  • Patent number: 10742740
    Abstract: An in-vehicle network system includes a first control unit, a second control unit, and a network connecting the first control unit to the second control unit. The first control unit performs a process of transmitting data, which is target of high-speed processing, having a first data length obtained by dividing transmission data by the first data length or obtained by adding predetermined data to the transmission data as high-speed processing. The second control unit performs a process of receiving reception data at a first processing speed that is a low speed when the second control unit determines that a data length of the reception data is not the first data length, and performs a process of receiving the reception data at a second processing speed higher than the first processing speed when the second control unit determines that the data length of the reception data is the first data length.

  • Patent number: 10727923
    Abstract: An apparatus has an array of antennae. Each antenna in the array has a tile circuit including a frequency conversion circuit to generate from an incoming reference signal a local oscillator carrier signal operative as an outgoing reference signal for an adjacent tile circuit. A mixer receives the local oscillator carrier signal and combines it with an antenna signal to produce a frequency converted antenna signal. A matrix of phase shifters and variable gain elements produces a set of frequency converted and phase rotated antenna signals. Analog summers combine the frequency converted and phase rotated antenna signals with user input signals from the adjacent tile circuit for distributed analog beam forming of multiple streams. The user input signals correspond to distinct users tracked by the array of antennae.

  • Patent number: 10708194
    Abstract: Dynamic history multistream long range compression (DHC) techniques are described for efficiently compressing multiple, prioritized data streams received over a channel. A history buffer is associated with each received stream and a DHC compressor dynamically allocates fixed sized history sections to and from each history buffer. In implementations, the DHC compressor makes stream history size adjustments prior to compressing a block of data and sends information identifying the change in history size to a DHC decompressor. The DHC decompressor sends signaling information to the DHC compressor that is used to ensure that the DHC decompressor can operate with a fixed amount of total history memory.

  • Patent number: 10693595
    Abstract: In a serial communication interface with transceivers that run on different clocks, an ACK transmit FIFO is used to track packets transmitted, and an ACK receive queue is used to track ACK bits for received packets. The ACK receive queue contains a number of entries, and training for the transceivers begins transmitting ACK bits from the ACK receive queue once the ACK receive queue has multiple valid ACK bits. When the ACK receive queue is less than a lower threshold, an ACK compensation mechanism sends one or more packets that make the ACK receive queue grow. When the ACK receive queue is more than an upper threshold, the ACK compensation mechanism sends one or more packets that make the ACK receive queue shrink. The combination of the ACK receive queue and the ACK compensation mechanism allow dynamically compensating for the different clocks of the two transceivers.

    Abstract: The application layer of a first wireless device may be configured to receive a ranging request indication from a MAC layer of the first wireless device, determine whether the MAC layer should respond to the ranging request, and send a ranging response to the MAC layer with an indication of whether to respond to the ranging request. The MAC layer may be configured to decode a ranging set-up request from a second wireless device, where the ranging set-up request comprises time slots. If an auto-response is set to false, send a ranging request indication to the application layer and receive from the application layer a ranging response, and if the auto-response is set to true or the ranging response indicates the MAC layer should respond to the ranging set-up request, select a time slot, and encode a ranging response with an indication of the selected time slot.

  • Patent number: 10673770
    Abstract: A network device organizes packets into various queues, in which the packets await processing. Queue management logic tracks how long certain packet(s), such as a designated marker packet, remain in a queue. Based thereon, the logic produces a measure of delay for the queue, referred to herein as the “queue delay.” Based on a comparison of the current queue delay to one or more thresholds, various associated delay-based actions may be performed, such as tagging and/or dropping packets departing from the queue, or preventing addition enqueues to the queue. In an embodiment, a queue may be expired based on the queue delay, and all packets dropped. In other embodiments, when a packet is dropped prior to enqueue into an assigned queue, copies of some or all of the packets already within the queue at the time the packet was dropped may be forwarded to a visibility component for analysis.

  • Patent number: 10638361
    Abstract: Methods and apparatus for monitoring and controlling access to coexisting first and second networks within a venue. In one embodiment, the first network is a managed content delivery network that includes one or more wireless access points (APs) in data communication with a backend controller which communicates with a dedicated background scanner. The background scanner scans for coexisting networks within the venue, and reports this to the controller. In one variant, the controller dynamically adjusts transmit characteristics of the AP(s) to manage interference between the coexisting networks. In another variant, the controller causes the energy detect threshold of a client device to be lowered so that the device may detect WLAN signals in a scenario where a coexisting RAT (for example, LTE-U or LTE-LAA) occupies the same channel and/or frequency.

  • Patent number: 10631206
    Abstract: In one implementation, load balancing within a constellation of communications satellites is performed. Anticipated positions of satellites are determined. Each satellite is configured to provide multiple beams that define a coverage footprint for the satellite. Based on the anticipated positions of the satellites, it is determined that a first coverage footprint for a first satellite provides primary coverage of a high traffic region and portions of the first coverage footprint for the first satellite also will be covered by coverage footprints for other satellites, Based on these determinations, a beam assignments are defined in which a first subset of beams of the first satellite configured to provide coverage of a first portion of the first coverage footprint are inactive and a second subset of beams of the second satellite are active. The second subset of beams of the second satellite provide coverage within the first portion of the first coverage footprint.
