Abstract: This application provides communication methods, apparatuses, and computer-readable storage media. In an example, a value of a specific element of a first access point (AP) (or a second AP) is reused in a management frame, to indicate specific elements of a plurality of APs in a multiple basic service set identifier (BSSID) set to which the first AP (or the second AP) belongs. The management frame does not need to carry a plurality of same specific elements in the multiple BSSID set. The described techniques can be applied to, for example, a wireless local area network system supporting IEEE 802.11ax next-generation Wi-Fi protocols, for example, 802.11 series protocols such as the 802.11be or the EHT.

Abstract: This application provides a coding method and a communication apparatus, which may be applied to wireless data transmission. The method includes: A sending apparatus sends indication information to a receiving apparatus, where the indication information indicates first information and second information. The first information indicates a coding scheme of to-be-encoded data, and the coding scheme includes a coding matrix for channel coding and a channel coding mode. The second information indicates a distribution feature of the to-be-encoded data. The sending apparatus performs channel coding on the to-be-encoded data based on the coding scheme, to obtain encoded data. The receiving apparatus receives the indication information sent by the sending apparatus, and the receiving apparatus performs channel decoding on received data based on the indication information, to obtain decoded data.

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.
