Terminal device, integrated circuit, and radio communication method capable of reducing power consumption in radio communication system to which dynamic TDD is applied

A communication method performed by a terminal device for which one serving cell is configured, the terminal device performing a discontinuous reception functionality, the communication method comprising:

• receiving first information and second information, the first information indicating an uplink/downlink configuration, the second information indicating an uplink/downlink configuration;
• receiving information for setting first subframes for monitoring a physical downlink control channel with third information, the third information indicating an uplink/downlink configuration;
• performing a transmission process of a physical uplink shared channel which corresponds to the physical downlink control channel based on an uplink-reference uplink/downlink configuration;
• performing a transmission process of HARQ (Hybrid Automatic Repeat reQuest)-ACK (ACknowledgement) which corresponds to a physical downlink shared channel is performed based on a downlink-reference uplink/downlink configuration;
• monitoring, during an active time, the physical downlink control channel with the third information at at least a subframe which is a physical downlink control channel subframe in the first subframes;
• and
• monitoring the physical downlink control channel,
• the monitoring being performed at a second subframe during the active time
• the monitoring being performed
• based on whether or not the second subframe is a subframe instructed as
• a downlink subframe which is based on the uplink/downlink configuration indicated by the third information, and
• based on whether or not the second subframe is part of a configured measurement gap, wherein
• the physical downlink control channel subframe is a subframe indicated, by the uplink/downlink configuration indicated by the first information, as a downlink subframe or a subframe which includes a DwPTS (Downlink Pilot Time Slot),
• the active time includes a time while a timer which indicates a number of the physical downlink control channel subframe which is consecutive at a beginning of a discontinuous reception cycle is running,
• the uplink/downlink configuration indicated by the first information is the uplink-reference uplink/downlink configuration,
• the uplink/downlink configuration indicated by the second information is the downlink-reference uplink/downlink configuration, and
• the uplink/downlink configuration indicated by the third information is used for monitoring the physical downlink control channel.
