User terminal and radio communication method
A user terminal includes: a receiving section that receives configuration information of a search space set; and a control section that controls monitoring of downlink control information (DCI) of a first format other than formats 0_0 and 0_1 used for scheduling of an uplink shared channel and a second format other than formats 1_0 and 1_1 used for scheduling of a downlink shared channel in the search space set configured based on the configuration information. According to an aspect of the present disclosure, monitoring of downlink control information can be appropriately controlled.
1. A terminal comprising:
a receiving section that receives configuration information of a search space set; and
a control section 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 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.
2. The terminal according to claim 1 , wherein the control section controls monitoring, in the search space set, of at least one of the first DCI format and the second DCI format, based on the ID of the search space set and the type of the search space set.
3. The terminal according to claim 1 , wherein the control section determines that the monitoring is prioritized in an ascending order of the ID of the search space set.
4. 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.
5. 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.
6. 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.
7. The terminal according to claim 2 , wherein the control section determines that the monitoring is prioritized in an ascending order of the ID of the search space set.
