Abstract: 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.

Abstract: This application discloses a multi-device connection establishment method and a device. The method includes: A first device sends a first message, where the first message is used to discover another device; the first device receives one or more second messages from one or more devices, where the second message is a response message for the first message; the first device determines, based on the one or more second messages, to establish a connection to a second device in the one or more devices; and the first device negotiates, with the second device, link information used to establish direct communication between the first device and the second device, and establishes a direct communication connection to the second device based on the link information. After a communication connection is established between devices based on discovery, link information is negotiated, and direct communication is established based on the link information, to form a system. In this way, there is no need to allocate specific roles to the devices. Therefore, the roles of the devices in the established distributed system are equivalent, and a service is not limited to a role problem.

Abstract: 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.

Abstract: Disclosed are a data transmission method, apparatus, and system. The data transmission method includes: sending a first multicast frame to a plurality of terminal devices; receiving multicast block acknowledgment frames respectively sent by the plurality of terminal devices, where the multicast block acknowledgment frame sent by the terminal device includes an acknowledgment field that indicates whether the terminal device receives at least one frame included in the first multicast frame; and when determining, based on the acknowledgment field included in the multicast block acknowledgment frame sent by any terminal device in the plurality of terminal devices, that the any terminal device does not receive a target frame in the first multicast frame, resending the target frame to the plurality of terminal devices. Thus, multicast frame transmission efficiency can be improved while ensuring multicast frame transmission reliability.
