摘要

A user terminal according to one aspect of the present disclosure includes: a reception section which monitors a first downlink control channel for cross-carrier scheduling in a first cell; and a control section which assumes that transmission configuration indication (TCI) field information indicating whether a TCI field exists in downlink control information is set to be enabled when a downlink shared channel of a second cell is scheduled by the downlink control information in the first downlink control channel and the second cell is different from the first cell. According to one aspect of the present disclosure, the information about the QCL can be appropriately determined when the user terminal configures the cross-carrier scheduling.

Embodiment 1

At least one of a state where TCI field information (tci-PresentInDCi) is set to be enabled and a state where a scheduling offset is equal to or greater than a scheduling threshold value may be applied only when a scheduling cell is different from a scheduled cell.

The scheduling cell may be replaced with a scheduling CC, a PDCCH cell, a scheduling PDCCH cell, a first cell, or the like. The scheduled cell may be replaced with a scheduled CC, a PDSCH cell, a scheduled PDSCH cell, a second cell, or the like.

For example, as illustrated in FIG. 2, when UE is configured with CORESET associated with a search space set for cross-carrier scheduling and the scheduling cell is different from the scheduled cell (a serving cell ID of the scheduling PDCCH is different from a serving cell ID of the scheduled PDSCH), the UE may assume that the TCI field information is set to be enabled for the CORESET. In this case, when one or more TCI states configured for the serving cell scheduled by a search space set include information (‘QCL-TypeD’) indicating a QCL type D parameter, the UE may assume that the scheduling offset is equal to or greater than the scheduling threshold value.
