  • Publication number: 20220239543
    Abstract: Methods, systems, and devices for wireless communications are described for optimizing index modulated (IM) communications between a user equipment (UE) and a base station. The UE may identify a quantity of subcarriers for IM communications and transmit a message including an indication of the quantity of subcarriers to the base station. In some examples, the UE may transmit an indication of one or more subcarriers to exclude from IM communications. The base station may receive the indication of the quantity of subcarriers and/or the indication of the blacklisted subcarrier(s) and may determine a number of active subcarriers to be used based on at least the indication of the quantity of subcarriers. The base station may transmit an indication of the number of active subcarriers to the UE. The UE may process one or more received IM downlink signals based on the quantity of subcarriers.

  • Publication number: 20220190837
    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.

  • 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.

  • 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: 20220141064
    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit, to a base station, a capability message indicating a capability supporting network-side phase noise compensation. The UE may transmit, to the base station, phase tracking reference signals based on transmitting the capability message. In an example, the phase tracking reference signals may include a UE phase noise component which may be associated with a local oscillator of the UE. The UE may receive, from the base station, a compensated downlink transmission that is compensated based on the UE phase noise component. In generating the compensated downlink transmission, the base station may apply a multiplication factor associated with the estimated UE phase noise component to the compensated downlink transmission.

  • Patent number: 11296735
    Abstract: Methods, systems, and devices for wireless communications are described. A base station may transmit, to each user equipment (UE) of a set of UEs, a different respective set of one or more training parameters for a digital pre-distortion procedure. Some or all of the UEs may determine one or more respective training values based on the one or more training parameters, where the training values from the UEs support the base station computing a set of non-linearity coefficients for the digital pre-distortion procedure. The base station thus may receive training parameters from some or all of the UEs and determine the set of non-linearity coefficients based thereon. The base station use the non-linearity coefficients to perform the digital pre-distortion procedure for one or more downlink transmissions, to one or more UEs of the group of UEs used for training, or to one or more other UEs.

    Abstract: Methods, systems, and devices for wireless communications are described for estimating one or more environmental factors at a first user equipment (UE). The one or more environmental factors may be based on estimates of a Doppler spread and a power delay profile (PDP) taken over a set of subsets of a time period, based on multiple signals received from a second UE or a base station over the time period. The first UE may estimate the Doppler spread and PDP for a channel over each of the set of subsets of the time period, and may combine the Doppler spread over the set of subsets and combine the PDP over the set of subsets. The first UE may use the combined Doppler spread and the combined PDP to determine one or more communication parameters for the channel.
