Claim 4:
5. A base station device, comprising:
circuitry configured to:
transmit a downlink reference signal;
receive a first uplink reference signal from a terminal device, wherein the terminal device:
determines one of a first condition is satisfied or a second condition is satisfied, wherein
the first condition indicates that the terminal device is in a first mobility state,
the first mobility state corresponds to a state in which a number of cell reselections by the terminal device exceeds a first threshold,
the second condition indicates that the terminal device is in a second mobility state, and
the second mobility state corresponds to a state in which the number of cell reselections by the terminal device exceeds a second threshold and is less than the first threshold,

transmits the first uplink reference signal to the base station device based on the determination that the first condition, indicating that the terminal device is in the first mobility state, is satisfied and a first setting related to measurement for radio resource management,
transmits a second uplink reference signal to the base station device based on a second setting different from the first setting, and
executes downlink measurement based on the downlink reference signal and the determination that the second condition, indicating that the terminal device is in the second mobility state, is satisfied;

determine a third condition is satisfied, wherein the third condition indicates a target frequency resource is deactivated;
execute first uplink measurement based on
the deactivation of the target frequency resource, and
the first uplink reference signal received from the terminal device;

determine a fourth condition is satisfied, wherein the fourth condition indicates the target frequency resource is activated;
receive the second uplink reference signal based on the second setting; and
execute second uplink measurement based on the second uplink reference signal and the activation of the target frequency resource.
