Methods, apparatus, and systems for communication over a C-PHY interface are disclosed. A transmitting device has a driver circuit configured to drive a three-wire bus in accordance with a symbol received at an input of the driver circuit, a pattern detector receives a sequence of symbols to be transmitted over the three-wire bus in a plurality of transmission symbol intervals, and a selection circuit responsive to a select signal provided by the pattern detector and configured to select between delayed and undelayed versions of a current symbol to drive the input of the driver circuit during a corresponding transmission symbol interval. The select signal may select the delayed version of the current symbol when a combination of the current symbol with an immediately preceding symbol cause the pattern detector to indicate a pattern match.

The present disclosure discloses a delay jitter compensation method and device, and a computer storage medium. The method includes: determining, by a time stamp compensation component, a current delay jitter of a data link layer according to the latest recorded data cumulant and a fixed value of data cumulant, the fixed value of data cumulant indicating a value of data cumulant without any delay jitter in the data link layer; and acquiring, by the time stamp compensation component, an initial time stamp recorded in a protocol layer, and compensating the initial time stamp according to the current delay jitter of the data link layer to obtain a compensated time stamp, the compensated time stamp being a time stamp obtained by compensating the initial time stamp.

The present invention discloses a method for configuring an operation mode of a remote transceiver unit connected to an access node via a communication line, the remote transceiver unit being operable in at least two operation modes: a Time Division Duplex, TDD, mode and a full duplex, FDX, mode; the method comprising, by the access node: a) obtaining a channel characteristic derived from channel measurements performed over the communication line, b) determining the operation mode of the remote transceiver unit as the FDX mode or the TDD mode based on the channel characteristic; c) transmitting an indication indicating the determined operation mode to the remote transceiver unit.

An electronic device comprises a synchronisation system that receives a signal clocked by a first clock signal having a first frequency and receives a second clock signal having said first frequency, but offset in phase from the first clock signal. The signal is delayed by an adjustable delay period. It is determined whether, following a logic transition in the delayed signal, the next clock edge received is an active edge or is a non-active edge. A calibration controller increases the delay period when the next clock edge is a non-active edge and maintains or decreases the delay period when the next clock edge is an active edge, or decreases the delay period when the next clock edge is an active edge and maintains or increases the delay period when the next clock edge is a non-active edge.

A method for communication in a network that includes multiple nodes having respective network interfaces and interconnects between the network interfaces, which include at least first and second network interfaces connected by a physical interconnect having a given latency. The method includes defining a target latency, greater than the given latency, for communication between the first and second network interfaces. Data are transmitted between the first and second network interfaces over the physical interconnect while applying, by at least one of the first and second network interfaces, a delay in transmission of the data corresponding to a difference between the target latency and the given latency.

A method may include obtaining sensor data from one or more LiDAR units and determining a point-cloud corresponding to the sensor data obtained from each respective LiDAR unit. The method may include aggregating the point-clouds as an aggregated point-cloud. A number of data points included in the aggregated point-cloud may be decreased by filtering out one or more of the data points according to one or more heuristic rules to generate a reduced point-cloud. The method may include determining an operational granularity level for the reduced point-cloud. An array of existence-based objects may be generated based on the reduced point-cloud and the operational granularity level.

A device determines a first latency value of a first data flow from a first physical port of the device to a second physical port of the device and a second latency value of a second data flow from the second physical port to the first physical port, where the first latency value is less than the second latency value. The device determines a first target latency value based on the first latency value and the second latency value. The device adjusts a latency value of the first data flow to the first target latency value.

One exemplary aspect relates to normalizing latency in a networking environment to reduce the chances of creating an unfair advantage. While an exemplary aspect will be discussed in relation to a gaming environment, it is to be appreciated that the techniques disclosed herein can be applied to other environments where latency normalization or the ability to maintain latency between various endpoints is desired. For example, other environments include eSporting, on-line betting, fantasy esports, streaming services, etc. Some more specific examples include World of Warcraft®, Overwatch®, H1Z1®, PUBG®, Fortnite®, Realm Royale®, Planet Side 2®, real-time strategy games, slot machines, electronic poker tournaments, etc.

Systems, apparatuses, and methods for utilizing training sequences on a replica lane are described. A transmitter is coupled to a receiver via a communication channel with a plurality of lanes. One of the lanes is a replica lane used for tracking the drift in the optimal sampling point due to temperature variations, power supply variations, or other factors. While data is sent on the data lanes, test patterns are sent on the replica lane to determine if the optimal sampling point for the replica lane has drifted since a previous test. If the optimal sampling point has drifted for the replica lane, adjustments are made to the sampling point of the replica lane and to the sampling points of the data lanes.

Disclosed embodiments relate, generally, to improved data reception handling at a physical layer. Some embodiments relate to end of line systems that include legacy media access control (MAC) devices and PHY devices that implement improved data reception handling disclosed herein. The improved data reception handling improves the operation of legacy systems, and the MAC more specifically, and in some cases to comply with media access tuning protocols implemented at the physical layer.
