摘要： Embodiments of this application disclose a communication method and a communication apparatus. The method includes: A transmit end performs first encoding processing on first data by using an encoder neural network, to obtain a first sent feature, where the first sent feature is related to a channel distribution dimension of an environment in which the transmit end is located. The transmit end performs second encoding processing on the first sent feature by using a matching layer, to obtain a first feature, where the encoder neural network and the matching layer are obtained through independent training. The transmit end sends the first feature to a receive end, where the first feature is used by the receive end to obtain the first data. Because the encoder neural network and the matching layer are obtained through independent training, when a channel changes, adaptation to a new channel can be implemented by updating only the matching layer of the transmit end, so that a current channel may be adjusted within a shorter time, and overheads required for network training of the receive end are reduced. In addition, because the receive end does not need to participate in training, a requirement for a processing capability of the receive end can be reduced, so that use duration of the receive end can be prolonged.
