A method of channel state information (CSI) report can include receiving a CSI report configuration at a user equipment (UE) from a base station. The CSI report configuration indicates CSI reference signal (CSI-RS) resources configured for transmitting CSI-RSs from multiple transmission and reception points (TRPs). An CSI-RS measurement process can be performed at the UE based on the CSI-RSs transmitted from the multiple TRPs using the CSI-RS resources indicated by the CSI report configuration. A CSI report can be transmitted from the UE to the base station based on the CSI report configuration. The CSI report includes information of one or more phase differences or one or more amplitude differences among the CSI-RSs transmitted from the multiple TRPs.

Downlink multi-antenna transmission in wireless communication system

A method of configuring a set of active cells among neighboring cells to reduce latency and interruption for inter-cell mobility is proposed. The set of active cells is an active set of cells among which UE can do fast cell switching. The set of active cells is configured by the network based on UE measurement report or network deployment information. UE maintains the configuration and can perform pre-synchronization to the configured active cells in downlink (DL) only or in both DL and uplink (UL). UE maintains the DL/UL synchronization with the active cells, and applies configuration once UE is indicated to switch to an active cell as the target cell. Because UE maintains the configuration and DL/UL timing of the target cell before receiving the cell-switch command, the mobility latency and interruption time for inter-cell mobility is reduced.

Mobility between configured cells

A device for recording videos includes an image signal processor to process frames captured in response to a request for recording a video at a first frame rate, and a video encoder to encode captured frames. The device also includes processing circuitry operative to allocate image buffers from memory in response to the request, and execute a camera software to direct the image signal processor to fill each image buffer with a batch of the captured frames. For each filled image buffer, a reference of the image buffer is passed from the camera software to a video software at a second rate, which is a fraction of the first frame rate. The processing circuitry then executes the video software to provide one frame at a time to the video encoder for encoding at the first frame rate.

High framerate video recording

An image processing method is provided. The image processing method includes the following steps: detecting an input sequence of image frames captured using an image capturing device to generate a detection result; referring to the detection result to selectively perform frame interpolation on the input sequence of image frames to generate a to-be-encoded sequence of image frames; and encoding the to-be-encoded sequence of image frames to generate an encoded video signal.

Image processing method and apparatus and system for dynamically adjusting frame rate

A method for performing fluent playback control is provided, where the method is applied to an electronic device. The method includes the steps of: determining whether an out of synchronization status regarding audio playback and video playback occurs; and when it is detected that the out of synchronization status occurs, controlling jump timing of video playback according to at least one of scene change detection and standstill detection. For example, the scene change detection can be performed to determine whether a scene change exists, and when it is detected that the scene change exists, a jump operation of video playback is triggered. In another example, the standstill detection can be performed to determine whether a standstill phenomenon exists, in order to determine whether to delay triggering a jump operation of video playback. In another example, a temporary audio pause operation can be selectively performed. An associated apparatus is also provided.
