Abstract: A transmitter sends a PPDU including a signature symbol to a receiver, where a first preset bit in the signature symbol indicates a standard version corresponding to the PPDU and/or a value of each bit in a second preset bit is 0 or 1. After the receiver receives the PPDU, if the standard version corresponding to the PPDU indicated by the first preset bit in the signature symbol in the PPDU is a standard version corresponding to a first PPDU and/or the value of each bit in the second preset bit in the signature symbol is the same as the preset value, the receiver determines that the received PPDU is the first PPDU. the transmitter and the receiver determine, by using the signature symbol in the PPDU, whether the received PPDU is the first PPDU, to identify the first PPDU, so that information in the received PPDU is correctly interpreted.

Abstract: Embodiments of this application relate to the communication field, and in particular, to a multi-link communication method and an apparatus. A STA in a STA MLD sends an information frame on a link corresponding to the station, and the information frame is used to indicate a STA in an awake state in the STA MLD. An AP MLD receives the information frame, and sends a downlink message frame on a one or more links corresponding to a part of or all of STAs in the awake state in the STA MLD, to assist the part of or all of the stations in fast accessing a channel without waiting for a NAVSyncDelay time period.

Abstract: Embodiments of this application disclose an encoding method, a decoding method, and a related apparatus, which may be applied to a wireless local area network system. An encoding apparatus determines first available bits based on to-be-encoded data bits and a first encoding rate, and determines a second codeword number and a second codeword length based on the first available bits and a correspondence between the first available bits, a first codeword number, and a first codeword length at the first encoding rate. The second codeword number is obtained based on the first codeword number, and the second codeword length is obtained based on the first codeword length. The encoding apparatus does not need to store a correspondence between available bits, a codeword number, and a codeword length at a second encoding rate, thereby reducing storage overheads of the encoding apparatus.

Abstract: The present disclosure relates to data communication methods and apparatuses. The data communication One example method includes when receiving a physical layer protocol data unit (PPDU), obtaining, by a network node, a basic service set (BSS) identifier in the PPDU. If the BSS identifier in the PPDU is different from a first BSS identifier and same as a second BSS identifier, the network node determines whether the PPDU meets a preset spatial reuse condition, where the first BSS identifier is an identifier of a first BSS to which the network node belongs, the second BSS identifier is an identifier of an extended BSS to which a target relay belongs, and the target relay and the network node belong to the first BSS. If the PPDU meets the preset spatial reuse condition, the network node contends for an access channel, and communicates with a station other than the target relay in the first BSS.
