摘要： A networking device can use sync request packets to synchronize connection objects with a peer. Real or virtual flow misses occurring in the data plane while processing a network packet indicate that synchronization is needed. A virtual flow miss occurs when a data plane connection object is obsolete. A sync request packet containing connection metadata and the network packets is sent to the peer. The peer uses the connection metadata to create or update its version of the connection object then returns a sync ack packet that contains the network packet. Receiving a sync ack packet can indicate that the locally stored version of the connection object and the peer's version of the connection object are consistent. The network packet may be processed normally when the locally stored version of the connection object and the peer's version of the connection object are consistent.

摘要： Various aspects described herein relate to techniques for synchronization channel design and signaling in wireless communications systems (e.g., a 5th Generation (5G) New Radio (NR) system). In an aspect, a method includes identifying a frequency band supported by a user equipment (UE), identifying one or more frequency locations based on the identified frequency band, and the one or more frequency locations are a subset of synchronization raster points used for synchronization signal transmission. The method further includes searching for at least one synchronization signal based on the one or more identified frequency locations.

摘要： A system and method configured to provide limited-time events to users in an online game. The system and method may include executing an instance of an online game and effectuating presentation of offers to users to activate a limited-time event within the online game. Activation of the limited-time event may enable users to perform event runs through the limited-time event for a duration. The execution of event runs through the limited-time event in response to user commands received from a client computing platform associated with the user may deplete the virtual resource in an inventory of the user. The system and method may maintain inventories of the users and recharge the virtual resource as a function of time. The performance of users may be assessed and awards may be distributed to the users based on the assessment of their performance during the event runs. The system and method may include effectuating exchanges by the users of virtual items for the first virtual resource.

摘要： The present invention allows a gain control to be appropriately effected even when a frame including no preamble signal block is used for wireless communications. The following processes are effected in a transmission power control unit 106 of a transmission unit. Specifically, an automatic transmission gain control unit 201 multiplies a transmission signal by a gain value that is the difference between the power of a signal loop-backed from a power amplifier 109 and the power of the transmission signal. A fixed transmission gain multiplying unit 202 multiplies the transmission signal by a predetermined gain value or by the gain value used in the automatic transmission gain control unit 201 during the preceding frame. A selection unit 203 selects the transmission signal as gain-controlled by the automatic transmission gain control unit 201 in a case of a preamble signal block being included in the frame of the transmission signal and selects the transmission signal as gain-controlled by the fixed transmission gain multiplying unit 202 in a case of no preamble signal block being included in the frame of the transmission signal.

摘要： A clock and data recovery circuit is disclosed herein. The clock and data recovery circuit includes a phase detection unit, a charge pump, a loop filter, a voltage control oscillator, and a frequency detection unit. The voltage control oscillator has oscillation frequency that is variable in response to a frequency adjustment signal, and outputs an oscillation signal. The frequency detection unit includes a reference clock divider, a counter, and an oscillation frequency control unit. The reference clock divider generates a count-enable signal based on a reference clock signal. The counter generates an oscillation count signal by counting the pulses of the oscillation signal of the voltage control oscillator or the pulses of divided signals resulting from dividing the oscillation signal while the count-enable signal is being enabled. The oscillation frequency control unit compares a target count value with the value of the oscillation count signal, and outputs the frequency adjustment signal.

摘要： A method includes receiving an optical signal through an optical link and determining a receiving power for the optical link. The method further includes comparing the receiving power for the optical link to a first receiving power threshold and transitioning a clock and data recovery circuit form a normal mode to a holdover mode when the receiving power is less than the first receiving power threshold. The clock and data recovery circuit, when operating in the holdover mode, configured to hold a recovered clock to a known-good clock frequency. When the receiving power for the optical link is greater than a second receiving power threshold, the method initiates a transition of the clock and data recovery circuit from the holdover mode to the normal mode and reacquires synchronization between the recovered clock and a current rate of the incoming data stream using the known-good clock frequency.

摘要： The present embodiment relates to, for example, a transceiver system capable of notifying a transmission device of an asynchronous state of a reception device with a simple configuration. The reception device includes an input unit, a synchronous-state detector, a resistance-value controller, and a terminal resistor. When the synchronous-state detector detects the asynchronous state, the resistance-value controller sets a resistance value of the terminal resistor to a resistance value indicating the asynchronous state. The transmission device includes an output unit, an amplitude detector, an output controller, and a transmission resistor. The output controller causes the output unit to output a signal constituting normal data including clock information when the synchronous state of the reception device is detected, and causes the output unit to output a signal constituting training data including the clock information when the asynchronous state of the reception device is detected.
