Abstract
This application provides a communication method and apparatus that allow retransmitted MPDUs with different retransmission versions (RVs) to be transmitted in a same transmission process. The communication method and apparatus may be applied to a data retransmission process between any two nodes in a Wi-Fi system. In the method, when a PPDU sent by a first node includes one or more retransmitted MPDUs, the first node may include RV indication information in the PPDU to indicate an RV of each retransmitted MPDU, so that a second node can properly receive each retransmitted MPDU based on the RV indication information.
