The UE may assume that all cells in a band use the same beam in intra-band CA (DMRS ports of PDSCHs in all the cells are in QCL for a QCL type D parameter). The UE may assume that DMRS ports of scheduled PDSCHs in all the CCs are in QCL with a scheduling PDCCH for the QCL type D parameter. Therefore, when a scheduled cell configured with cross-carrier scheduling is the same as a scheduling cell or the scheduled cell configured with cross-carrier scheduling is a different cell in the same band as the scheduling cell, the UE may apply a TCI state of the scheduling PDCCH (at least RS of QCL type D) to the scheduled PDSCH.

According to Embodiment 1-2 described above, when the scheduled cell is the same as the scheduling cell or the scheduled cell is a different cell in the same band as the scheduling cell, 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 the 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 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 ICI state for a QCL type D (or at least QCL type D) parameter used for QCL indication of PDCCH for which the PDSCH has been scheduled.
