Abstract: This application relates to example Bluetooth based time synchronization methods. One example method includes performing N time synchronization subprocesses that are sequentially performed between a first electronic device and a second electronic device, where each time synchronization subprocess has one round trip time. The first electronic device obtains, based on the N round trip times of the N time synchronization subprocesses, M valid sub-time offsets corresponding to M time synchronization subprocesses, where N≥M.

Abstract: This application provides a multi-link-based communication method and an apparatus, to resolve a problem of an improper switching operation in an MLO. This application is applied to a wireless local area network system that supports a next-generation Wi-Fi protocol of IEEE 802.11ax, for example, 802.11 series protocols such as 802.11be, Wi-Fi 7, or EHT, and a next generation protocol of 802.11be, Wi-Fi 8, or Wi-Fi AI, and may be applied to a UWB-based wireless personal local area network system and a sensing system. According to the method, a related condition of a group addressed frame other than a trigger frame, a multi-station block acknowledgment frame, and a no-data PPDU announcement frame is added to a condition set, so that a non-AP STA can determine, based on information about the group addressed frame when performing a switching operation, whether to switch to a listening operation mode.

Abstract: This application discloses an Ethernet coding method and apparatus, to adapt to a scenario in which a higher transmission bit error rate is caused by a high bandwidth. The method includes: a transmit end encodes first to-be-encoded information by using a first forward error correction (FEC) codeword, to obtain first encoded data, where the first forward error correction FEC codeword is a Reed-Solomon forward error correction (RS-FEC) codeword; and the transmit end encodes the first encoded data by using a second FEC codeword, to obtain second encoded data, where a code length N and an information bit length K of the second FEC codeword satisfy the following formula: M 1 * N K ≤ M 2 , where M1 is a throughput of the first encoded data, and M2 is a throughput of the second encoded data.

Abstract: A video transmission method includes that a terminal sends first field of view information to a server through a first link based on a first period. The server receives the first field of view information from the terminal through the first link based on the first period. After determining, based on a second period, that the first field of view information is latest field of view information, the server obtains data of a first frame of image corresponding to the first field of view information, and sends the data of the first frame of image to the terminal through a second link. The terminal receives the data of the first frame of image from the server through the second link based on the second period.
