  • Patent number: 10149118
    Abstract: Provided are a method and an apparatus for transmitting a multimedia broadcast/multicast service (MBMS) interest indication message in a wireless communication system. A user equipment (UE) receives from a first base station system information for an MBMS which is broadcasted, and transmits the MBMS interest indication message to the first base station when the user equipment performs a handover from a second base station, which does not broadcast the system information for the MBMS, to the first base station.

The plurality of carriers are to be transmitted within a downlink beam via a transponder, each of the carriers is associated with a region of the beam, and the total power allocated to the carriers does not exceed a desired aggregate power level for the transponder. The signal power allocated to each carrier is determined relative to a gain realizable by satellite terminals within the respective beam region and assigned to receive the respective carrier, and the realizable gain of the terminals is based on locations within the beam. The signal power level allocated to each carrier is different from the power allocated to the other carriers.

  • Patent number: 10091114
    Abstract: Methods and systems of asynchronous access and synchronous transmission include transmitting an initial reservation packet using a first protocol to prevent other devices that use the first protocol from transmitting during a reserved duration. A carrier using a second protocol is activated. Information is transmitted using a second protocol during the reserved duration. During a last subframe of the reserved duration, an additional reservation packet is transmitted using the first protocol to extend the reserved duration. The transmission of the additional reservation packet takes place while the carrier using the second protocol is still active.

  • Patent number: 10050680
    Abstract: A method of signal processing, or corresponding apparatus, includes providing digital input signals representing beamforming data to be transmitted on respective antennas. One of the digital input signals is selected at a time among a plurality of times, to cycle through the digital input signals repeatedly and provide a multiplexed digital signal, which is converted to a multiplexed analog signal. The multiplexed analog signal is filtered to pass a predetermined frequency band and demultiplexed to provide analog output signals. One of the analog output signals is selected and provided to a corresponding antenna for transmission. Sharing a transmitter and DAC among multiple antennas results in reduced cost and power. Such cost and power reductions in turn enable larger antenna arrays than are available with prior art techniques, thereby promoting increased throughput and coverage.

  • Patent number: 10020984
    Abstract: In one example, a merge point network device (MP) receives a plurality of resource reservation request messages for establishing a plurality of label switched paths (LSPs), wherein each of the plurality of LSPs has a common point of local repair network device (PLR) and has the MP as a common MP, wherein each of the resource reservation request messages identifies a common bypass tunnel that extends between the PLR and the MP and avoids a protected resource. The MP stores an association between the bypass tunnel and each of the plurality of LSPs. The MP receives a single message to trigger creation at the merge point network device of backup LSP state information for all of the plurality of LSPs. In response to receiving the single message, the MP installs state information for all of the LSPs that correspond to the bypass tunnel according to the stored association.

  • Patent number: 10009266
    Abstract: One embodiment provides a system for facilitating efficient communication of a collection of interests. During operation, the system receives, by an intermediate node, a first packet which has a name and a first nonce, wherein the first packet indicates a set of member interests, wherein a member interest has a name. In response to not obtaining a matching entry in a pending interest table based on the name for the first packet, the system creates a new entry in the pending interest table, wherein an entry includes a second nonce, a reference count, and a set of arrival nonces and corresponding arrival interfaces. The system sets the new entry's second nonce to a new nonce, and sets the new entry's reference count to a number of member interests indicated in the first packet. The system forwards the first packet, wherein the first nonce is replaced with the new nonce.

  • Patent number: 10003452
    Abstract: According to the network-side teachings herein, transmission adaptations taken with respect to a secondary serving cell provide improved operation in the context of serving a half-duplex wireless device having a carrier aggregation configuration involving primary and secondary cells with different Time Division Duplex (TDD) uplink/downlink configurations. Transmission adaptations are taken with respect to a normal downlink subframe in a secondary cell that is time-wise overlapped by a special subframe in the primary cell. Similarly, improved operations are obtained on the device-side according to reception adaptations taken with respect to normal downlink subframes in a secondary cell that are overlapped by special subframes in the primary cell. Non-limiting improvements include better channel estimation and link adaptation, improved scheduling, and revised timings for the transmission and reception of user or control data targeting the device.

  • Patent number: 9967191
    Abstract: In one embodiment, a receiver device determines that it accepts flow entropy, and accordingly determines a set of entropy labels the receiver device is accepting. After transmitting the set of entropy labels from the receiver device to one or more sender devices, the receiver device may then receive packets from the one or more sender devices with selected particular entropy labels from the set of entropy labels. In another embodiment, a sender device receives from a receiver device a set of entropy labels the receiver device is accepting. As such, when determining a packet to forward to the receiver device with flow entropy, the sender device may select a particular entropy label from the set of entropy labels for that receiver device, and transmits the packet device to the receiver device with the selected particular entropy label.
