Abrégé

Examples are described of segmenting an image into image regions based on depicted categories of objects, and for refining the image regions semantically. For example, a system can determine that a first image region in an image depicts a first category of object. The system can generate a color distance map of the first image region that maps color distance values to each pixel in the first image region. A color distance value quantifies a difference between a color value of a pixel in the first image region and a color value of a sample pixel in a second image region in the image. The system can process the image based on a refined variant of the first image region that is refined based on the color distance map, for instance by removing pixels from the first image region whose color distances fall below a color distance threshold.

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.

Abrégé

Methods, systems, and devices for wireless communications are described. Generally, the described techniques at a user equipment (UE) provide for indicating multiple beams to a base station for communications with the base station after detecting a beam failure. Using these techniques, the UE may rely on multi-beam operation to recover communications with the base station. The UE may transmit a random-access preamble indicating a first beam for communications with the base station, and the UE may transmit a control element in a data channel indicating a second beam for communications with the base station. In some cases, the messages used to carry the indications of the multiple beams may be based on a type of random-access procedure used to recover communications (e.g., a contention-based random-access (CBRA) procedure, a contention-free random-access (CFRA) procedure, or a two-step random-access procedure).

Abrégé

A digital phase-frequency detector characterizes a delay between two input clock signals using a ring oscillator. A cycle count of a ring oscillator signal circulating through a loop in the ring oscillator during the delay provides a coarse measurement of the delay. A phase of the ring oscillator signal in the loop at the end of the delay provides a fine measurement of the delay. A digital phase-locked loop may control an oscillation frequency of a digitally-controlled oscillator responsive to the fine measurement of the delay and control a division within a clock divider responsive to the coarse measurement of the delay.

Abrégé

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.

Abrégé

Aspects relate to analog-to-digital conversion of an analog signal. The resolution 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. 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.

Abrégé

A user equipment (UE) uses conditional reconfiguration during positioning to improve the positioning performance. The UE receives conditional reconfiguration information from a serving base station, which includes a list one or more candidate target base stations and their associated resources for handover. During a positioning session, the UE receives assistance data and determines a target base station for handover based on the list of candidate target base stations and the assistance data. The UE, for example, may select a candidate target base station for handover during the positioning session to minimize the number of measurements gaps that are required for positioning measurements, or to increase bandwidth or minimize self-interference. Where timing advance measurements are requested, the UE may select a candidate target base station based on sub-carrier spacing to improve measurement resolution.

Abrégé

Systems and methods for variable stride counting (502, 506, 510) for timed-triggers in a radio frequency front end (RFFE) bus modify how a master clock controls counters in slaves. In particular, instead of having the master clock change a counter at a slave device on a one-to-one clock tick-to-counter change, exemplary aspects of the present disclosure contemplate allowing a bus ownership master (BOM) to select a stride size (502, 506, 510) wherein each clock tick causes the counter to change by the size of the stride. Clock ticks are then sent less frequently over the clock line of the RFFE bus. In this fashion, fewer clock ticks are required to change the counter to the trigger event.

In one aspect, resource selection may be performed where single frequency full-duplex (SFFD) UEs are present in a V2X system. Signaling and procedures may enable the coexistence of half-duplex (HD) and SFFD-capable UEs. Based on the resource reservation information obtained from other UEs, the SFFD UE may determine which among the reserved time-frequency resources is amenable for performing the SFFD operation. In one aspect, the time-frequency resources chosen for SFFD may partially or fully overlap with the reserved time-frequency resources, based on the self-interference cancellation capability of the SFFD UE, the RSRP, and/or the RSSI on the reserved time-frequency resources. Accordingly, the full-duplex capability of an SFFD-capable UE may be leveraged, and spectral efficiency improved.

Abrégé

Aspects of the present disclosure provide apparatus, methods, processing systems, and computer readable mediums for non-standalone sidelink discovery. A user equipment (UE) may be capable to operate in two or more separate frequency ranges. In one of the separate frequency ranges, sidelink discovery may require a burdensome overhead due to the nature of beam forming at high frequency ranges. Communications in another lower frequency range may signal to aid the discovery, thus reducing the overhead. For example, the UEs may use the low frequency communication to perform a beam alignment and discovery with lower signaling overhead. In addition, the UE may signal the capability in a first frequency range using signatures or indications in a communication in a second frequency range. For example, the UE may use FR2 to signal FR1 capability, such as using beam pilots as signatures to indicate FR1 capability.

Abrégé

This disclosure provides methods, devices and systems for pre-compensation of downlink communication based on a transmission of a request for the pre-compensation from a user equipment (UE). For example, the UE may determine an impairment at the UE that has a greater severity (a greater impact on downlink communication) or is associated with a greater amount of resources for processing relative to a remainder of a set of impairments that is experienced at the UE and the UE may transmit a request for pre-compensation of the impairment by a base station. The base station may transmit feedback to the UE indicating a confirmation of pre-compensation for the impairment by the base station or to deferment of compensation for the impairment back to the UE. If the base station acknowledges pre-compensation for the impairment, the base station may pre-compensate a downlink transmission to the UE for the impairment.

Techniques are described herein for processing video data using a history-based rice parameter derivation. For instance, a process can include obtaining a transform block including a plurality of samples. One or more parameters (e.g., rice parameters) can be determined for the plurality of samples by analyzing a local neighborhood of a current sample of the plurality of samples and determining that a number of neighboring transform coefficients of the current sample is less than a threshold amount. A historic parameter value (e.g., a historic rice parameter value) determined from one or more previously decoded transform blocks can be obtained and, based at least in part on the historic parameter value, a parameter (e.g., a rice parameter) can be determined for the current sample. The current sample can be decoded based on the determined parameter for the current sample.

Abrégé

Disclosed are techniques for wireless communication. In some aspects, a base station (BS) may determine a first planned transmit beam configuration of the first BS. The BS may obtain a second planned transmit beam configuration of a second BS. The BS may determine that a first planned transmit beam of the first planned transmit beam configuration will interfere with a second planned transmit beam of the second planned transmit beam configuration. The BS may modify the first planned transmit beam, the second planned transmit beam, or both, based on the interference determination.

Abrégé

Techniques are described herein for processing video data using a neural network system. For instance, a process can include generating, by a first convolutional layer of an encoder sub-network of the neural network system, output values associated with a luminance channel of a frame. The process can include generating, by a second convolutional layer of the encoder sub-network, output values associated with at least one chrominance channel of the frame. The process can include generating, by a third convolutional layer based on the output values associated with the luminance channel of the frame and the output values associated with the at least one chrominance channel of the frame, a combined representation of the frame. The process can further include generating encoded video data based on the combined representation of the frame.
