This application provides a security authentication method and apparatus applied to Wi-Fi, to help prevent a password from being shared among a plurality of devices, and implement management of a second device by a first device. In the method, an access point AP receives a first password input by the first device, where the first password is a password preset before delivery; and when checking the first password by the AP succeeds, the AP obtains a second password shared between the AP and the first device, and performs a 4-way handshake with the first device based on the second password. The second password is a shared key between the first device and the AP. Then, the AP can receive a first request from the first device, and send a third password to the first device in response to the first request.

Security authentication method and apparatus applied to Wi-Fi

Embodiments of this application provide for a wireless projection method and apparatus. The embodiments relate to the communication field and reduce an occurrence of image tearing and freezing and image quality deterioration during wireless projection to improve a user's experience. The wireless projection method is applied to a Wi-Fi communication system. In the method, an electronic device transmits a scalable video coding slice of a first video frame to a display device in a first video transmission period. The method also includes obtaining channel state information that is fed back by the display device and that is used for transmitting the first video frame. The method also includes selectively enabling a retry mechanism based on the channel state information.

Wireless projection method and apparatus

Embodiments of the present disclosure relate to the field of communication technologies and disclose a wireless projection method, apparatus, and system. The method includes: A wireless projection apparatus determines, based on a display frame rate used when the wireless projection apparatus displays an image, a duration of a first transmission period. The wireless projection apparatus negotiates with a display apparatus to determine a configuration of a time domain resource in the first transmission period, where the time domain resource in the first transmission period is configured to include a first time segment, a second time segment, and a third time segment, the first time segment is used to send first data to the display apparatus, the second time segment is used to receive second data sent by the display apparatus, and the third time segment is used for sleep.
