Abstract

A terminal according to one aspect of the present disclosure includes a receiving section that receives a plurality of pieces of configuration information indicating a plurality of control resource sets, and a control section that, when the plurality of pieces of configuration information do not include a control resource set pool index for one or more control resource sets of the plurality of control resource sets, determines a value of the control resource set pool index for the one or more control resource sets. According to one aspect of the present disclosure, it is possible to appropriately determine an operation for multiple panels/TRPs.

Claims (26)

1. A terminal comprising:

a receiver that receives a first configuration of a first control resource set (CORESET), a second configuration of a second CORESET, and a third configuration of a third CORESET; and

a processor that applies a value 0 to the first CORESET pool index when:

different values of CORESET pool indices are respectively configured in the second configuration and the third configuration,

the first configuration does not include a first CORESET pool index for the first CORESET, and

the second configuration includes a second CORESET pool index of a value 1 for the second CORESET.

2. The terminal according to claim 1 , wherein the processor controls reception of a first physical downlink control channel (PDCCH) in the first CORESET and reception of a second PDCCH in the second CORESET, wherein the first PDCCH schedules a first physical downlink shared channel (PDSCH), and the second PDCCH schedules a second PDSCH.

3. A radio communication method for a terminal, comprising:

receiving a first configuration of a first control resource set (CORESET), a second configuration of a second CORESET, and a third configuration of a third CORESET; and

applying a value 0 to the first CORESET pool index when:

different values of CORESET pool indices are respectively configured in the second configuration and the third configuration,

the first configuration does not include a first CORESET pool index for the first CORESET, and

the second configuration includes a second CORESET pool index of a value 1 for the second CORESET.

4. A base station comprising:

a transmitter that transmits a first configuration of a first control resource set (CORESET), a second configuration of a second CORESET, and a third configuration of a third CORESET; and

a processor that applies a value 0 to the first CORESET pool index when:

different values of CORESET pool indices are respectively configured in the second configuration and the third configuration,

the first configuration does not include a first CORESET pool index for the first CORESET, and

the second configuration includes a second CORESET pool index of a value 1 for the second CORESET.

5. A system comprising a terminal and a base station, wherein the terminal comprises:

a receiver that receives, from the base station, a first configuration of a first control resource set (CORESET), a second configuration of a second CORESET, and a third configuration of a third CORESET; and

a processor that applies a value 0 to the first CORESET pool index when:

different values of CORESET pool indices are respectively configured in the second configuration and the third configuration,

the first configuration does not include a first CORESET pool index for the first CORESET, and

the second configuration includes a second CORESET pool index of a value 1 for the second CORESET, and

the base station transmits, to the terminal, the first configuration, the second configuration, and the third configuration.
