Abstract: Various techniques are presented to improve phase tracking reference signal (PTRS) performance with respect to very high frequency communications. According to some embodiments, increased power boosting may be applied to improve PTRS performance, while still keeping power spectral density (PSD) within ETSI Broadband Radio Access Networks (BRAN) limits. In some cases, the power boosting may be semi-static and/or dynamic. In other embodiments, the improved performance may be achieved by dynamically changing time and/or frequency density of the PTRS. In other embodiments, a multi-port configuration may be used for the downlink PTRS. In other embodiments, one or more PTRS configurations may be determined per SCS and/or frequency band, e.g., based on traffic type, channel priority, parameters signaled in the slot format indication (SFI), etc. In other embodiments, common phase error (CPE) estimates may be obtained for those OFDM symbols without PTRS by interpolating the available PTRS estimates in the time domain.

Abstract: The subject technology receives assessment values determined by a first machine learning model deployed on a client electronic device, the assessment values being indicative of classifications of input data and the assessment values being associated with constraint data that comprises a probability distribution of the assessment values with respect to the classifications of the input data. The subject technology applies the assessment values determined by the first machine learning model to a second machine learning model to determine the classifications of the input data. The subject technology determines whether accuracies of the classifications determined by the second machine learning model conform with the probability distribution for corresponding assessment values determined by the first machine learning model.

Abstract: Printed circuit boards (PCB) used to mechanically and electrically connect electrical components within an electronic device. Thin printed circuit boards (PCB) may be desirable to manufacturers and users of electronic devices. Accordingly, a process for manufacturing a printed circuit board may involve manufacturing a thin bilayer dielectric. The process may involve applying a first non-conductive layer to a metal substrate, and curing the first non-conductive layer to a C-stage resin layer that is fully cross-linked layer in a clean environment. In turn, a B-stage layer that is partially cured may be applied to the C-stage resin layer. Using a hot press, one or more metal traces may be pressed onto the B-stage layer. The B-stage resin layer may be fully cross-linked and integrated with the C-stage resin layer after lamination of the one or more metal traces and the B-stage resin layer.

Abstract: An apparatus may receive a media access control (MAC) control element (CE) from a base station (BS) indicating a secondary cell (SCell) to be activated in an unlicensed band. The apparatus may initiate a timer with an end value in response to receiving the MAC CE and may further adjust a radio-frequency (RF) chain from a first state to a second state corresponding to the SCell to be activated. The apparatus may determine, based on measurements of one or more synchronization signal blocks (SSBs) transmitted from the BS indicating one or more listen before talk (LBT) failures corresponding to the SCell, one or more failed SSB transmissions corresponding to the SCell. Accordingly, the apparatus may readjust, in response to expiry of the timer, the RF chain from the second state to the first state and receive one or more additional SSBs in the first state.

Abstract: In some implementations initially training a first neural network includes inputting the training inputs and corresponding training labels into the first neural network to produce output labels, comparing the output labels to the corresponding training labels using a second neural network that learns and applies a comparison metric, and adjusting parameters of the first neural network based on the comparing. The device then inputs additional inputs into the first neural network to produce additional output labels and corresponding confidence values from the second neural network. The device selects, based on the confidence values, an automatically-labeled training set of data including a subset of the additional inputs and a corresponding subset of the additional output labels. During a second training stage, the device trains the first neural network and the second neural network using the automatically-labeled training set of data.

Abstract: In one implementation, a method of resolving focal conflict in a computer-generated reality (CGR) environment is performed by a device including a processor, non-transitory memory, an image sensor, and a display. The method includes capturing, using the image sensor, an image of a scene including a real object in a particular direction at a first distance from the device. The method includes displaying, on the display, a CGR environment including a virtual object in the particular direction at a second distance from the device. In accordance with a determination that the second distance is less than the first distance, the CGR environment includes the virtual object overlaid on the scene. In accordance with a determination that the second distance is greater than the first distance, the CGR environment includes the virtual object with an obfuscation area that obfuscates at least a portion of the real object within the obfuscation area.

Abstract: Methods and apparatus are disclosed for a UE and its serving base station in 5G NR systems to signal channel scan or channel sensing to allow channel occupancy time (COT) sharing before transmissions. The COT sharing may be initiated by the base station or by the UE by asserting a CCA indication to enable channel sensing by a UE or base station, respectively. When the UE receives and decodes the asserted CCA indication during downlink transmission, the UE may perform channel sensing during a short interframe space (SIFS) between the downlink transmission and a scheduled uplink transmission. When the UE detects that the sensed RF energy across an intended transmission band is greater than an energy detect threshold, the UE may refrain from transmitting during the scheduled uplink transmission. Otherwise or when the CCA indication is de-asserted, the UE may transmit during the scheduled uplink transmission without performing channel sensing.

In some implementations, the method includes generating second image data by modifying the first image data based on a function of the current ambient light condition and a threshold ambient light condition detected during enrollment. In some implementations, the method includes displaying the second image data on the display.

Abstract: The subject technology provides for stroke based control of handwriting input. The disclosed stroke based control facilitates selection, copy, paste, search, data detection and other operations for handwritten electronic text. The selection of text represented by handwritten strokes can be performed without drawing a lasso or other loop around the desired text, by using known boundaries of words and phrases in stroke space. Selection of text in this manner allows copy and/or paste of recognized words or phrases, of images of the words or phrases, and/or of the strokes themselves. Boundaries, in stroke space, of actionable data represented by the strokes can also allow action options to be provided when a user interacts with strokes within the boundary.
