    摘要： 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.

    摘要： Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an indication that a downlink communication is to be transmitted having tone reservation applied to one or more subcarriers of a downlink channel based at least in part on the downlink channel, the one or more subcarriers having indices associated with a set of verification bits. The UE may decode the downlink communication based at least in part on the tone reservation being applied to the one or more subcarriers and based at least in part on the set of verification bits. Numerous other aspects are described.

    摘要： 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.

    摘要： Methods, systems, and devices for wireless communications are described. A first device may transmit, from a first antenna of a first antenna array of the first device to a second antenna of a second antenna array of a second device, a first set of reference signals. The first device may transmit, from a first plurality of antennas of the first antenna array to a second plurality of antennas of the second antenna array, a second plurality of reference signals. The first device may receive, from the second device, an indication based at least in part on a linear offset and one or more rotational offsets estimated by the second device associated with the first set of reference signals and the second plurality of reference signals. The first device may communicate with the second device using the first antenna array based on the indication.

    摘要： 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.

    摘要： Methods, systems, and devices for wireless communications are described. A receiving device and a transmitting device may utilize index modulation for full-duplex operations. The transmitting device, such as a base station or a user equipment (UE), may define blocks of resource elements (REs) for transmissions. The transmitting device may then transmit a power boosted index modulated signal at a data RE location within a resource allocation and may skip transmitting within the remaining REs of the resource allocation. The transmitting device may indicate the number of REs per RE block to the receiving device (e.g., a UE). The receiving device may use this information to perform energy detection for determining which REs within an RE block include the power boosted index modulated transmission and which REs within the RE block are empty REs. In some cases, the receiving device may use the empty REs for performing noise estimation.
