METHOD AND DEVICE FOR COMMUNICATION

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. By means of the method, the terminal device can learn the way in which the network device acquires the downlink channel information; hence, the terminal device can employ, on the basis of different ways in which the network device acquires the downlink channel information, a corresponding parameter for channel state measurement, thus reducing an error in the channel state information produced by measurement, and implementing the accurate scheduling of channel resources in a communication system.
