  • Patent number: 10383069
    Abstract: The present relates to a node to be integrated in a network of wirelessly connected nodes, to a network system, to method for operating a node of a network, and to a method for communicating within a network. A method is disclosed for communicating within a network of cooperatively synchronized nodes, configured to broadcast data packets to the network during broadcast phases through a flooding mechanism, each data packet comprising hop data. The method comprises, for each broadcast phase, broadcasting a data packet from a source node during a predetermined time slot; and receiving the data packet at one or more destination node during said predetermined time slot. The broadcasting and receiving are repeated according to the hop data, at respective predetermined time slots, wherein each destination node corresponds to a source node in a next execution of broadcasting and the data packet received corresponds substantially to the data packet to be broadcasted in the next repetition.

  • Patent number: 10368365
    Abstract: Methods, systems, and devices for wireless communication are described that support time mask techniques for shortened transmission time intervals (sTTIs) that may enhance low latency communications. Time masks may be identified and applied for transmissions that use sTTIs, in a manner that provides increased portions of sTTI durations having higher transmission power, and thus increase the likelihood of successful reception of such transmissions at a receiver. In some cases, a transmitter, such as a user equipment (UE), may identify one or more sTTIs for transmissions of a first wireless service (e.g., an ultra-reliable low-latency communication (URLLC) service). An sTTI may be identified based on a duration of a TTI associated with the first wireless service being below a threshold duration (e.g., a TTI duration of less than 1 ms may be identified as an sTTI).

  • Patent number: 10355876
    Abstract: In a communication device, when an enabling signal is at a high level and a transmit data is at a high level, that is, in a recessive period, both transistors turn off. Thus, potentials of signal lines are determined by power supply from a second transmitting part to a communications network. When an error frame arises in this state, that is, transistors in the other ECU turn on, excessive currents flow the signal lines. When current monitoring circuits detect error currents, an error signal is changed to a high level.

  • Patent number: 10356776
    Abstract: Interference caused between neighboring access nodes deploying wireless air-interface resources in different frame configurations while using the same frequency sub-band is mitigated by modifying the subframes deployed by a first access node by muting the subframes in the first frame configuration. Wireless resources from a different frequency sub-band can be aggregated towards the interfering subframes. A third access node adjacent to the first access node may deploy wireless resources in the first frame configuration and using the second frequency sub-band. A determination of how to reconfigure the interfering subframes is based on numbers of wireless devices in potential interference zones between each access node.

  • Patent number: 10348429
    Abstract: A method of facilitating clock synchronization over redundant networks may include, when a SYNC message and a DELAY_REQ message of a PTP clock synchronization cycle are carried by different redundant networks, adjusting a timestamp associated with one of the messages to emulate carriage of the SYNC message and the DELAY_REQ message by the same redundant network. In a method of facilitating PTP clock synchronization, an indicator of an operational status of each of a pair of redundant networks for carrying messages from a slave clock to a master clock may be embedded in a PTP message destined for the slave clock. An indicator of which one of the pair of redundant networks is valid for PTP clock synchronization may be obtained from a PTP message destined for the master clock. PTP messages to the master clock may be selectively relayed based on whether the PTP messages have been received from the valid one of the redundant networks.
