Abstract: Embodiments of this application disclose a signal transmission method and a related device thereof. The method in this application includes: obtaining N parameters of a target cell, where the parameters indicate a real-time status of the target cell, and N is an integer greater than or equal to 1; and shutting down at least one first orthogonal frequency division multiplexing (OFDM) symbol in a first subframe of the target cell after determining that at least one of the N parameters is less than or equal to a corresponding threshold and determining that each terminal device in connected mode in the target cell is in a discontinuous reception (DRX) sleep period or that no terminal in connected mode exists in the target cell, where the first OFDM symbol carries a cell specific reference signal CRS corresponding to a first port and/or a second port.

Abstract: An electronic apparatus includes a controller, an image signal processor, an artificial intelligence AI processor, and a central processing unit. The processor is configured to: obtain a first signal that indicates a light intensity variation from an ambient light sensor, and trigger, based on the first signal, a camera apparatus to collect a first image. The image signal processor is configured to: receive the first image from the camera apparatus, process the first image to generate a second image, and provide the second image to the AI processor. The AI processor detects the second image to obtain an image detection result. The central processing unit is configured to perform a response operation based on the image detection result.
