that the end-point hardware may have. The present methods and systems may be used with legacy hardware that are commissioned or deployed as well as new hardware that are configured with legacy protocols.

  • Methods for coherent antenna switching in AoD positioning scheme
    Patent number: 10306413
    Abstract: Devices and methods of estimating the AoD of a STA are generally described. The STA receives comparison symbols from a first AP antenna. The comparison symbols are received prior to and after switching of transmitter chains from a first set of antennas to a second set of antennas. AoD symbols are received immediately after the comparison symbols. A phase and amplitude correction is determined based on a phase and amplitude change between the comparison symbols and the second AoD symbol corrected based thereon. The AoD is subsequently estimated based on the symbol measurements.

  • Consistent hashing for network traffic dispatching
    Patent number: 10298450
    Abstract: A method is provided that uses a consistent hashing technique to dispatch incoming packets in a stable system prior to adding of a node. The method uses a hash table and assigns hash buckets in the table to each network node. A set of fields in each incoming packet is hashed and is used to identify the corresponding hash bucket. The packets are then dispatched to the network nodes based on the nodes' hash buckets. During an observation period, the method identifies the ongoing sessions by creating a bit vector table that is used to identify the old and new sessions during a re-dispatching period. The method uses the consistent hashing method and the probabilistic method dispatch the incoming packets such that each packet that belongs to an old session is dispatched to the same old node that has been processing the other packets of the session.
