Abstract
Provided are a method and device for communication. The method comprises: a network device transmits first information to a terminal device, the first information being used for indicating whether the network device acquires downlink channel information via an artificial intelligence algorithm model, and the artificial intelligence algorithm model being constructed by training with past uplink channel information and past downlink channel information serving as samples. A terminal device measures a channel state on the basis of the first information to acquire channel state information.
