Abstract: Example transmission methods and apparatus are described. One example method includes: determining, by a network device, downlink control information (DCI), wherein the DCI includes a first request field. The first request field indicates sending reference signal from the network device to a terminal device, and the first request field triggers the terminal device to report a measurement result of the reference signal to the network device. The measurement result includes channel state information (CSI) and/or beam state information (BSI). The DCI is sent by the network device to the terminal.

Abstract: Example link recovery methods and apparatus are described. One example method includes determining a link failure of a first control resource set, where the first control resource set is a control resource set configured by a first master information block MIB. A link failure recovery request is sent, where the link failure recovery request is used to request to recover a communication link of the first control resource set. The first control resource set may be a control resource set (CORESET), a control region, or an enhanced physical downlink control channel (ePDCCH) set defined in a 5G mobile communications system.

Abstract: A slow-motion video shooting method includes detecting that a preset motion occurs on a main object in a video stream; determining a first video clip in the video stream based on the preset motion; determining a first frame rate based on the preset motion; and processing the first video clip based on the first frame rate to obtain a second video clip, where a play time of the second video clip at a target play frame rate is greater than a collection time of the first video clip, and the first frame rate is greater than the target play frame rate. When a main object for shooting moves, the first video clip, for example, a highlight clip, is obtained from the video stream, so that an electronic device can accurately capture a highlight moment of the main object.
