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 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.

Abstract: Methods, systems, and devices for wireless communications are described. A first wireless device may transmit, to a second wireless device, a first indication of a capability to selectively configure activation states for a set of antenna elements of an antenna array of the first wireless device, and of parameter values that indicate a structure of the antenna array. The first wireless device may then receive, from the second wireless device in response to the transmitted first indication, a second indication for the first wireless device to modify an activation state of one or more antenna elements of the set of antenna elements. The first wireless device may subsequently identify the activation state of the one or more antenna elements based on the received second indication, and communicate with the second wireless device using the antenna array according to the identified activation state of the one or more antenna elements.

Abstract: The present disclosure involves determining base station (BS) beams for communicating between a UE and the BS. The BS may use sensor data or beam management reporting history to assist with determining one or more appropriate beams. The sensor data may include camera images, radar data, or lidar data, and be used to model the cell environment served by the BS. The BS may obtain reporting data from multiple UEs over time indicating the quality of beams received by the UEs at various locations in the cell environment and model the cell environment based on the reporting data. The BS may associate beams with possible UE locations within the cell environment and use the associations to determine beams for communicating with a UE after determining the UE's location.

Abstract: Methods, systems, and devices for latency minimization in wireless communications employing multi-level coding and multi-level sequential demodulation and decoding are described. A user equipment (UE) receive a set of codeblock groups in a first time period. Each codeblock group jointly sharing same channel resources may be associated with a respective decoding level of a set of decoding levels. The UE may determine a first outcome for a first codeblock group and a second outcome for a second codeblock group. The UE may then transmit a feedback message that is based on the first outcome and the second outcome. In case that the feedback message indicates that the first outcome or the second outcome is a failed decoding procedure, the UE may receive, in a second time period, a retransmission of all the codeblock groups. These retransmissions may continue on additional time periods until all related codeblock groups are successfully decoded.

Abstract: Methods, systems, and devices for wireless communications employing multi-level coding with set partitioning on transmitting side and multi-level sequential decoding on the receiving side for latency minimization are described. In some systems, a transmitting device may transmit a code block group (CBG) to a receiving device including a first set of code blocks associated with a first decoding level and a second set of code blocks associated with a second decoding level. The receiving device may unsuccessfully decode one or more code blocks of the first set or the second set of code blocks and transmit a feedback message to the transmitting device. The transmitting device may determine that the data to be communicated via the CBG is latency-sensitive data and, as such, determine to retransmit both the first set and the second set of code blocks to the receiving device in response to receiving the feedback message.

Abstract: A wireless communication device is described. The wireless communication device includes a receiver. The receiver is configured to determine a time-domain sample of a single carrier based on a received signal. The receiver is also configured to determine an estimated value based on the time-domain sample. The receiver is further configured to perform slicing based on the estimated value to produce a sliced value. The receiver is additionally configured to adapt a frequency-domain coefficient based on the estimated value and the sliced value. The receiver is also configured to perform channel equalization based on the frequency-domain coefficient.

Abstract: Methods, systems, and devices for wireless communications are described. A wireless device may receive, using a first receive port, a first signal within a first frequency band, where the first receive port may be associated with a first receive beam. The wireless device may also receive, using a second receive port, a second signal within the first frequency band concurrently with receiving the first signal, where the second receive port may be associated with a second receive beam. After receiving the first and second signals, the wireless device may process both signals. Processing the signals may include decoding both of the signals, measuring both of the signals, and/or decoding one of the signals and measuring the other of the signals. To support concurrent reception over multiple receive beams within a single frequency band, the wireless device may employ an idle antenna panel and corresponding receive ports.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may determine a set of groups of layers relating to a set of transport blocks (TBs) or a set of code division multiplexing (CDM) groups. The UE may group the layers such that the layers in each group have a minimal difference in signal-to-interference-plus-noise ratio (SINR) between the layers. The UE may select a different demodulation reference signal (DMRS) configuration for each of the set of groups of layers based on maximizing a communication efficiency metric for each group of layers. The UE may transmit an indication of the selected DMRS configurations for each group of layers to a base station via a field in a report. The base station may accordingly determine a DMRS configuration for each group of layers based on the DMRS configurations indicated by the UE.
