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

An apparatus for accessing a wireless fidelity (Wi-Fi) network, including a Wi-Fi processor and N Wi-Fi access circuits. N is a natural number greater than or equal to 2. The Wi-Fi processor is shared by the N Wi-Fi access circuits and implements an operation function related to Wi-Fi. The N Wi-Fi access circuits receives and transmits data at a same time through N Wi-Fi networks that operate on different radio frequency bands. Each Wi-Fi access circuit of the Wi-Fi access circuits comprises a Media Access Control (MAC) hardware and a physical layer (PHY) hardware.

Method and apparatus for accessing WiFi network to support a terminal connected to two or more WiFi networks at the same time

A method and an apparatus for accessing a WI-FI network supporting a terminal in being coupled to two or more WI-FI networks at the same time, and therefore, WI-FI network is applied in a safer and more fluent manner. The method is applied to a terminal, the terminal includes N WI-FI access circuits and at least one processor, the at least one processor is configured to run a software program to form M containers, one container may be equivalent to one operating system, switch operation may be performed between different containers, each container corresponds to one WI-FI network access service, the M containers are capable of operating at the same time, tasks and data of different WI-FI network access services during operation of different containers are mutually isolated, and M and N are natural numbers greater than or equal to two.

Method and apparatus for accessing WI-FI Network

A method of frame synchronization includes: inserting synchronous pilots including odd synchronous pilots and even synchronous pilots in a frame; transmitting first signals on the odd synchronous pilots, and transmitting second signals of inverse values of the first signals transmitted on the odd synchronous pilots on the even synchronous pilots; synchronizing the frame according to the odd synchronous pilots and the even synchronous pilots. With the method provided by embodiments of the present invention, complexity of the frame synchronization may be decreased and delay of the frame synchronization may be reduced.
