  • Patent number: 11146452
    Abstract: A system for negotiating Ethernet link settings between interconnected nodes in a network having an Ethernet protocol stack that includes a PCS sub-layer with an auto-negotiation function. The system comprises connecting an intermediate device coupled between two network nodes via optical or copper interfaces, with the link settings between each node and the connected intermediate device being the same, thereby bypassing the auto-negotiation of the PCS sub-layer in the intermediate device. The intermediate device may transparently send negotiation messages from each node to the other during the link negotiation phase without interacting with those messages. Instead of the intermediate device, a single form pluggable (SFP) device may be connected between the two network nodes via optical or copper interfaces on the network side and via an SFP slot on the device side.

  • Patent number: 11146420
    Abstract: An extension of the existing CAN FD data transmission protocol. The extension enables the use of the IPv6 protocol for the CAN bus. The CAN FD protocol is further developed in an incompatible way. One modification measure relates to the lengthening of the Data Field, which is positioned in the transmission frame after an Arbitration Field. An arbitrary number of bytes can be entered in the extended Data Field within a specified upper limit. Since the Data Field is transmitted at a higher bit rate field than the Arbitration Field, the data throughput is increased dramatically.

  • Patent number: 11061404
    Abstract: An autonomous vehicle detects a tailgating vehicle and uses various response mechanisms. A vehicle is identified as a tailgater based on whether its characteristics meet a variable threshold. When the autonomous vehicle is traveling at slower speeds, the threshold is defined in distance. When the autonomous vehicle is traveling at faster speeds, the threshold is defined in time. The autonomous vehicle responds to the tailgater by modifying its driving behavior. In one example, the autonomous vehicle adjusts a headway buffer (defined in time) from another vehicle in front of the autonomous vehicle. In this regard, if the tailgater is T seconds too close to the autonomous vehicle, the autonomous vehicle increases the headway buffer to the vehicle in front of it by some amount relative to T.

  • Patent number: 10757694
    Abstract: Data transmission and reception is provided by configuring control channels in a wireless communication system using a plurality of carriers. User equipment (UE) may monitor physical downlink control channel (PDCCH) candidates within common search spaces (CSSs) and User Equipment-specific search spaces (USSs). If the UE is configured with cross-carrier scheduling, when two PDCCH candidates originating from a CSS and a USS, respectively, have cyclic redundancy check (CRC) scrambled by the same Radio Network Temporary Identifier (RNTI) and have a common payload size and the same first control channel element (CCE) index, the UE may interpret that only the PDCCH originating from the CSS is transmitted, thereby solving ambiguity of downlink control information (DCI) detection.

  • Patent number: 10736177
    Abstract: In some configurations, the method of operating a system with dynamic wireless network topology with reduced spectrum flooding involve scanning with a first device in mesh network for beacon packets from other devices in the mesh network during a random back off period. In response to the first device not receiving a beacon packet from the other devices during the random back off period, the first device initiates an election protocol by sending an election protocol packet with its unique election protocol identifier to the other devices. In response to receiving a beacon packet from a second device, the first device stores the unique node identifier, assigns the second device as a leader node device, retransmits the unique node identifier of the second device and leader node information in a protocol packet. A command packet is communicated through the mesh network by way of at least one leader node device.

  • Patent number: 10736141
    Abstract: An electronic device that dynamically adapts RTS-CTS protection is described. During operation, this electronic device may obtain communication parameters associated with communication in a WLAN, which includes the electronic device and a second electronic device. For example, the communication parameters may include a collision probability, a PPDU airtime, an RTS airtime, a SIFS airtime and/or a CTS airtime. Then, the electronic device may determine an RTS-CTS performance metric based at least in part on the communication parameters. For example, the RTS-CTS performance metric may be based at least in part on the collision probability, the RTS airtime, the SIFS airtime, and/or the CTS airtime. Next, the electronic device may compare the RTS-CTS performance metric and the PPDU airtime. Moreover, based at least in part on the comparison, the electronic device may selectively use RTS-CTS protection during communication of a PPDU with the second electronic device.

  • Patent number: 10721790
    Abstract: A method and user node for maintaining a connection with a network node when operating in a multi-carrier mode using a first filter configuration to receive multiple frequency carriers simultaneously for downlink communication. The user node applies a mode switching scheme comprising first intervals for the multi-carrier mode and second intervals for a single carrier mode using a second filter configuration to receive a single carrier for the downlink communication. In this case, the user node switches temporarily from the multi-carrier mode to operate in the single carrier mode during the second intervals according to the mode switching scheme. Thereby the user node is enabled to maintain the connection by receiving messages and/or control signalling from the network node over the single frequency carrier during the second intervals, for example when the multi-carrier mode is highly disturbed by interference.

  • Patent number: 10701616
    Abstract: A data transmission acceleration method and related apparatuses are disclosed. A sanding node transmits a plurality of data packets to a receiving node at an initial transmission rate. Each data packet carries a random sequence number and a rolling sequence number. The random sequence number identifies a data part of the data packet, and the rolling sequence number indicates a transmission sequence of the data packet. The sending node receives a packet loss feedback from the receiving node. The packet loss feedback is generated after the receiving node detects a packet loss event according to a rolling sequence number of a received data packet. The sending node determines a random sequence number of a lost data packet based on the received packet loss feedback. The sending node retransmits a data packet corresponding to the determined random sequence number. The retransmitted data packet carries a new rolling sequence number.
