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.

說明書

The UE being configured with the CORESET associated with the search space set for cross-carrier scheduling may be replaced with the UE monitoring PDCCH for cross-carrier scheduling, the UE being configured with cross-carrier scheduling, the UE being configured with cross-carrier scheduling configuration information (CrossCarrierSchedulingConfig), the UE being configured with CIF by higher layer signaling, the UE monitoring DCI (DCI format 1_1) including the CIF, or the like.

The state where the scheduled cell is different from the scheduling cell may be replaced with a state where the serving cell ID (index) of the scheduled PDSCH is different from the serving cell ID of the scheduling PDCCH, a state where the serving cell ID of the scheduled cell is different from the serving cell ID of the scheduling cell, a state where cross-carrier scheduling configuration information for the scheduled cell indicates that the scheduling cell is other serving cells, a state where a CIF value in the DCI format 1_1 for scheduling PDSCH is one or more (not zero), or the like.

When the UE is configured with the CORESET associated with the search space set for cross-carrier scheduling and the scheduling cell is the same as the schedule cell, at least one of the state where the TCI field information is set to be enabled and the state where the scheduling offset is equal to or greater than the scheduling threshold value is not necessarily applied.
