  • Publication number: 20220255778
    Abstract: Methods, systems, and devices for wireless communications are described. A base station may transmit signaling that configures a wireless device to use a multi-level coding (MLC) procedure to communicate with a base station. Based on receiving the signaling, the wireless device may select a channel quality indicator (CQI) index from a set of CQI indices that are associated with an MLC procedure. In some examples, the wireless device selects the CQI index from a set of CQI indices that includes both bit-interleaved coded modulation (BICM)-based and MLC-based CQI indices. In other examples, the wireless device selects the CQI index from a set of CQI indices that includes solely MLC-based CQI indices. The wireless device may transmit the selected CQI index to the base station. And the base station may select a modulation and coding scheme for subsequent transmissions to the wireless device based on the received CQI index.

  • Publication number: 20220231895
    Abstract: This disclosure provides methods, devices and systems for reducing PAPR in wireless communications. Some implementations more specifically relate to suppressing the amplitudes of a data signal that exceed a threshold amplitude level. The data signal may represent transmit (TX) data associated with a hybrid automatic repeat request (HARQ) process. In some implementations, a transmitting device may detect one or more peaks associated with the data signal. The transmitting device may reduce the amplitudes of the samples associated with the detected peaks to produce the amplitude-suppressed data signal. The transmitting device may further generate peak suppression information indicating the amplitudes of one or more of the samples associated with the peaks. In response to receiving a NACK message, the transmitting device may transmit, to the receiving device, the peak suppression information, one or more coded bits representing the TX data (associated with the HARQ process), or any combination thereof.

  • Publication number: 20220190963
    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.

  • Publication number: 20220190838
    Abstract: Aspects relate to analog-to-digital conversion of an analog signal. The resolution (number of bits) and/or the quantization levels of the analog-to-digital conversion may be configurable. A device may configure its analog-to-digital conversion parameters. For example, a first device may reduce the number of bits for its analog-to-digital converter to reduce power consumption. In this case, the first device may transmit an indication of selected analog-to-digital conversion parameters to a second device that will transmit to the first device. In this way, the second device may take appropriate action, if needed. A device may request another device to use certain analog-to-digital conversion parameters. For example, a first device may determine that a second device should use a larger number of bits for its analog-to-digital conversion process to improve the quality of the communication between the first and second devices.

  • Patent number: 11362694
    Abstract: Aspects relate to reconstructing a received non-linearly distorted (e.g., clipped) signal. A transmitting device may non-linearly distort a signal to be transmitted (e.g., by clipping peaks of the signal). A receiving device uses a signal reconstruction procedure to reconstruct the original signal. For example, the receiving device may estimate the non-linear distortion (e.g., due to clipped peaks) in the received signal by slicing the received signal, and applying a non-linear distortion to (e.g., clipping) the sliced signal using a threshold that corresponds to a threshold (e.g., a clipping threshold) used by the transmitting device. The receiving device may thereby generate a reconstructed signal based on this estimate of the non-linear distortion.
