Terminal device, base station device, radio communication method, and integrated circuit

A terminal device comprising:

• reception circuitry configured to receive information indicating a number of transmission repetitions for physical downlink control channel, and
• physical layer control circuitry configured to perform radio link monitoring based on a threshold being defined as a level of a downlink radio link, wherein
• a value of the threshold corresponds to a specific block error rate of a physical downlink control channel transmission with the number of transmission repetitions, and
• a maximum value applicable to a timer used for the radio link monitoring is larger than a maximum value applicable to a timer used for radio link monitoring in a terminal device which is not configured with a number of transmission repetitions for physical downlink control channel.
