Abstract: A sounding reference signal sending method and user equipment are disclosed. The method includes the following steps: receiving a configuration parameter of a sounding reference signal SRS, and determining, based on the configuration parameter, a time-frequency resource occupied by the SRS, where the configuration parameter includes a trigger type, a period parameter, and a time-frequency resource location identifier; obtaining a power control parameter of the SRS, and calculating, based on the power control parameter and a preset calculation formula, a transmit power for sending the SRS; and sending the SRS on the time-frequency resource at the transmit power. The trigger type includes beamforming and non-beamforming. The period parameter is an identifier used to indicate that the SRS is sent periodically or aperiodically.

Abstract: The technology of this application relates to an artificial intelligence terminal-based image detection method and apparatus, and an electronic device. The method includes obtaining a to-be-detected image, determining a light source region of the to-be-detected image and a foreground region of the to-be-detected image, and determining a blurring degree of the to-be-detected image based on the light source region and the foreground region. Impact of a light source on clarity of the to-be-detected image is determined by performing light source region detection and foreground region detection on the to-be-detected image, to effectively detect whether an image shot in a backlight condition is blurred.

Abstract: Embodiments of the present invention provide a method for determining a transmission rate supported by a data stream, user equipment, and a base station. The method includes: determining, by user equipment UE, a first index corresponding to an average transmission rate supported by a channel between the UE and the base station; determining, by the UE, a second index corresponding to a difference between an instantaneous transmission rate supported by a data stream on the channel and an average transmission rate supported by the data stream on the channel; sending, by the UE, the first index to the base station; and sending, by the UE, the second index to the base station. According to the embodiments of the present invention, the instantaneous transmission rate supported by the data stream on the channel can be relatively accurately fed back to the base station, thereby improving channel resource utilization.
