Abstract

A terminal is disclosed including a receiver that receives downlink control information from a network; and a controller that applies a slot format indicated by the downlink control information to a plurality of component carriers.

Claims (9)

1 . A terminal, comprising:

a receiver that receives downlink control information from a network; and

a controller that applies a slot format indicated by the downlink control information to a plurality of component carriers,

wherein the controller applies the slot format to all component carriers in a group comprising a subcarrier spacing (SCS) of an active downlink bandwidth part (DL BWP), an SCS of an active uplink bandwidth part (UL BWP), or a combination of the SCS of the active DL BWP and the SCS of the active UL BWP,

wherein at least one of the SCS of the active DL BWP, the SCS of the active UL BWP, or the combination of the SCS of the active DL BWP and the SCS of the active UL BWP, is a same as a reference SCS, and

wherein the reference SCS is set based on at least one of the SCS of the active DL BWP, the SCS of the active UL BWP, or the combination of the SCS of the active DL BWP and the SCS of the active UL BWP, in a designated component carrier (i) with a lowest index or (ii) from which the downlink control information is received.

2 . The terminal according to claim 1 , wherein the plurality of component carriers is contiguous within an identical frequency band.

3 . The terminal according to claim 1 , wherein an upper layer setting regarding the slot format is identical among the plurality of component carriers.

4 . The terminal according to claim 2 , wherein an upper layer setting regarding the slot format is identical among the plurality of component carriers.
