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 a retransmitted data sending method, a retransmitted data receiving method, and a related apparatus, and relates to the field of communications technologies. In this solution, a transmit end generates a retransmitted codeword based on information bits of each codeword corresponding to an incorrect MPDU, where the retransmitted codeword includes a codeword having some of information bits included in the incorrect MPDU. For the codeword having some of information bits included in the incorrect MPDU, the transmit end punctures a correctly received information bit in the codeword, and then sends the information bit. In this way, a receive end may directly perform combined decoding or joint decoding on an LLR of a codeword of a retransmitted MPDU and an LLR of a codeword of an MPDU that is incorrectly received last time. This improves transmission efficiency and transmission reliability.
