Terminal device, base station device, and radio communication method

A terminal device for performing radio communication with a base station device, the terminal comprising:

• a reception unit that receives cell configuration information about cell configurations from the base station device:
• an execution unit that executes, based on the cell configuration information, mobility control based on L1/L2 signaling;
• and
• a management unit that deletes a predetermined cell configuration of a plurality of the cell configurations based on information that the terminal device receives from the base station device,
• wherein the reception unit receives group information indicating a group of the cell configurations from the base station device, and
• wherein the management unit retains or deletes a plurality of pieces of the cell configuration information based on the group information and a type of the mobility control executed by the execution unit.

A base station device for performing radio communication with a terminal device, the base station device comprising:

• a transmission unit that transmits cell configuration information about cell configurations to the terminal device;
• and
• an execution unit that executes, based on the cell configuration information, mobility control based on L1/L2 signaling,
• wherein the transmission unit instructs the terminal device to delete a predetermined cell configuration of a plurality of the cell configurations by transmitting management information to the terminal device, and
• wherein the transmission unit instructs the terminal device to delete a plurality of the cell configurations by transmitting the management information to the terminal device.

A radio communication method used for a terminal device for performing radio communication with a base station device, the radio communication method comprising:

• receiving cell configuration information about cell configurations from the base station device;
• executing, based on the cell configuration information, mobility control based on L1/L2 signaling;
• and
• deleting a predetermined cell configuration of a plurality of the cell configurations based on information that the terminal device receives from the base station device,
• wherein the deleting includes deleting a plurality of the cell configurations based on information that the terminal device receives from the base station device.
