Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a transceiver chain may receive, using a downconverter tuned by at least one local oscillator, transmit signals that are modulated using a modulation bandwidth and that span a total bandwidth greater than or equal to the modulation bandwidth. The at least one local oscillator may cover a first fraction of the total bandwidth. The transceiver chain may receive, using at least one analog-to-digital converter, input from the downconverter, and may output a first digital signal based at least in part on the input and sampling at the first fraction of the total bandwidth. The transceiver chain may determine an error associated with the transmit signals based at least in part on the first digital signal, and may perform digital pre-distortion on new signals based at least in part on the error. Numerous other aspects are described.

Abstract: Certain aspects of the present disclosure provide systems and methods for performing a power amplifier characterization. One example method generally includes determining, by a user equipment, if a condition associated with a power amplifier characterization is met. In certain aspects, the method includes determining, by the user equipment, a calibration gap after the condition is met. The method also includes performing, by the user equipment, the power amplifier characterization of the one or more power amplifiers of the user equipment during the calibration gap.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for power amplifier control. A power amplifier network includes a first path comprising a first power amplifier. The power amplifier network further includes a second path comprising a second power amplifier. The power amplifier network further includes a common input path to both the first path and the second path. The power amplifier network further includes a first power control network for controlling a first signal applied to the first power amplifier. The power amplifier network further includes a second power control network for controlling a second signal applied to the second power amplifier, wherein the first power control network is different from the second power control network.
