A terminal device that can be connected to one or more base station devices that each form one or more beams is described. The terminal device monitors, when the terminal device is not connected to any of the one or more base station devices, a connection target beam to be used when the terminal device establishes a connection with any of the one or more base station devices; and reports, at least based on a fact that the connection target beam has transitioned, information regarding the connection target beam to a base station device that forms the connection target beam. A base station device among the one or more base station devices to execute paging of the terminal device and a beam to be used in the paging are controlled based on the information regarding the connection target beam.
