    Abstract: A bit-widths determination method selects bit-widths for mixed-precision neural network computing on a target hardware platform. An activation quantization sensitivity (AQS) value is calculated for each convolution layer in a neural network. The AQS value indicates the sensitivity of convolution output to quantized convolution input. One or more convolution layers are grouped into a quantization group, which is to be executed by a corresponding set of target hardware. A group AQS value is calculated for each quantization group based on the AQS values of the convolution layers in the quantization group. Then bit-widths supported by the target hardware platform are selected for the corresponding quantization groups. The bit-widths are selected to optimize, under a given constraint, a sensitivity metric that is calculated based on each quantization group's group AQS value.

    Abstract: Apparatus and methods are provided for robust front end selection control. In one novel aspect, multi-stage head selection is provided. In one embodiment, the UE monitors one or more head-selection triggers, performs a UE Rx wide beam measurement to select at least one deactivated head as at least one standby head based on one or more coarse-beam selection criteria upon detecting at least one head-selection trigger, performs a UE Rx fine beam selection on the active head and the selected standby head, and switches the standby head as the active head based on a result of the fine Rx beam selection and head selection criteria. One or more operations are used for the multi-stage head selection, including multi-head operation, multi-CC measurement, and joint RRM and head selection operation.

    Abstract: Apparatus and methods are provided for inter-DU inter-cell cell switch with beam management. In one novel aspect, the UE receives a cell switch command, performs RLC reestablishment and MAC reset, sends a PDCP status report to indicate one or more PDCP protocol data units (PDUs) failed for a downlink (DL) or UL data transfer to the source cell for unacknowledged mode (UM) or acknowledge mode (AM) radio bearers, and performs a UE self-detected PDCP retransmission for UL data transfer when the UE detects one or more source-failed UL PDCP PDUs. The PDCP entity performs PDCP retransmission to the target cell. In one embodiment, the RLC entity identifies source-failed PDUs. In another embodiment, UE sends the pending RLC PDUs the PDCP entity and the PDCP entity identifies the source-failed PDUs. In one embodiment, UE triggers, compiles, and sends PDCP status report to the target cell.

    Abstract: Examples pertaining to user equipment (UE) handling of forbidden tracking area identifier (TAI) list information elements (IEs) in an Evolved Packet System (EPS) SERVICE ACCEPT message in mobile communications are described. A user equipment (UE) transmits a CONTROL PLANE SERVICE REQUEST message to an EPS network node of a wireless network. In response, the UE receives a SERVICE ACCEPT message from the EPS network node. The SERVICE ACCEPT message includes either or both of the following: (i) one or more forbidden tracking area identifiers (TAIs) for a list of “forbidden tracking areas for roaming” information element (IE); and (ii) one or more forbidden TAIs for a list of “forbidden tracking areas for regional provision of service” IE.

    Abstract: The techniques described herein relate to methods, apparatus, and computer readable media configured to encode and/or decode video data. Immersive media data includes a set of one or more tracks, each track comprising associated immersive media data corresponding to an associated spatial portion of immersive media content and metadata specifying a six degree of freedom (6DoF) viewing region in the immersive media content, wherein the metadata comprises viewing region type data indicating a type of the viewing region. An encoding and/or decoding operation is performed based on the set of one or more tracks and the viewing region metadata to generate encoded and/or decoded immersive media data. The viewing region type data can be specified by a data structure attribute of the metadata specifying a viewing region and/or by an attribute of the metadata specifying a viewing region.
