User terminal and radio communication method

A radio communication method for a terminal, comprising:

• receiving configuration information of a search space set;
• and
• controlling monitoring, in the search space set, of at least one of a first downlink control information (DCI) format used for scheduling of an uplink shared channel and a second DCI format used for scheduling of a downlink shared channel, based on at least one of an ID of the search space set and a type of the search space set,
• wherein the first DCI format is other than DCI formats 0_0 and 0_1, and the second DCI format is other than DCI formats 1_0 and 1_1,
• wherein the terminal determines that for the type of the search space set, the monitoring in a common search space set (CSS) is prioritized over a UE-specific search space set (USS), and
• wherein the type of the search space set has priority over the ID of the search space set.

A base station comprising:

• a transmitting section that transmits configuration information of a search space set;
• and
• a control section that controls to monitor, in the search space set, at least one of a first downlink control information (DCI) format used for scheduling of an uplink shared channel and a second DCI format used for scheduling of a downlink shared channel, based on at least one of an ID of the search space set and a type of the search space set, in a terminal,
• wherein the first DCI format is other than DCI formats 0_0 and 0_1, and the second DCI format is other than DCI formats 1_0 and 1_1,
• wherein the control section determines that for the type of the search space set, the monitoring in a common search space set (CSS) is prioritized over a UE-specific search space set (USS), and
• wherein the type of the search space set has priority over the ID of the search space set.

A system comprising a terminal and a base station, wherein:

• the terminal comprises:
• a receiving section that receives configuration information of a search space set;
• and
• a control section of the terminal that controls monitoring, in the search space set, of at least one of a first downlink control information (DCI) format used for scheduling of an uplink shared channel and a second DCI format used for scheduling of a downlink shared channel, based on at least one of an ID of the search space set and a type of the search space set,
• wherein the control section determines that for the type of the search space set, the monitoring in a common search space set (CSS) is prioritized over a UE-specific search space set (USS), and
• wherein the type of the search space set has priority over the ID of the search space set, and
• the base station comprises:
• a transmitting section that transmits the configuration information;
• and
• a control section of the base station that controls to monitor, in the search space set, at least one of the first DCI format and the second DCI format based on at least one of the ID of the search space set and the type of the search space set, in the terminal,
• wherein the first DCI format is other than DCI formats 0_0 and 0_1, and the second DCI format is other than DCI formats 1_0 and 1_1.
