摘要： A user equipment (UE) includes a transmit chain that includes multiple radio frequency transmitters, multiple power amplifiers and a front end (FE) through which signals are transmitted. To achieve a high power UE solution, aspects of the disclosure selectively combine two or more power amplifier outputs based on an expected power output of the UE. To synchronously combine the outputs, an output feedback signal from a feedback receiver is used to adjust a delay and a phase of one or more signals associated with the power amplifiers.

摘要： A transceiver in a wireless device supporting carrier aggregation may include a correction module to generate a correction signal to attenuate intermodulation distortion associated with a first transmitted communication signal. In one embodiment, the correction signal may be added to the first transmitted communication signal (a victim signal) to reduce the intermodulation distortion caused by a second transmitted communication signal (an aggressor signal). The correction signal may be generated based on the aggressor signal. In another embodiment, the correction signal may equalize or pre-distort the first transmitted communication signal.

摘要： A wireless device with built-in self test (BIST) capability for testing/calibrating transmit and receive circuits is disclosed. In an exemplary design, an apparatus (e.g., a wireless device or an integrated circuit) includes a first circuit and a second circuit. The first circuit (e.g., a transmitter or a mixer) provides a test signal to at least one transmit path. The test signal is electro-magnetically coupled from the output of the at least one transmit path to a test signal line. For example, the test signal may be provided from the at least one transmit path via at least one antenna feed line to at least one antenna element and may be electro-magnetically coupled from the at least one antenna feed line to the test signal line. The second circuit (e.g., a buffer, a receiver, or a mixer) processes a received test signal from the test signal line.

摘要： An in-band full-duplex transceiver includes a self-interference mixer for up-converting an adjusted digital baseband signal into an up-converted self-interference cancellation signal. The adjusted digital baseband signal has a phase opposite to a phase for a leakage signal from a leakage path for the transceiver. Similarly, the adjusted digital baseband signal has a magnitude matching a magnitude for the leakage signal. Given this phasing and magnitude for the up-converted self-interference signal, it substantially cancels the leakage signal when added with a received signal contaminated by the leakage signal.

摘要： Systems and methods for providing indications about the TX RF non-linear impairments are disclosed. In accordance with some implementations, a first device (UE or base station) estimates EVM indications for the signal and determines if the EVM indications is above a threshold. The first device may transmit the estimated TX non-linearity indications such as AM-AM, AM-PM, Volterra coefficients, and/or other performance metrics to a second device, that transmitted the signal, when it is determined that the EVM indications is above the threshold. Systems and methods for wireless communication impairment correction are also disclosed wherein, in accordance with some implementations, a first device receives estimated TX non-linearity indications such as AM-AM, AM-PM, and/or Volterra coefficients from a second device and performs non-linear correction of a transmit signal for the second receiver device based at least in part on the EVM indications. Other aspects, embodiments, and features are also claimed and described.

摘要： An apparatus and method for cancelling and/or attenuating one or more signal impairments included within a transmitted RF signal is disclosed. In at least one exemplary embodiment, a baseband signal is generated based, at least in part, on a predicted impairment signal subtracted from a desired baseband signal. An impairment detection signal may be generated by multiplying the predicted impairment signal by the baseband signal. The predicted impairment signal may be adjusted based, at least in part, on the impairment detection signal.
