  • Patent number: 10645030
    Abstract: A processor may apply data blocks of a training data set to a pattern matching algorithm to identify whether the data blocks match a pattern, determine points of divergence between the data blocks and the pattern, count a number of times that each of a plurality of positions in the pattern is determined to be a point of divergence, and determine a position with a highest count of a number of times that the position is determined to be a point of divergence. The processor may further receive an incoming data block, compare a data value at the position in the pattern with the highest count to a data value at a corresponding position in the incoming data block, and determine a mismatch when the data value at the position in the pattern and the data value at the corresponding position in the incoming data block are different.

  • Patent number: 10609682
    Abstract: The disclosure provides a method in a User Equipment (UE) and a base station for dynamic scheduling. The UE receives first information for determining X1 candidate resources and monitors second information that may occupy one of the X1 candidate resources. A first candidate resource is one of the X1 candidate resources. The first candidate resource includes a first Resource Element (RE) subset and a corresponding second RE subset. A time-frequency resource occupied by the second RE subset is related to a time-frequency resource occupied by the first RE subset. If the first candidate resource is occupied by the second information, the first RE subset and the corresponding second RE subset carry the outputs of two times of independent channel coding of the second information respectively. The number of REs included in the first RE subset is different from the number of REs included in the corresponding second RE subset.

  • Patent number: 10608841
    Abstract: Methods and systems for facilitating communication between two or more autonomous system instances include the instantiation of a bridge between the autonomous system (AS) instances. The bridge includes multiple virtual routers each of which is connected using a Layer 2 and a Layer 3 connection to a respective one of the AS instances. For example, each router may be connected to a respective AS instance by each of a virtual local area network (VLAN) connection and a Border Gateway Protocol (BGP) session. To facilitate the BGP session, the bridge may be assigned an AS number (ASN) different than that of each of the AS instances and that is exchanged between the routers and the AS instances. Routing within the bridge may be facilitated by the exchange of interior gateway protocol (IGP) information between the virtual routers.
