1. A terminal device that can be connected to one or more base station devices that each form one or more beams, the terminal device comprising:
at least one processor; and
at least one memory storing instructions that, when executed by the at least one processor, cause the at least one processor to function as:
a monitoring unit for monitoring, in a first state, between a connected state and an idle state, in which a resource radio control (RRC) is not established but the terminal device can send a certain signal to any one of the one or more base station devices, a connection target beam to be used when the terminal device establishes a connection with the any one of the one or more base station devices;
a reporting unit for reporting information regarding the connection target beam to the any one of the one or more base station devices that forms the connection target beam in response to determining that a condition, received from at least one of the one or more base station devices, for reporting that the connection target beam has transitioned from one of the one or more beams to another beam of the one or more beams, is satisfied when the terminal device is satisfied in the first state, wherein the condition comprises at least one of:
a number of transitions of the connection target beam in the first state reaches a first predetermined value being more than one; or
a number of beams to which the connection target beam has transitioned in the first state reaches a second predetermined value being more than one; and
a receiving unit for receiving, from the at least one of the one or more base station devices, the condition under which the reporting unit reports the information regarding the connection target beam, and
a detection unit for performing a measurement to detect a signal used to discover one of one or more cells to be connected when the terminal device establishes the connection with the any one of the one or more base station devices, wherein each of the one or more base station devices forms the one or more cells.
