  • Patent number: 11115869
    Abstract: A bandwidth sharing method and device based on SDN control of terminal cell are disclosed. The bandwidth sharing method includes: determining, by a SDN controller, whether a trigger request for bandwidth sharing is received; upon receipt of the trigger request, selecting at least one second terminal cell for providing bandwidth sharing to the first terminal cell; controlling the first terminal cell and the at least one second terminal cell to jointly process the target service. The trigger request indicates a need of bandwidth sharing of a first terminal cell from other terminal cells when processing a target service on a backhaul link, and a bandwidth requirement of the target service equals to or exceeds a first predetermined threshold. The SDN controlled bandwidth-sharing scheme may ensure the application of a wireless backhaul sharing mechanism between T-SCs, thereby achieving flexible configuration of bandwidth resources on the backhaul link.

  • Patent number: 11089527
    Abstract: An access network can allocate a bearer for a network service associated with a quality-of-service (QoS) value (QV) and a retention-priority value (RPV), and determine a bearer ID for the service based on the QV, the RPV, and a supplemental priority value (SPV) different from the QV and from the RPV. Upon handover of a terminal, session(s) carried by a bearer allocated by the terminal can be terminated. That bearer can be selected using IDs of the bearers and a comparison function that, given two bearer IDs, determines which respective bearer should be terminated before the other. Upon handover of a terminal to an access network supporting fewer bearers per terminal than the terminal has allocated, a network node can select a bearer based on respective QVs and RPVs of a set of allocated bearers. The network node can deallocate the selected bearer.

  • Patent number: 10972391
    Abstract: In one embodiment, a device in a network identifies a packet to be sent to a destination in the network via a path using segment routing. The device determines a list of one or more unique identifiers for one or more of the nodes along the path. The device includes a segment routing header with the packet, the segment routing header comprising a set of segment identifiers and the list of one or more unique identifiers. The device sends the packet with the segment routing header towards the destination in the network.

    Abstract: Embodiments herein describe a SoC that includes a mapper that identifies a destination ID for routing a transaction through a NoC. In one embodiment, the NoC includes ingress and egress logic blocks which permit hardware elements in the SoC to transmit and receive data using the NoC. In one embodiment, the ingress logic blocks can include the mapper that identifies a destination ID for each transaction. In one embodiment, the mapper can receive a destination ID from the hardware element that submitted the transaction to the ingress logic block. In this case, the mapper can bypass the address map by using the provided destination ID. If a destination ID is not provided, however, the mapper can use an address provided in the transaction to identify the destination ID.

  • Patent number: 10959223
    Abstract: Methods, systems, and devices are described for vehicle-to-everything (V2X) communication over one or more determined transmission time intervals (TTIs) in an unlicensed (shared) radio frequency spectrum band. A user equipment (UE) such as a vehicle may perform one or more listen-before-talk (LBT) mechanisms on the shared radio frequency spectrum and contend for access to available system resources. Upon gaining access, the UE may determine a data payload for transmission. The data type or payload may exceed a threshold and as a result, the UE may bundle a multiple TTIs for continuous data transmission. The UE may send control information, indicating a TTI bundling implementation as well as modification to the control or LBT symbols of subsequent TTIs of the data transmission, and subsequently perform data transmission over a plurality of TTIs.

  • Patent number: 10944518
    Abstract: A wireless communication device (alternatively, device, WDEV, etc.) includes at least one processing circuitry configured to support communications with other WDEV(s) and to generate and process signals for such communications. In some examples, the device includes a communication interface and a processing circuitry, among other possible circuitries, components, elements, etc. to support communications with other WDEV(s) and to generate and process signals for such communications. The WDEV generate a first orthogonal frequency division multiple access (OFDMA) frame that specifies information regarding resource unit (RUs) to be used by other WDEV. The WDEV transmits the first OFDMA frame to other WDEVs and receives a second OFDMA frame from the WDEVs based on some RUs specified within the first OFDMA frame. The WDEV then generates and transmits a third OFDMA frame to the other WDEVs (e.g., based on RU(s) spanning RU(s) within which information is received in the second OFDMA frame).
