Communication method and apparatus

Abstract

A communication method and apparatus are disclosed, relating to the field of communication technologies, which enable an associated AP MLD and a second AP MLD to perform DAPS transmission based on a global sequence number, and allow the associated AP MLD and the second AP MLD to perform A-MSDU aggregation and disassembly operations respectively, thereby reducing the complexity of implementing DAPS transmission and improving communication performance. The method includes: obtaining, by an associated AP MLD, first information; sending, to a second AP MLD corresponding to the non-AP MLD for DAPS transmission, second information according to the first information; and sending, by the associated AP MLD, a PPDU formed based on a first MSDU to the non-AP MLD based on the DAPS transmission according to the second information, where the first MSDU is an MSDU including a global sequence number. The first information includes an MSDU of the non-AP MLD and a TID of the MSDU; the second information includes an MSDU, a TID, and a global sequence number allocated by the associated AP MLD to the MSDU corresponding to the TID, where the associated AP MLD is a first AP MLD corresponding to the distributed system mapping; and the first AP MLD and the second AP MLD perform DAPS transmission based on the global sequence number.
