Abstract: Methods, systems, and devices for wireless communications are described. In a wireless communications system, a first user equipment (UE) may receive a message from a second UE via a set of one or more antennas, where a first symbol period and a second symbol period of the message include a duplicated signal, and the first symbol period is immediately prior to the second symbol period in a time domain. The first UE may calculate a correlation between first data included in the first symbol period and second data included in the second symbol period of the message for each antenna of the set of one or more antennas. In some cases, the first UE may power down at least one radio frequency chain based on the result of the calculated correlation satisfying a threshold value.

Abstract: Methods, systems, and devices for wireless communications are described. In one example, a transmitting device may identify first and second portions of data to include in a data transmission. The transmitting device may encode the second portion by a configuration of a first subset of resource elements. The transmitting device may transmit, via the data transmission, first signals representative of the first portion over the first subset and one or more second signals over a second subset of resource elements. A receiving device may receive the data transmission and may identify that the one or more second signals include content other than data of the data transmission. The receiving device may decode the first signals in order to identify the first portion and the configuration in order to identify the second portion. The receiving device may refrain from decoding the one or more second signals based on the identifying.

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 wireless communications are described. A user equipment (UE) may receive, from a base station, a configuration indicating a set of resources for a reference signal to track an in-phase and quadrature-phase imbalance of the UE. The set of resources may include a first subset of resources for transmitting the reference signal and a second subset of resources for a mirror image signal that is generated during upconversion of the reference signal. The UE may upconvert the reference signal to a set of subcarriers corresponding to the first subset of resources and transmit the upconverted reference signal on the first subset of resources. The base station may receive the reference signal and the mirror image signal and determine a signal adjustment for communications with the UE based on the received reference signal and the received mirror image signal.

Abstract: A device is configured to generate prediction data for the picture, wherein the prediction data for the picture comprises predictions of blocks of the picture based at least in part on one or more previously reconstructed pictures of the video data; generate encoded video data based on the prediction data for the picture, wherein the encoded video data includes transform blocks that comprises transform coefficients; scale bits of the transform coefficients of the transform blocks based on reliability values for bit positions; generate error-corrected encoded video data using the error correction data to perform an error correction operation on the scaled bits of the transform coefficients of the transform blocks; and reconstruct the picture based on the error-corrected encoded video data.

Abstract: Methods, systems, and devices for wireless communication are described. A transmitter device may encode information for a message using a spinal code. The transmitter device may divide the information into sets of bits each including a variable quantity k of bits, and map the sets of bits to symbols to generate a message. The transmitter device may transmit the symbols in an order based on the k values (symbols with smaller k values at the beginning of the message and larger k values at the end). Based on receiving the message, a receiver device may identify the k of each symbol and decode the symbols. The receiver device may identify a partial codeword or determine a likelihood of error associated with the message, which the receiver device may indicate via a feedback message. The transmitter device may retransmit a portion of the message based on the feedback.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for early termination of decoding attempts, including decoding attempts associated with physical downlink control channel (PDCCH) candidates that are encoded using a rateless code. In some aspects, a transmitting device may encode a message using a rateless code associated with a cumulative encoding of various portions of the message, and using a device identifier or group identifier as an input to the encoding. Similarly, a receiving device may receive an encoded signal over candidate resources and may attempt to decode the signal in accordance with the rateless code and using a device identifier or a group identifier as an input to the decoding. As such, intended or non-intended receiving device may be able to evaluate whether to proceed with a decoding attempt or to terminate a decoding attempt at a relatively early stage.

Abstract: Methods, systems, and devices for wireless communications are described. A first wireless device may identify a reference signal sequence (e.g., a demodulation reference signal (DMRS) sequence) based on a cyclic shift associated with a control channel for communications with a second wireless device. For example, the first wireless device may identify the cyclic shift associated with transmitting a message to the second wireless device via the control channel. In another example, the first wireless device may estimate the cyclic shift associated with receiving a message from the second wireless device via the control channel. The first wireless device may then communicate with the second wireless device based on the reference signal sequence. For example, the first wireless device may transmit or receive (e.g., via a shared channel) the reference signal sequence to or from the second wireless device.
