Abstract

Even when inter-cell mobility is performed using a plurality of transmission/reception points, communication is appropriately performed. A terminal according to one aspect of the present disclosure includes a receiving section that receives information related to activation of a transmission configuration indication (TCI) state, and a control section that controls monitoring of a downlink control channel related to paging, based on whether or not the TCI state corresponding to a serving cell is included in the TCI state to be activated.

Claims (16)

1 . A terminal comprising:

a receiver that receives information regarding activation of a transmission configuration indication (TCI) state; and

a processor that controls monitoring of a downlink control channel related to paging, based on whether or not a TCI state corresponding to a serving cell is included in an activated TCI state.

2 . The terminal according to claim 1 , wherein when the TCI state corresponding to the serving cell is not included in the activated TCI state, the processor controls not to monitor a downlink control channel related to paging transmitted from an other cell different from the serving cell.

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

receiving information regarding activation of a transmission configuration indication (TCI) state; and

controlling monitoring of a downlink control channel related to paging, based on whether or not a TCI state corresponding to a serving cell is included in an activated TCI state.

4 . A base station comprising:

a transmitter that transmits information regarding activation of a transmission configuration indication (TCI) state; and

a processor that controls transmission of a downlink control channel related to paging, monitoring of the downlink control channel related to paging being controlled based on whether or not a TCI state corresponding to a serving cell is included in an activated TCI state.

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

the terminal comprises:

a receiver that receives information regarding activation of a transmission configuration indication (TCI) state; and

a processor that controls monitoring of a downlink control channel related to paging, based on whether or not a TCI state corresponding to a serving cell is included in an activated TCI state, and

the base station comprises:

a transmitter that transmits the information.
