Abstract: An analog-to-digital converter (ADC) has been disclosed. In some implementations, the ADC is configured to generate ADC samples based on input signals and an ADC input clock. The ADC is further configured to generate at a first time point a synchronized start signal indicating a starting point of capturing the ADC samples. The start signal and a system clock can be synchronized at a second time point. At a third time point, a capturing sample clock for capturing the ADC samples is generated. The synchronized start signal and the capturing sample clock can be input to a counter to determine a time difference between the second and third time points. An ADC output timing of the ADC samples can be determined based on the time difference.

Abstract: Aspects of the present disclosure provide signal amplification. An example method generally includes amplifying a version of a first input signal with a power amplifier in a first state where a bias voltage of the power amplifier is set to a first voltage based on a first tracking mode; obtaining a first output signal of the power amplifier in a second state where the bias voltage is set to a second voltage less than the first voltage; determining a predistortion associated with the power amplifier based at least in part on the obtained first output signal; applying the predistortion to the first input signal; and amplifying a version of the predistorted first input signal with the power amplifier in a third state where the bias voltage is set to a third voltage based on a second tracking mode, wherein the third voltage is less than the first voltage.

Abstract: A UE may attempt, based on a first mode, to identify a first opportunity within a preconfigured time period for a measurement associated with at least one SCC when the at least one SCC is deactivated at the UE and the measurement associated with the at least one SCC is due based on a scheduling. Based on the first mode, a radio of the UE may not be tuned to the at least one SCC when the at least one SCC is deactivated at the UE and no measurement associated with the at least one SCC is being performed at the UE. The UE may perform, if the first opportunity is identified within the preconfigured time period, the measurement associated with the at least one SCC at the identified first opportunity.

Abstract: Certain aspects of the present disclosure provide techniques for identifying a minimal, or at least reduced, set of representative calibration paths in radio frequency (RF) circuits and calibrating other calibration paths based on calibration codes used for the representative calibration paths. An example method generally includes receiving a calibration data set including measurements associated with each calibration path of a plurality of calibration paths in an RF circuit. Based on a clustering model and the calibration data set, a plurality of calibration clusters is generated. From each respective calibration cluster of the plurality of calibration clusters, a respective representative calibration path for is selected for the respective calibration cluster. Generally, calibration codes generated for the representative calibration path are applicable to other calibration paths in the calibration cluster. A lookup table is generated associating a respective calibration path with other calibration paths in each respective calibration cluster.

Abstract: According to embodiments, an example UE may include means for obtaining a set of ADC samples generated by an ADC based on analog signals and an ADC input clock and means for generating, at a first time point, a start signal indicating a starting point of capturing the set of ADC samples. The UE may also include means for synchronizing, at a second time point, the start signal and a system clock and means for generating, at a third time point, a capturing sample clock for capturing the set of ADC samples. The means may further include means for inputting the start signal and the capturing sample clock to a counter to determine a time difference between the second time point and the third time point and means for determining the ADC output timing of the set of ADC samples based on the time difference.

Abstract: According to embodiments, an example method for determining an analog-to-digital converter (ADC) output timing in a user equipment may include operating a switch in a first mode to route a system clock from an oscillator to an input of the ADC and determining a first ADC output timing based on a first set of ADC samples generated by the ADC. The method may also include operating the switch in a second mode to route analog signals from a transceiver of the user equipment to the input of the ADC and obtaining a second set of ADC samples generated by the ADC based on the analog signals.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless node may receive a configuration indicating a parameter of a signal to be optimized for a portion of a frequency range. The wireless node may transform a feedback signal and a reference signal into a frequency domain. The wireless node may generate an error signal based at least in part on transforming the feedback signal and the reference signal. The wireless node may assign weights to the error signal to generate a weighted error signal. The weights may be assigned to the error signal in the portion of the frequency range and a remaining portion of the frequency range according to the configuration. The wireless node may transmit the signal based at least in part on utilizing the weighted error signal to apply digital pre-distortion to the signal. Numerous other aspects are described.
