  • Patent number: 10735157
    Abstract: A dynamic UE capability message specifying a number of beams to be evaluated within different groups of UE TX beam directions associated with different antenna arrays of a UE may be communicated to a transmit receive point (TRP). Each group of UE TX beam directions may include beam directions that are candidates for uplink data transmission. Based on information in the dynamic UE capability message, the TRP can assign SRS resources (for uplink beam management or uplink channel sounding) and/or schedule a multi-layer MIMO uplink transmission in accordance with a UE capability constraint. This may ensure that the SRS resources assignment and/or scheduled multi-layer MIMO uplink transmission is consistent with the UE's beamforming capabilities.

  • Patent number: 10735138
    Abstract: A method for generating a code, a method for encoding and decoding data, and an encoder and a decoder performing the encoding and decoding are disclosed. In an embodiment, a method for lifting a child code from a base code for encoding and decoding data includes determining a single combination of a circulant size, a lifting function, and a labelled base matrix PCM according to an information length and a code rate using data stored in a lifting table. The lifting table was defined at a code generation stage. The method also includes calculating a plurality of shifts for the child code. Each shift is calculated by applying the lifting function to the labelled base matrix PCM with a defined index using the circulant size and using the derived child PCM to encode or decode data.

  • Patent number: 10728098
    Abstract: Disclosed herein are various embodiments for constructing an abstract domain topology. In one embodiment, a Path Computation Element (PCE) is configured as a parent PCE to at least one child PCE. Each of the child PCEs is responsible for providing path computational services for a domain. Communication is established between the parent PCE and the at least one child PCE. The parent PCE receives from each of its child PCEs domain connection information corresponding to the domain of each child PCE. The parent PCE builds and maintains an abstract domain topology based on the domain connection information that it receives from its child PCEs. In one embodiment, the domain connection information is communicated from the child PCE to the parent PCE by adding a new notification-type (NT) and notification-value (NV) to a notification object in a Path Computation Element Communication Protocol (PCEP) notification message.

  • Publication number: 20200236035
    Abstract: Metadata may be embedded in a service chain header (SCH) appended to a packet that is forwarded over a service chain path. The metadata may include information that is used to process the packet at a downstream service function chain (SFC) entity on the service chain path. The metadata TLV field may identify a service action to be performed by a downstream SFC entity. For example, the metadata TLV field may instruct the downstream SFC entity to drop the packet, to redirect the packet (or a traffic flow associated with the packet), to mirror a traffic flow, to terminate a communication connection, to start or stop a packet accounting, and/or to apply a higher grade of service. Alternatively, the metadata TLV field specifies an OAM service action list that identifies service actions that have been performed on the packet.

  • Patent number: 10715447
    Abstract: A T-SDN controller including a T-LSP manager, a temporal path element, a T-TED, a T-LDB, a T-LSPDB, and a network interface. The T-LSP receives a path request including time intervals and a set of constraints. The temporal path element obtains traffic engineering information and computes a path satisfying time intervals and a set of constraints. The T-TED reserves bandwidth corresponding to the path during the time intervals upon request by the T-LSP manager. The T-LDB reserves labels for the links during the time intervals upon request by the T-LSP manager. The T-LSPDB stores the time intervals, the set of constraints, the labels, and the bandwidth. The network interface permits the T-LSP manager to communicate with the nodes in the network to establish a temporal LSP along the path as computed.

  • Patent number: 10707562
    Abstract: An antenna's resonance frequency is detuned when a part of a human body approaches or contacts the antenna and consequently results in efficiency loss. The antenna may be tuned by changing its total load capacitance such that the antenna's total load capacitance falls within a reference capacitance range of a reference capacitance, where the antenna can operate at or near its pre-determined operating resonance frequency. A tunable capacitor may be coupled to the antenna for tuning the total load capacitance of the antenna.
