  • Patent number: 11115845
    Abstract: Methods and systems for citizens broadband radio service (CBRS) interference management using dual subscriber identification module (SIM) devices are described. The method includes assigning a physical cell identity (PCI) to each CBRS device (CBSD) granted unlicensed spectrum by a spectrum access system (SAS). Each spectrum granted CBSD may exchange PCIs with neighbor spectrum granted CBSDs to resolve PCIs and maintains a PCI table. A dual SIM device may be connected to a CBSD via a first SIM. Each spectrum granted CBSD having a connected dual SIM device reports a number of PCIs detected by the dual SIM device(s). A SAS designated dual SIM device may use a second SIM to measure power values of PCIs detected by the designated dual SIM device which are absent from a provided PCI table. The measured power values may be used by the SAS to make cluster interference decisions.

  • Patent number: 11088757
    Abstract: Embodiments provide high-throughput, hub-and-spoke satellite communications with geographically non-overlapping user beams and full frequency reuse. For example, a coverage area of a satellite is segmented into multiple candidate coverage zones, and an associated consumption demand is determined for each candidate coverage zone. Fixed spot beams are assigned to a subset of the candidate coverage zones according to highest associated consumption demands, such that each fixed spot beam corresponds to at least one candidate coverage zone to service an associated beam coverage area that is geographically non-overlapping with beam coverage areas of all other fixed spot beams, and each fixed spot beam is allocated full use of a same spectrum. One or more steerable beams selectively cover lower consumption demand zones.

  • Patent number: 11089558
    Abstract: A resynchronization signal (RSS) may extend across multiple physical resource blocks (PRBs) or subframes, which may cause the RRS to be scheduled to overlap with other downlink transmissions. Methods, systems, and devices for wireless communications are described for management of RSS and one or more other transmission types that may have overlapping wireless resources with the RSS. If one or more other downlink transmissions are scheduled for resources that overlap with resources scheduled for an RSS transmission, the UE may receive the RSS transmission or the one or more other downlink transmissions, or a combination thereof, based on a prioritization of the transmission types of the one or more other downlink transmissions relative to RSS. The RSS transmission or the one or more other transmissions may be delayed, dropped, punctured, or rate-matched when the RSS transmission and the one or more other downlink transmissions conflict.

  • Patent number: 10924391
    Abstract: Presented herein are systems and methods that provide traffic recover when virtual router redundancy protocol (VRRP) virtual media access control (VMAC) failures occur in a link aggregation group fabric environment. In one or more embodiments, automatic traffic recovery may be accomplished using internode link control messages to synchronize a VRRP VMAC failure that has been encountered by one LAG node with a LAG peer node. If a database associated with the failed LAG node comprises no entry that indicates that the failure scenario has previously occurred in the LAG peer node, a forwarding path entry rule may be generated to route traffic via the internode link, thereby, reducing data loss through routing failures and the like.

  • Patent number: 10855520
    Abstract: A network device selects a primary source for multicast traffic and a secondary source for the multicast traffic, where the multicast traffic is provided to endpoint devices communicating with a network, and where the primary source and the secondary source are redundant sources. The network device provides a first join request that includes information that causes a primary path to be provided from the primary source through the network. The network device provides a second join request that includes information that causes a secondary path to be provided from the secondary source through the network. The network device receives the multicast traffic from the primary source via the primary path and the secondary source via the secondary path, and provides the multicast traffic received from the primary source to the endpoint devices. The network device prevents the multicast traffic received from the secondary source from reaching the endpoint devices.

  • Patent number: 10846020
    Abstract: A drive assisted storage controller system includes a first storage device that is coupled to a bus that includes a data path and a control path. The first storage device receives via the control path from a storage controller, a first peer-to-peer write command that identifies a host memory address included in a memory system, a first storage location provided in the first storage device, and a second storage location provided in a second storage device coupled to the bus. The first storage device retrieves, via the data path from the host memory address, first write data such that the first write data is not provided through the storage controller. The first storage device provides, via the control path to the second storage device, a second peer-to-peer write command that includes the second storage location. The second peer-to-peer write command causes the second storage device to retrieve the first write data from the first storage device via the data path.
