Abstract

A terminal device includes a transmission processing part configured to notify the network of a type of the terminal device, and a reception processing part configured to derive the required number of repetitive transmissions and/or repetitive receptions (the first number of repetitions) on the basis of downlink reference signal received power. The terminal device measures the downlink reference signal received power on the basis of the first measurement period longer than 200 ms, upon deriving the first number of repetitions. The type of the terminal device notified to the network is different from a type of a terminal device employing a measurement period of 200 ms.

Claims

1-8. -8. (canceled)

9. 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 period for first estimation of downlink quality, the first estimation being for the radio ink monitoring, is longer than a period for second estimation of downlink quality, the second estimation being for radio ink monitoring of a terminal device which is not configured with a number of transmission repetitions for physical downlink control channel.

10. A communication method for a terminal device, the communication method comprising:

receiving information indicating a number of transmission repetitions for physical downlink control channel, and

performing 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 period for first estimation of downlink quality, the first estimation being for the radio ink monitoring, is longer than a period for second estimation of downlink quality, the second estimation being for radio ink monitoring of a terminal device which is not configured with a number of transmission repetitions for physical downlink control channel.
