Abstract: This application provides for an aperture, a camera module, and an electronic device. The aperture includes a base, a carrier base, a driving part, a resilient sheet, and a plurality of blades. A first optical hole for light to pass through is formed on the base. Each blade is hingedly coupled to the base, and the plurality of blades are distributed annularly around the first optical hole. A light entry hole that is formed by the plurality of blades is coaxial with the first optical hole. The carrier base is connected to the base by using the resilient sheet, and the carrier base is configured to drive each blade to rotate relative to the base. This may result in a change in the size of the light entry hole. The driving part is configured to drive the carrier base to rotate by using an axis line of the first optical hole as a rotational axis.

Abstract: A communication method and a communication apparatus are provided. The communication method includes: A first communication apparatus and a second communication apparatus determine a first identifier based on a second identifier, where a length of the first identifier is less than a length of the second identifier, and the second identifier is an identifier of the first communication apparatus. The second communication apparatus sends a first message; and correspondingly, the first communication apparatus receives the first message, where the first message includes the first identifier. The first communication apparatus wakes up. According to embodiments of this application, a quantity of bits occupied by the identifier of the first communication apparatus in the first message can be reduced, so that a capacity of the first message is increased, and the first message can be used to wake up more communication apparatuses.
