  • Patent number: 10715569
    Abstract: A delivery control device, which is installed in repeater equipment interposed between a content delivery server device and a client device so as to repeat delivered contents, controls delivery speed for contents by adopting pacing delivery depending on delayed conditions of networks and the operating condition of the client device according to the ABR (Adaptive Bit Rate) delivery method. The delivery control device includes a delivery speed calculation part configured to calculate real delivery speed for sequentially delivering the divided files, which are produced by dividing file data representing contents to be delivered to a client device, in an order of reproducing contents, and a delivery speed determination part configured to determine delivery speed for the divided files based on the real delivery speed calculated by the delivery speed calculation part, the presumed delivery speed determined in advance, and predetermined thresholds relating to intervals of receiving the divided files.

  • Patent number: 10708909
    Abstract: Parallel demodulators are provided in field units. Forward and reverse channel allocation information may be broadcast to the field units in the same epoch as traffic data but on first and second channels, such as paging and traffic channels. This assures that all field units are able to receive forward and reverse channel allocation information every epoch. By having parallel demodulators in the field unit, switching between the first and second channels is avoided and channel allocation information is not lost.

    Abstract: Systems and methods for setting a carrier-sensing mechanism in a PLC node are disclosed. In a PLC standard, coexistence is achieved by having the nodes detect a common preamble and backing off by a Coexistence InterFrame Space (cEIFS) time period to help the node to avoid interfering with the other technologies. In one embodiment, a PHY primitive is sent from the PHY to the MAC know that there has been a preamble detection. A two-level indication may be used—one indication after receiving the preamble and other indication after decoding the entire frame.

  • Patent number: 10587373
    Abstract: A method and system to help minimize communication latency. When data is to be transmitted from a transmitting entity to a receiving entity, the transmission will be scheduled to occur in a time interval that selected based on a consideration of the delay-sensitivity of the data and based on a HARQ delay associated with the selected time interval. For instance, if the data is particularly delay-sensitive, then the transmission could be scheduled to occur in a time interval that is selected based on the time interval having a relatively low associated HARQ delay, so as to help reduce the overall delay of the communication. Whereas, if the data is not particularly delay-sensitive, then the transmission could be scheduled to occur in a time interval that has a relatively high associated HARQ delay.

  • Patent number: 10548119
    Abstract: In order to reduce the HS-SCCH overhead, a fixed time allocation approach could be used. In that case, the scheduling time of each VoIP user is semi-static and thus there is no need to transmit e.g. HS-SCCH toward the UE for the initial transmissions, if the UE knows when to receive data on the HS-DSCH and what transport format is used. There are at least two ways of implementing this: 1) HS-SCCH/E-DPCCH signalling to indicate parameters of a first transmission, with subsequent transmissions using the same parameters (and HS-SCCH/E-DPCCH always sent when changes needed), or 2) fixed allocation, RRC signalling used to allocate users and tell the default transport parameters.

During a second selected slot-offset in the TSCH hopping pattern, the gateway node communicates with a secondary network node. A communication schedule identifies the source and destination nodes and channel frequency for each slot-offset. The communication schedule is set such that the CSMA wake-up period for the secondary network is synchronized with the second slot-offset in the TSCH hopping pattern.

  • Patent number: 10396913
    Abstract: An adaptive file delivery system and method transmits a data file, such as an audio-video file, over a network or collection of networks in segments, each segment transmitted during a different time period. Each time period has a transmission portion to transmit its associated file segment and a wait portion in which no further interaction with the network occurs regarding the transmitted segment. In some implementations, the duration of the transmission portion of each time period is sufficient to reach a steady-state throughput condition, which allows the traffic load status of the network or networks to be determined from rate measurements of file segment transmissions. A peak flow determination is made to assure that the delivery of file segments does not cause network congestion. The system has spurious peak rejection to avoid the false detection of network congestion.

  • Patent number: 10270850
    Abstract: A method to reduce group reformation time and maintain seamless connectivity in a peer-to-peer network at the time of disappearance of the Group Owner (GO). Each of the nodes is provided with an emergency leader list which prioritizes a predetermined number of emergency leader nodes each of which is a client node having intent of acting as an emergency leader, wherein the emergency leader list is prepared right at the time of group formation. The emergency leader nodes broadcast beacons when a leader node disappears from the group without notice. Each of the client nodes barring a first-priority emergency leader node of the emergency leader list connects to a highest priority one of emergency leader nodes detected by the client node.

  • Patent number: 10206190
    Abstract: A system, apparatus and method for selecting one or more synchronization stations, or masters, in a peer-to-peer communication environment. Synchronization (or sync) stations broadcast periodic synchronization frames to advertise future availability windows, during which devices rendezvous for discovery and communication. Devices that can act as sync stations advertise preference values, which indicate their preference or suitability for the role. All devices execute the same algorithm to sort the preference values and identify a root sync station and any number of branch sync stations; leaf devices synchronize with the root or a branch sync station. This passive synchronization scheme allows individual devices to conserve power, because they need not actively discover other devices and services, and can power off their radios for periods of time without sacrificing discoverability.

  • Patent number: 10164840
    Abstract: An approach is provided for configuring multiple interferers. An interference effect minimum protective distance is calculated in response to detection of an input of an interferer parameter. Physical (PHY) layer modeling is performed to individually apply a pathloss caused by a separation distance between an interferer node and a victim and apply a pathloss of each node to an attenuator and a transmitter amplifier in an HW manner. MAC layer modeling is performed to determine a transmission node and a transmission time using Markov chain or determine a transmission node and a transmission time using a result log file of an external MAC simulator and a transmission/reception time is reflected in an HW manner by turning ON/OFF a switch. Multiple correlated interferer signals are generated for analyzing an effect of frequency interference in view of both of PHY and MAC layers.

  • Patent number: 10153864
    Abstract: A relay for a telecommunications system comprises a decoder which responds to received blocks corresponding to successive code words xS,t transmitted simultaneously by sources during T time slots. At each slot t, t=1, . . . , T, a code word xS,t comprises B blocks xS,t(1), xS,t(2), . . . , xS,t(B). The first can be decoded independently of the other blocks, to estimate for each source code words xS,t. It also comprises a detector which detects messages that have been decoded without error and takes a decision and an encoder and transmitter which encodes a signal and transmits it to the destination, which signal is representative only of messages that have been decoded without error. When estimating, the decoder takes account of a signal transmitted by another relay representative of messages from the sources that were decoded without error by that relay. The encoder and transmitter is under the control of the detector in accordance with a selection scheme, after each received block.
