Abstract: 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.

Abstract: Methods, systems, and devices are described for transceiver architecture for millimeter wave wireless communications. A device may include two transceiver chip modules configured to communicate in different frequency ranges. The first transceiver chip module may include a baseband sub-module, a first radio frequency front end (RFFE) component and associated antenna array. The second transceiver chip module may include a second RFFE component and associated antenna array. The second transceiver chip module may be separate from the first transceiver chip module. The second transceiver chip module may be electrically coupled to the baseband sub-module of the first transceiver chip module.

Abstract: 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 math 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.

Abstract: Systems and methods for providing wireless communication impairment correction using non-linear iterative precoding by a transmitter device are disclosed. The transmitter may exploit the non-linear transmit indications, and perform digital non-linear multiple input multiple output (MIMO) precoding of a transmit signal to improve the error vector magnitude (EVM) at the intended receiver device and/or reduce the adjacent channel leakage ratio (ACLR) at the unintended receiver devices. The non-linear transmit indications may comprise amplitude modulation to amplitude modulation (AM-AM) and amplitude modulation to phase modulation (AM-PM) indications. In operation, the non-linear transmit indications may be received from the intended receiver devices or may be measured by the transmitter device.

Abstract: 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.
