摘要： A multi-level signal receiver includes a data sampler having (M−1) sense amplifiers therein, which are configured to compare a multi-level signal having one of M voltage levels with (M−1) reference voltages, to thereby generate (M−1) comparison signals. The data sampler is further configured to generate a target data signal including N bits, where M is an integer greater than two and N is an integer greater than one. An equalization controller is provided, which is configured to train the (M−1) sense amplifiers by: (i) adjusting at least one of (M−1) voltage intervals during a first training mode, and (ii) adjusting levels of the (M−1) reference voltages during a second training mode, based on equalized values of the (M−1) comparison signals, where each of the (M−1) voltage intervals represents a difference between two adjacent voltage levels from among the M voltage levels.

摘要： The present invention discloses a signal relay apparatus having frequency calibration mechanism that includes a clock generation circuit, a frequency generation circuit, a clock measuring circuit, a frequency adjusting circuit and a transmission circuit. The clock generation circuit generates a source clock signal. The frequency generation circuit receives the source clock signal and generates a target frequency signal according to a conversion parameter. The clock measuring circuit measures a first frequency offset of a source frequency relative to a first predetermined frequency according to an external reference clock signal. The frequency adjusting circuit adjusts the conversion parameter according to the first frequency offset when the first frequency offset is not within a first predetermined range such that a second frequency offset of a target frequency relative to a second predetermined frequency is within a second predetermined range. The transmission circuit performs signal transmission according to the target frequency signal.

摘要： A base station (UE) is configured to perform a computer-implemented method for antenna fault detection and correction. The computer-implemented method includes acquiring one or more sounding reference signals (SRSs) received from at least one gNB antenna; detecting an antenna failure based on the one or more SRSs; estimating a noise power based on the antenna failure and a history of received SRSs; detecting a missing SRS based on the noise power and the history of received SRSs; and handling the missing SRS. Handling the missing SRS is based on performing at least one of: replacing an SRS measurement with a predicted SRS value for the missing SRS when the predicted SRS is available; or avoiding use of the missing SRS in a sequential SRS prediction when the predicted SRS is unavailable.

摘要： A low voltage drive circuit includes a transmit digital to analog circuit that converts transmit digital data into analog outbound data by: generating a DC component; generating a first oscillation at a first frequency; generating a second oscillation at the first frequency; and outputting the first oscillation or the second oscillation on a bit-by-bit basis in accordance with the transmit digital data to produce an oscillating component, wherein the DC component is combined with the oscillating component to produce the analog outbound data, and wherein the oscillating component and the DC component are combined to produce the analog outbound data. A drive sense circuit drives an analog transmit signal onto a bus, wherein the analog outbound data is represented within the analog transmit signal as variances in loading of the bus at the first frequency and wherein analog inbound data is represented within an analog receive signal as variances in loading of the bus at a second frequency.

摘要： Methods, systems, and apparatuses related to memory operation with common clock signals are provided. A memory device or system that includes one or more memory devices may be operable with a common clock signal without a delay from switching on-die termination on or off. For example, a memory device may comprise first impedance adjustment circuitry configured to provide a first impedance to a received clock signal having a clock impedance and second impedance adjustment circuitry configured to provide a second impedance to the received clock signal. The first impedance and the second impedance may be configured to provide a combined impedance about equal to the clock impedance when the first impedance adjustment circuitry and the second impedance adjustment circuitry are connected to the received clock signal in parallel.

摘要： To schedule panel specific uplink transmissions, the UE may assist in the scheduling of the panel specific uplink transmission by improving the manner in which the specific panel is indicated for uplink transmission. The apparatus receives, from a base station, an indication of a UE panel for an uplink transmission. The apparatus determines a Tx panel at the UE based on the indication of the UE panel. The apparatus transmits, to the base station, the uplink transmission using the Tx beam associated with the Tx panel.

摘要： A method and devices for configuring a data transmission network are disclosed. The method is for configuring a data transmission network, executed by a configuration device, wherein the data transmission network comprises at least one transmitter, at least one receiver with a communication channel between the transmitter and the receiver, the method comprising: training a machine learning model of the data transmission network, wherein the machine learning model comprises at least a transmitter model including a transmitter neural network, a channel model, and a receiver model including a receiver neural network by providing a message within a sequence of messages; generating a group of transmission symbols for each message in the sequence of messages using the transmitter neural network; concatenating the groups of transmission symbols together as a sequence of transmission symbols; simulating transmission of the sequence of transmission symbols over the communication channel using the channel model to the receiver; analysing a sequence of received symbols using the reception neural network to generate a decoded message; and updating the machine learning model based on an output of said reception neural network. In this way, the machine learning model can be trained using representative sequences of message, which improves performance when deployed in a real network.
