The state where the scheduled cell is the same as the scheduling cell may be replaced with a state where the serving cell ID of the scheduled PDSCH is the same as the serving cell ID of the scheduling PDCCH, a state where the serving cell ID of the scheduled cell is the same as 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 the own serving cell, a state where a CIF value in the DCI format 1_1 for scheduling PDSCH is zero, a state where PDSCH is scheduled according to DCI format 1_0 (not including CIF), or the like.

The UE may operate according to at least one of the following Embodiments 1-1, 1-2, and 1-3.

When UE is configured with CORESET associated with a search space set for cross-carrier scheduling and a scheduling cell is the same as a scheduled cell, the UE may operate similarly to a case where the cross-carrier scheduling is not configured.

For example, as illustrated in FIG. 3, when the scheduling offset is smaller than the scheduling offset threshold value and a serving cell index of a scheduling PDCCH is the same as a serving cell index of a scheduled PDCCH in both of a case where TCI field information is set to be enabled and a case where the TCI field information is not set in RRC, the UE may assume that a DMRS port of PDSCH of the serving cell has the lowest CORESET-ID in the latest slot in which one or more CORESETs in an active BWP of the serving cell are monitored by the UE and is in QCL with RS in a TCI state related to a QCL parameter used for QCL indication of PDCCH of CORESET (specific CORESET) associated with a search space to be monitored.
