Communication method and device

The invention relates to the technical field of communication, and discloses a communication method and device. The method comprises: a terminal device sending first indication information to a network device, the first indication information indicating at least one switching time delay, the at least one switching time delay corresponding to at least one switching type of a radio frequency link of the terminal device switched among a plurality of frequency bands; and the terminal device communicates with the network device based on the at least one switching time delay. By adopting the method, the terminal equipment can report at least one switching time delay to the network equipment, so that the terminal equipment and the network equipment can communicate based on the at least one switching time delay; furthermore, the terminal equipment can report the switching time delays corresponding to different switching types to the network equipment according to the switching types, so that the signaling overhead ca
