Abstract: Methods and apparatus of for video coding using sub-block based affine mode are disclosed. In one method, if affine fallback is used or the control-point motion vectors are the same, the sub-block based affine mode is disabled in order to reduce computational complexity. According to another method for video coding using a coding tool belonging to a coding tool group comprising Prediction Refinement with Optical Flow (PROF) and Bi-Directional Optical Flow (BDOF), predictor refinement is derived for pixels of a target subblock of the current block, where a step to derive the predictor refinement comprises to derive gradients for the pixels of the target subblock of the current block and to right-shift the first gradients by a common shift.

Abstract: Aspects of the disclosure provide a frame processor for processing frames with aliasing artifacts. For example, the frame processor can include a super-resolution (SR) and anti-aliasing (AA) engine and an attention reference frame generator coupled to the SR and AA engine. The SR and AA engine can be configured to enhance resolution and remove aliasing artifacts of a frame to generate a first high-resolution frame with aliasing artifacts and a second high-resolution frame with aliasing artifacts removed. The attention reference frame generator can be configured to generate an attention reference frame based on the first high-resolution frame and the second high-resolution frame.

Abstract: A method for UE route selection policy (URSP) rule matching enhancement for MA PDU session with 4G PDN leg is proposed. When an application is executed, the upper layer of a UE sends the application information to URSP entity for matching a URSP rule. The UE selects and evaluates a route selection descriptor (RSD) from a list of RSDs of a selected URSP rule to be matched with a PDU session. In one example, the PDU session is an MA PDU session with a 3GPP EPS/PDN leg (PDN connection established as user plane resources of the MA PDU session). The UE finds the traffic descriptor in a selected URSP rule matching the application and an existing MA PDU session/PDN connection matching an RSD of the selected URSP rule, when the UE-requested PDN parameters of the PDN connection matches with the RSD of the selected URSP rule.

Abstract: Various solutions for supporting an advanced mobile communication system with enhanced channel designs are described. An apparatus may select a first number of resource blocks (RBs) from a second number of RBs on a physical broadcast channel (PBCH) in an event that the apparatus is operating in a frequency band with a transmission bandwidth less than a threshold. Then, the apparatus may perform a PBCH transmission to a user equipment (UE) based on the first number of RBs.

Abstract: Apparatus and methods are provided for thermal throttling for UE configured with multi-panel transceiving on FR2. In one novel aspect, the UE prioritizes throttling actions based on signal qualities of each transceiving panel. In one embodiment, the switching to the target panel from the active panel is selected as the highest priority throttling action when the signal quality of the target panel is similar to the active panel. In another embodiment, the UE further determines if the quality of the target panel is sufficient to support mmW transceiving before switching to the target panel. In one embodiment, the UE reduces one or more antennae of an active panel when the signal quality difference between the active panel and the target panel is bigger than a predefined gap threshold.

Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The UE receives, from a source cell, a conditional handover (CHO) command configuring the UE to perform a CHO procedure to handover to a target cell in response to satisfying a CHO condition. The UE receives, from the source cell after receiving the CHO command, a handover (HO) command configuring the UE to perform a HO procedure to handover to the target cell. The UE determines whether the UE has started the CHO procedure prior to receiving the HO command. The UE, in response to determining that the UE has started the CHO procedure prior to receiving the HO command, discards the HO command and continues with the CHO procedure.

Abstract: A depth estimation from focus method and system includes receiving input image data containing focus information, generating an intermediate attention map by an AI model, normalizing the intermediate attention map into a depth attention map via a normalization function, and deriving expected depth values for the input image data containing focus information from the depth attention map. The AI model for depth estimation can be trained unsupervisedly without ground truth depth maps. The AI model of some embodiments is a shared network estimating a depth map and reconstructing an AiF image from a set of images with different focus positions.
