  • Patent number: 10462797
    Abstract: Methods and apparatus for using communications channels corresponding to frequency bands subject to cellular network, e.g., LTE, interference and/or other interference are described. The methods are well suited for use of cable networks where communications over a coax cable or via cable device may be subject to LTE interference. In various embodiments data traffic is classified based on whether the traffic corresponds to a protocol that supports a retry communications mechanism in the event of a communication error, the type of traffic data and/or the priority of the traffic data. In some embodiments data being communicated using a protocol which supports a retry mechanism are routed over channels subject to interference even if, in some cases, the packets correspond to data which has a higher priority or QoS requirements than packets, e.g., best effort packets, which are transmitted using a protocol that does not support a packet retry mechanism.

  • Patent number: 10432516
    Abstract: Servicing a pseudowire communication across multiple Administrative Systems (AS) by components of packet data networks. A first Provider Edge (PE) router of a first AS receives a first Interior Gateway Protocol (IGP) message from a source PE router of the first AS that includes pseudowire data. The first PE router creates a first Border Gateway Protocol Link State (BGP-LS) message that includes the pseudowire data and transmits the first BGP-LS message to a second PE router of a second AS and intended for a destination PE router of the second AS. The first PE router then receives a second BGP-LS message from the second PE router that includes modified pseudowire data. The first PE router creates a second IGP message that includes the modified pseudowire data and transmits the second IGP message to the source PE router.

  • Patent number: 10425788
    Abstract: The present disclosure relates to a clustering approach for sensor nodes of a wireless sensor network. This clustering approach, equal distance different members, balances the power burden amongst sensor nodes by deriving an optimal number of sensor nodes at each segment of a length. To this end, the present disclosure describes a linear wireless sensor network wherein the distance between adjacent cluster heads is equal while the number of and distance between sensor nodes in each cluster is different. A power consumption model is derived to aid in the determination of the optimal number of sensor nodes within each cluster. Following evaluation of the cluster approach in comparison with previously described approaches, the present disclosure is observed to improve network longevity and reduce power consumption by deliberately increasing the density of sensor nodes nearest a base station.

  • Patent number: 10419166
    Abstract: The present invention discloses a data retransmission method, a device, and a system, and relates to the communications field, so as to resolve a prior-art problem that when a device transmits data by using an unlicensed carrier, the data cannot be retransmitted because a channel needs to be preempted again. A specific solution is as follows: A first device transmits data to a second device by using a first carrier, where the first carrier is an unlicensed carrier. The first device obtains status information of the first carrier, where the status information is used to determine whether the first carrier is available. When the first carrier is unavailable, the first device retransmits the data to the second device by using a second carrier, where the first carrier and the second carrier are different carriers. The present invention is used for data retransmission.

  • Patent number: 10405264
    Abstract: A pairing scheme may add devices to a mesh network automatically. Assuming that at least one device is already part of the mesh network, this scheme may allow devices that have not been paired yet to be automatically added to the mesh, eliminating manual pairing processes. When a new device is powered on, it may broadcast a connectable advertisement packet. The payload of this packet may be secure and not understood by the recipient device. Rather, only a server may have a copy of the device key, and can thus decrypt the advertising packet. The server sends a packet back with a network key and information, and the device then becomes part of the network.

  • Patent number: 10367672
    Abstract: Methods, systems, and devices for wireless communication are described. In one example, phase-noise compensation tracking signals (PTRS) may be transmitted using sets of resource blocks (RBs), where a frequency for each PTRS within the sets RBs is different from a frequency corresponding to a direct current (DC) tone. In another example, a time-domain-based PTRS may be used, where a discrete Fourier transform (DFT)-spread-orthogonal frequency division multiplexing (DFT-s-OFDM) symbol may include a cyclic prefix and a PTRS inserted in the DFT-s-OFDM symbol. Additionally or alternatively, a guard-interval-based DFT-s-OFDM symbol may include a PTRS that replaces part or all of a guard interval. In some examples, subsets of tones used for PTRS across a system bandwidth may be transmitted using a scrambled modulation symbol, where at least one antenna port may be used for the transmission of PTRS.
