According to Embodiment 1-1 described above, when the PDSCH of the same cell is scheduled by the PDCCH for cross-carrier scheduling, scheduling of the PDSCH whose scheduling offset is less than the scheduling threshold value can be performed since the scheduling offset is not limited. Thus, it is possible to perform scheduling flexibly and to improve the frequency utilization efficiency.

An operation of UE in a case where UE is configured with CORESET associated with a search space set for cross-carrier scheduling and a scheduled cell is the same as a scheduling cell or the scheduled cell is a different cell in the same band as the scheduling cell may be similar to an operation in a case where the cross-carrier scheduling is not configured.

In this case, the UE may assume that a DMRS port of PDSCH (scheduled PDSCH) of a serving cell is in QCL with RS in a TCI state for a QCL type D (or at least QCL type D) parameter used for QCL indication of PDCCH of a specific CORESET.

When the scheduled cell is a different cell in the same band as the scheduling cell, the UE does not necessarily assume that the DMRS port of the scheduled PDSCH is in QCL with RS of a TCI state for PDCCH of a specific CORESET for QCL Type A (RS of QCL Type A of the scheduled PDSCH is the same as RS of QCL Type A for PDCCH of the specific CORESET), and may assume that the DMRS port of the scheduled PDSCH is in QCL with RS of a TCI state for PDCCH of a specific CORESET for a QCL type D parameter (RS of QCL type D of the scheduled PDSCH is the same as RS of QCL type D for PDCCH of the specific CORESET).

When the scheduled cell is a different cell in the same band as the scheduling cell, the UE may use one of the following QCL Type A Assumptions 1 to 3.
