Abstract: Methods, systems, and devices for wireless communications are described. In some cases, a device may perform a first analog to digital conversion (ADC) to generate a first set of samples of a wireless signal, and may attenuate the signal according to a dynamic range. The device may then perform a second ADC on the attenuated signal to generate a second set of samples, amplify the second set of samples, output whichever set of samples is greater. In some other cases, the second ADC may determine to attenuate the wireless signal based on an input power, amplify the signal, and output the amplified samples. In some other cases, the wireless device may determine an estimated input power of the wireless signal at a number of antenna elements. The device may then determine an adjustment to gain states of low-noise amplifiers (LNA) associated with each of the number of antenna elements.

Abstract: Methods, systems, and devices for wireless communications are described. A transmitting (Tx) device transmits, to a receiving (Rx) device, a control message indicating a location of one or more noise spurs associated with wireless communications performed by the Tx device using a set of resources, where the location includes a frequency location of the one or more noise spurs in the frequency domain. The Tx device then generates a data message to be communicated using the set of resources associated with the one or more noise spurs based on transmitting the control message, and transmits the generated data message to the Rx device using the set of resources associated with the one or more noise spurs. By indicating the location of the noise spurs, the Rx device may be more able to more efficiently identify and address (e.g., filter out, ignore) the noise spurs within the data message.

Abstract: Methods, systems, and devices for wireless communications are described. For example, a transmitting wireless device, such as a user equipment or a base station, may apply a first set of digital pre-distortion (DPD) coefficients to a plurality of antenna elements to form a first transmit beam. The wireless device may determine to switch from using the first transmit beam to using a second transmit beam that is different from the first transmit beam and may apply a second set of DPD coefficients to the plurality of antenna elements to form the second transmit beam, where the second set of DPD coefficients is different from the first set of DPD coefficients. The wireless device may transmit signaling using the second transmit beam based at least in part on applying the second set of DPD coefficients.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may monitor sets of decoding candidates over a search space in each monitoring occasion to detect downlink control transmissions. Such a monitoring process may be resource intensive. To reduce the processing power involved in monitoring the control channel, a UE may measure resources associated with the downlink control channel to obtain a quality metric. The UE may compare the quality metric to one or more thresholds and may perform a decoding process on a set of configured decoding candidates for the downlink control channel based on the comparing. In some cases, if the channel quality is relatively good, the UE may perform a list decoding process using a list size less than a maximum list size or may perform partial data tone processing to reduce the processing complexity for some of the decoding candidates.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may receive an uplink transmission from a user equipment (UE) over a wireless channel and measure a post-digital post-distortion (post-DPOD) signal-to-noise ratio (SNR) of the uplink transmission. The base station may generate a power output back-off indication for the UE according to the post-DPOD SNR and a change in a post-DPOD noise level of the transmission between a non-linear distortion noise component and a thermal noise component. The base station may transmit the power output back-off indication and a downlink transmission to the UE. In response, the base station may receive an uplink transmission from the UE over the wireless channel. The uplink transmission may be based on the power output back-off indication, a signal quality metric of the downlink transmission, or both.

Abstract: Methods, systems, and devices for wireless communications are described. For instance, a first device may transmit a reference signal to a second device and the second device may measure self-interference at the second device. In a first example, the second device may transmit an indication of channel state information to the first device along with an interference report including a measure of the self-interference, which the first device may use to determine an MCS and/or a rank. In a second example, the second device may determine an MCS and/or rank based on measuring the self-interference. In some examples, the second device may transmit a first indication of the MCS and/or rank determined based on measuring the self-interference to the first device along with a second indication that the MCS and/or rank is associated with full-duplex communications at the second device.

Abstract: Certain aspects of the present disclosure provide techniques for training a digital pre-distorter (DPD) using real-time over-the-air transmissions and receptions by a user equipment (UE). A method for training the DPD generally includes transmitting a signal, generated by a transmitter front end, via a first port; sampling the signal, received over the air, at a second port; performing signal processing cleaning (e.g., synchronization, linear over-the-air channel estimation and equalization); calculating coefficients for a DPD; and configuring the DPD with the coefficients, for use in digitally pre-distorting sub sequent transmissions.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station, one or more downlink grants scheduling one or more corresponding downlink transmissions from the base station to the UE. In some examples, the UE may enter a state of sleep prior to receiving the one or more downlink transmissions. In such examples, the UE may wake up from the state of sleep at a first time that is at least a threshold period of time before a second time corresponding to a beginning of the one or more downlink transmissions. After waking up from the state of sleep, the UE may activate a notch filter and use the activated notch filter to filter a spur generated at the UE. The UE may receive the one or more downlink transmissions with improved reliability based on activating the notch filter.
