  • Patent number: 11115176
    Abstract: Clock-data timing in a multi-lane serial data communication link may be adjusted to compensate for drift. A reference lane may be selected and periodically trained to adjust clock-data timing. In response to initiation of a first lane transitioning from an active state to an inactive state, first information representing the clock-data timing of the reference lane at the time that transition is initiated may be determined. Then, in response to initiation of the first lane transitioning back from the inactive state to the active state, second information representing the clock-data timing of the reference lane at the time that transition is initiated may be determined. The clock-data timing of the first lane may be adjusted based on the first information and the second information.

  • Patent number: 11016920
    Abstract: Aspects of the embodiments are directed to calibrating a cross-talk cancellation module. A data eye response for a first data channel can be acquired, and the left-side and right-side maximum transition edges can be determined while adjacent data channels are silent. The adjacent data channels can be activated, first using an even mode waveform. A strobe can be positioned at the left-side maximum boundary in anticipation of a right-shift due to even mode waveform cross talk. A summer circuit can sum the waveform from the first data channel with cross-talk induced voltage pulse having an opposite polarity from the even mode waveforms on the aggressor channels. A left-side edge can be determined by incrementally adjusting gain and detector parameters. These parameters can be locked once a left-side transition edge is located. The process can be repeated for a right-side transition edge with odd-mode aggressor waveforms.

  • Patent number: 10939421
    Abstract: Various methods of allocating uplink control channels in a communication system are implemented at a resource scheduler or a user equipment (UE). In one method the scheduler reserves resources for a downlink data channel and signals a corresponding downlink data channel grant and also reserves resources for a persistent uplink control channel for a longer duration than the data channel grant. Signaling overhead associated with a grant for this persistent uplink control channel is reduced over a full dynamic grant. A predetermined rule can be used at the scheduler and at the UE to avoid overhead signaling associated with a grant for this persistent control channel. Predetermined rules at the UE and scheduler can also be used to reserve appropriate resources and select appropriate MCS levels for control information and the control information and uplink data can be transported over a common uplink channel when a time overlap occurs between an uplink data channel and the persistent control channel.

  • Patent number: 10931391
    Abstract: Electronic devices coupled to a network may exchange messages containing time-of-day information synchronization of the internal clocks. The information exchanged may include the instant at which a message leaves the electronic device. Discussed herein are methods and systems that allow 1-step timestamping of messages containing time-of-day information. The 1-step timestamping methods and systems may reduce the impact of non-deterministic time delays in the transmit path (e.g., encryption, expansion, inclusion of tags), and may improve the accuracy of the time-of-day information of the packets. For example, systems and methods may allow accurate 1-step timestamping of IEEE 1588 Precision Time Protocol packets with the uncertainty of delays from MACSec encryption or other security mechanisms. Some embodiments employ estimation non-deterministic delay of previously transmitted packets to estimate the state of the transmit path.

  • Patent number: 10901684
    Abstract: An electronic device may exchange packets with a second electronic device. These packets may include transmit times, based on a given clock in a given electronic device when the packets were transmitted. Moreover, when the packets are received by the electronic device, the electronic device may store associated receive times based on a clock in the electronic device. Using minimum time differences between the transmit and receive times, the electronic device may calculate a time offset between the electronic device and the second electronic device, which may then be used to determine future times in a clock domain of the second electronic device. Moreover, the electronic device may provide additional packets to the second electronic device, where a given additional packet includes audio data, and a playback time, corresponding to a given future time, when the audio data is to be played back by the second electronic device.

  • Patent number: 10897762
    Abstract: A wireless communication network that forms an ad-hoc network without the arrangement of a controlling station sets a period that a communication apparatus can utilize with priority and performs isochronous communication in the period as required. When isochronous communication has not been performed or after isochronous communication has finished in the priority utilization period, other communication apparatuses perform arbitrary communication. When another communication is performed in a communication apparatus's own priority utilization period, the start of isochronous communication is temporarily delayed. In an ad-hoc communication environment, data having a real-time characteristic, such as AV content, can be efficiently transmitted through the isochronous communication.

    Abstract: A reception apparatus including a decoding apparatus and a demultiplexing apparatus for identifying a packet with clock information. The decoding apparatus receives a transfer frame, which includes one or more first transfer units obtained by multiplexing contents. A decoder in the decoding apparatus acquires the first transfer units by decoding the transfer frame, and outputs the first transfer units to the demultiplexing apparatus. The demultiplexing apparatus acquires content by demultiplexing the first transfer units. Additionally, a heading first transfer unit, which is positioned at a head within the transfer frame, contains reference clock information. The decoder generates information for identifying the heading first transfer unit and outputs the information to the demultiplexing apparatus.

  • Patent number: 10863469
    Abstract: Systems, devices, and methods synchronize sensor data and timestamps based on a second clock of a second device relative to a first clock of a first device. The data are communicated from the second device to the first device by way of respective wireless circuits in the first and second devices. Timestamps based on the second clock are corrected based on one or more of a time offset value and a clock frequency offset value of the second clock relative to the first clock. The timestamps for the sensor data are scaled to account for clock drift, and shifted to account for clock offset error.
