Abstract: Methods, systems, and devices for wireless communications are described. A transmitting device or a receiving device may indicate support for crest factor reduction (CFR) techniques using clipping and mirroring. The transmitting device may indicate a clipping level and a mirroring level for a CFR function. The transmitting device may generate a waveform in accordance with the CFR function and may transmit the waveform to the receiving device. The receiving device may monitor the waveform to detect one or more mirrored portions of the waveform. The receiving device may invert the one or more mirrored portions of the waveform over the mirroring level to restore and decode the waveform.

Abstract: This disclosure provides systems, methods, and devices for wireless communication that support signaling of network entities' phase noise inter-carrier interference (ICI) order for reducing user equipment (UE) phase noise cancelation complexity. In a first aspect, a method of wireless communication includes obtaining a power spectral density (PSD) measurement of a phase noise mask of a network entity prior to deployment in the field. The network entity, after deployment, measures an integrated residual PSD measurement per candidate phase noise bandwidth size and transmits these integrated residual PSD measurements to a UE. The UE may then use the integrated residual PSD measurements to estimate phase noise for cancelation from network entity transmissions. Other aspects and features are also claimed and described.

Abstract: This disclosure provides systems, methods, and devices for wireless communication that support noise indicator intermediated signal demodulation. An apparatus for wireless communication may include a communication interface configured to receive a noise indicator that indicates a transmitter noise associated with a transmitter. Additionally, the apparatus may include a processor system configured to demodulate, based on a noise covariance matrix, a signal received from the transmitter. The noise covariance matrix may be based on the noise indicator.

Abstract: A device is configured to obtain, from a transmitting device, error correction data that provides error correction information and is generated based on encoded video data of one or more blocks of a picture of the video data; generate prediction data for the picture using one or more coding tools not used for generating the encoded video data, wherein the prediction data for the picture comprises predictions of the blocks based at least in part on previously reconstructed pictures; generate encoded video data based on the prediction data for the second picture; generate error-corrected encoded video data using the error correction data to perform an error correction operation on the encoded video data; and perform a reconstruction operation that reconstructs the blocks of the picture based on the error-corrected encoded video data, wherein the reconstruction operation is controlled by the values of one or more parameters.

Abstract: Methods, systems, and devices for wireless communication are described. A transmitting device may determine reconstruction information for a time-domain signal and may transmit the reconstruction information with the time-domain signal to a receiving device. The transmitting device may generate the reconstruction information based on estimates of how the receiving device may process the time-domain signal. For example, the transmitting device may apply a channel estimate to samples of the time-domain signal, and further perform clipping and quantization of the samples based on an estimated dynamic analog-to-digital converter (ADC) resolution of the receiving device. The transmitting device may generate the reconstruction information (e.g., using machine learning or other techniques) based on samples having the channel estimate applied and the clipped and quantized samples. The receiving device may process the received time-domain signal and use the reconstruction information to reconstruct the processed time-domain signal.

Abstract: Methods, systems, and devices for wireless communications are described. Cyclic redundancy check (CRC) bits may be appended to a set of information bits on a per-group basis prior to encoding using an error correcting code. The amount of CRC bits appended to each group of information bits may be based on the priority of the group of information bits. For example, the priority may be based on the type of information conveyed by the group of information bits. For example, for a video stream, information bits conveying low frequency information may have a higher priority than information bits conveying high frequency information, as the low frequency bits may be more important to user perception/experience of the video. The transmitting device and the receiving device may negotiate the CRC configuration (e.g., the CRC bits per-group and the locations of the groups) so that the receiving device can verify the information bits.

Abstract: Methods, systems, and devices for wireless communications are described. A transmitting device may encode a set of bits to transmit to a receiving device based on a repetition factor. The transmitting device may map, based on the repetition factor, the set of encoded bits to a subset of subcarriers such as adjacent subcarriers of a set of subcarriers. The transmitting device may generate a signal including the set of encoded bits based on the mapping, and transmit the generated signal to the receiving device. The receiving device may receive a modulated signal from the transmitting device, and identify, based on a repetition factor, a subset of subcarriers including adjacent subcarriers of a set of subcarriers associated with the modulated signal. The receiving device may average the subset of subcarriers including the adjacent subcarriers, and demodulate the modulated signal in accordance with the averaged subset of subcarriers including the adjacent subcarriers.

Abstract: Methods, systems, and devices for wireless communication are described for one or more aspects of dynamically configuring an analog-to-digital converter (ADC). A user equipment (UE) may determine a set of supported ADC resolution sizes including one or more dynamically configurable bit quantities. The UE may transmit a capability message including an indication of the set of ADC resolution sizes to a base station. The UE may indicate, to the base station, a power consumption factor or a table of signal-to-quantization noise ratios (SQNR) per bit quantity supported by the UE's ADC. In some cases, the base station may enable, based on the set of ADC resolution sizes, clipping of a power amplifier and one or more associated precoding parameters, and may indicate the precoding parameters to the UE. The UE may select an ADC resolution size for processing received messages.
