A communication method includes: a first device determines a first channel access manner based on network status information, wherein the first channel access manner is a carrier sense multiple access with collision avoidance (CSMA/CA) channel access manner or an intelligent channel access manner, and the intelligent channel access manner is a manner of accessing a channel based on a channel access decision obtained by a neural network; and sends data on a channel in the first channel access manner. The first device selects the first channel access manner based on the network status information, and sends the data in the first channel access manner.
