Abstract: Some examples of the disclosure are directed to methods for application-based spatial refinement in a multi-user communication session including a first electronic device and a second electronic device. While the first electronic device is presenting a three-dimensional environment, the first electronic device receives an input corresponding to a request to move a shared object in the three-dimensional environment. In accordance with a determination that the shared object is an object of a first type, the first electronic device moves the shared object and an avatar of a user in the three-dimensional environment in accordance with the input. In accordance with a determination that the shared object is an object of a second type, different from the first type, and the input is a first type of input, the first electronic device moves the shared object in the three-dimensional environment in accordance with the input, without moving the avatar.

Abstract: Some examples of the disclosure are directed to systems and methods for managing locations of users in a spatial group within a communication session based on the display of shared content in a three-dimensional environment. In some examples, a first electronic device and a second electronic device are in communication within a communication session.

Abstract: A user equipment (UE) communicates with transmission-reception points (TRPs). When the UE generates uplink control information (UCI), it determines a higher layer index (HLI) value to target the UCI to the appropriate TRP. (Possible values of the HLI are associated with the TRPs.) For UCI on Physical Uplink Control Channel (PUCCH), the HLI value may be determined: based on an HLI value configured for a control resource set (CORESET), or for particular Physical Uplink Control Channel (PUCCH) resources; based on UCI type or spatial relation data or an index related to PUCCH resources. For UCI on a configured-grant Physical Uplink Shared Channel (PUSCH), the HLI value may be based on higher layer signals or an indicator relating to channel sounding on spatial relation data. For UCI on MsgA PUSCH in a two-step random access procedure, the HLI value may be based on PUSCH resource unit or PUSCH opportunity.

During a hold phase subsequent to the sample phase, the sample and hold circuit generates an output voltage as a combination of the sampled first and second voltages.

Abstract: Various implementations disclosed herein include devices, systems, and methods that present virtual content based on detecting a reflective object and determining a three-dimensional (3D) position of the reflective object in a physical environment. For example, an example process may include obtaining sensor data (e.g., image, sound, motion, etc.) from a sensor of an electronic device in a physical environment that includes one or more objects. The method may further include detecting a reflective object amongst the one or more objects based on the sensor data. The method may further include determining a 3D position of the reflective object in the physical environment (e.g., where the plane of the mirror is located). The method may further include presenting virtual content in a view of the physical environment. The virtual content may be positioned at a 3D location based on the 3D position of the reflective object.

Abstract: An electronic device displays a first application and a second application along an edge of the display and, while concurrently displaying the first and second applications, detects an edge-swipe gesture. in response, if the location corresponds to a location of a respective application on the display, the respective application is associated with standard edge-swipe gesture criteria, and the edge-swipe gesture meets the standard edge-swipe gesture criteria, the device performs a system operation that includes displaying a system user interface at a portion of the display previously occupied by at least a portion of the first application and at least a portion of the second application; if the location of the edge-swipe gesture corresponds to a location of the respective application, the respective application is associated with enhanced edge-swipe gesture criteria, and the edge-swipe gesture does not meet the enhanced edge-swipe gesture criteria, the device forgoes performing the system operation.

Abstract: While in an inactive state, a user equipment (UE) device transmits a message to a base station. The message indicates the UE device's intent to perform transmission and/or reception of user data with the network during the inactive state. The message may include a portion of the user data and/or a buffer status report. The UE device receives a response message that induces a state transition in the UE device. Different state transitions (e.g., to idle, inactive, legacy inactive, connected) may be induced by different types of response message (e.g., release, release with suspend configuration, resume, setup). One particular type of response message causes the UE to stay in the inactive state and enables subsequent user data transmission/reception in the inactive state. The response message may implicitly (or explicitly) indicate that forwarding of the user data to a core network was successful.

In some implementations, a location-based client can concurrently display map and vehicle information related to a location of the mobile device.

The antenna may include a first dielectric block on a printed circuit, a second dielectric block on the first dielectric block, and a third dielectric block on the second dielectric block. At least the second and third dielectric blocks may have different dielectric constants. The antenna may be fed by one or more feed probes. Each feed probe may include respective conductive via and a conductive patch coupled to the conductive via. The conductive via may extend through the first dielectric block. The conductive patch may be sandwiched between the first and second dielectric blocks. The conductive patch may have a width that configures the conductive patch to form a smooth impedance transition between the conductive via and each of the dielectric blocks despite the different materials used to form the antenna.

Abstract: An exemplary process obtains sensor data for a physical environment, generates a local scene graph for the physical environment based on the sensor data, wherein the local scene graph represents a set of objects and relationships between the objects, matches the local scene graph with a principal scene graph of a set of principal scene graphs, and executes one or more scripted actions involving the objects based on a narrative associated with the matched principal scene graph. In some implementations, the set of principal scene graphs is generated by generating local scene graphs for a plurality of environments, and generating individual scene graphs each representative of local scene graphs.

Abstract: An electronic device may have a display. The display may include an array of pixels formed on a silicon substrate. Display driver circuitry may be formed in a display driver integrated circuit that outputs display data and other control signals for operating the display. An interposer structure may be included in the electronic device. The interposer structure may be attached to the silicon display substrate and may only partially overlap the silicon display substrate. The display driver integrated circuit may be attached to the interposer structure and provide signals to the display pixels through the interposer structure. In another possible arrangement, the display driver integrated circuit may bridge a gap between the silicon display substrate and the flexible printed circuit. The display driver integrated circuit only partially overlaps the silicon display substrate in this arrangement.

Abstract: Systems, apparatuses, and methods for error detection and recovery when streaming data are described. A system includes one or more companion direct memory access (DMA) subsystems for transferring data. When an error is detected for a component of the companion DMA subsystem(s), the operations performed by the other components need to gracefully adapt to this error so that operations face only a minimal disruption. For example, while one or more consumers are still consuming a first frame, a companion router receives an indication of an error for a second frame, causing the companion router to send a router frame abort message to a route manager. In response, the route manager waits until the consumer(s) are consuming the second frame before sending them a frame abort message. The consumer(s) flush their pipeline and transition to an idle state waiting for a third frame after receiving the frame abort message.
