Abstract: This application discloses a long-focus lens, a camera module, and an electronic device. The long-focus lens includes a first lens assembly, a second lens assembly, and a third lens assembly that are arranged from an object side to an image side. The first lens assembly and the third lens assembly are fixed lens assemblies, and the second lens assembly is a focusing lens assembly. In a focusing process in which the long-focus lens is switched from a long shot to a close-up, the second lens assembly moves toward the object side along an optical axis, a combined focal length of the first lens assembly and the second lens assembly decreases, and a combined focal length of the second lens assembly and the third lens assembly decreases. The foregoing long-focus lens has a strong focusing capability and high imaging quality.

Abstract: Provided are an interference finding method and apparatus, a receiving device, a transmitting device and a storage medium. The method includes: receiving measurement configuration information configured by a transmitting device; and performing, according to the measurement configuration information, a receiving measurement on a transmit beam associated with the measurement configuration information, where the receiving measurement includes a received signal strength indicator and/or a channel occupancy.

Abstract: Embodiments of this application disclose a zoom lens, a camera module, and a mobile terminal. The zoom lens includes a first lens group, a second lens group, a third lens group, and a fourth lens group that are arranged along an object side to an image side. The first lens group is a fixed lens group with positive focal power, the second lens group is a zoom lens group with negative focal power, the third lens group is a compensative lens group with positive focal power, and the fourth lens group is a fixed lens group with positive focal power. In a zooming process of the zoom lens from a short-focal end to a long-focal end, the second lens group moves towards the image side along an optical axis, and the third lens group moves towards the object side along the optical axis.

Abstract: A zoom lens, a camera module, and a mobile terminal. The zoom lens includes a first lens group, a second lens group, and a third lens group arranged along an axis extending from an object side to an image side, where the first lens group is a fixed lens group with positive focal power nearest an object side, where the second lens group is a zoom lens group with negative focal power, where the third lens group is a compensative lens group with positive focal power nearest an image side to an image side, and where the second lens group is configured to move, in a zooming process of the zoom lens from a short-focal end to a long-focal end, toward the image side along an optical axis, and the where third lens group is configured to move toward the object side along the optical axis.
