Abstract: Embodiments provide a power adjustment method and an access network device, and the embodiments relate to the field of communication technologies. A target power increase value is adaptively determined based on a target key characteristic of a target cell, so that a cell coverage loss and a cell capacity loss caused by channel shutdown are compensated for, and a good energy-saving effect is obtained. The access network device blocks transmit channels that are of some of a plurality of antennas and that correspond to the target cell. Then, the access network device obtains the target key characteristic of the target cell, and determines the target power increase value based on the target key characteristic. The access network device increases, based on the target power increase value, transmit power of the access network device corresponding to the target cell or a target user.

Abstract: An event information processing method and a first electronic device for implementing the method are provided, and relate to the field of communication technologies. The method includes: A first electronic device receives a first message sent by a second electronic device. The first message carries a trust level of the second electronic device. The first electronic device determines whether the trust level of the second electronic device meets a preset condition. When the trust level of the second electronic device meets the preset condition, the first electronic device sends a first event to the second electronic device. According to the technical solution, selective event synchronization can be implemented.

Abstract: A display method and apparatus are disclosed. The method includes: joining, by a first device, a device group, where the device group includes N devices, any two devices in the N devices can communicate with each other, and N≥2; receiving, by the first device, a first selection operation entered by a user, where the first selection operation is used to trigger the first device to communicate with a second device in the device group; sending, by the first device, a first screen projection request to the second device in response to the first selection operation, where the first screen projection request is used to request to project a display interface of the second device onto a display screen of the first device; receiving display data in the display interface of the second device that is sent by the second device; and displaying based on the display data.
