  • Patent number: 10735150
    Abstract: A multiple-input multiple output (MIMO) wireless receiver is provided to detect data in MIMO streams received via a multi-antenna system. A filter based detector performs a first pass at decoding codewords in a MIMO bitstream, and then a parity check is performed to determine that the codewords were decoded correctly. If one or more codewords are decoded correctly, those codewords can be used as a candidate codeword and used to generate a bit log likelihood ratio as an input for a second MIMO detector pass which uses a list based MIMO detector. The first pass with a high speed, simple detector facilitates decreasing the list size for the second, optimum list based detector which helps improve overall throughput.

  • Patent number: 10728140
    Abstract: Concepts and technologies disclosed herein are directed to deadlock-free traffic rerouting in software-defined networking (“SDN”) networks. According to one aspect of the concepts and technologies disclosed herein, a centralized SDN controller can determine that a packet flow along a path within at least a portion of a network is to be rerouted from the path to a new path. The centralized SDN controller can initiate a reroute of the packet flow to the new path. The centralized SDN controller can request a bandwidth for the new path. The bandwidth can be determined such that bandwidth oversubscription on the new path is avoided. In response to the packet flow settling on the new path, the centralized SDN controller can adjust a requested bandwidth of the packet flow to a desired value to complete the reroute of the packet flow from the path to the new path.

  • Patent number: 10715428
    Abstract: Techniques are described for signaling a resource reservation point-to-multipoint (P2MP) label switched path (LSP) in a ring network. For example, the techniques include sending a single resource reservation request message without the ingress needing to send multiple resource reservation request messages, one for each leaf network device of the P2MP ring LSP. The resource reservation request message includes a leaf identification object from which network devices of a P2MP ring LSP may explicitly or implicitly identify themselves as prospective leaf network devices of the P2MP ring LSP. A network device determined to be a leaf network device may send a resource reservation response message back to the ingress network device of the P2MP ring LSP and send a modified resource reservation request message (if explicit) and/or the same resource reservation request message (if implicit) to a next hop network device along the P2MP ring LSP.

    Abstract: A method and a device in a User Equipment and a base station are provided. The UE receives first information and monitors a first signaling in M Resource Element (RE) sets. The first information determines the M RE sets. The UE assumes that P modulation symbol groups are one-to-one mapped to P RE sets of the M RE sets. One blind detection for the first signaling is performed on the P RE sets. Modulation symbols obtained by modulating the bits in a first bit sequence constitute a first modulation symbol set sequentially. The bits in the first bit sequence are sequentially arranged according to an output of a channel encoder. The first modulation symbol set is successively divided into the P modulation symbol groups, each consisting of X modulation symbols. Relative positions of the P RE sets in frequency domain are related to at least one of {M, X}.

  • Patent number: 10693671
    Abstract: In one embodiment, a cloud-based service instructs one or more networking devices in a local area network (LAN) to form a virtual network overlay in the LAN that redirects traffic associated with a particular node in the LAN to the service. The service receives multicast or broadcast traffic sent by the particular node in the LAN and redirected to the service via the virtual network overlay. The service identifies a group of nodes in the network that are to receive the traffic sent by the particular node, based in part by profiling the traffic associated with the particular node. The service sends the traffic sent by the particular node to at least one networking device in the LAN with an indication of the identified group of nodes in the network that are to receive the traffic sent by the particular node. The at least one networking device forwards the traffic sent by the particular node to the nodes in the identified group.
