UE may be notified of M (M≥1) TCI states for PDSCH (QCL information for M PDSCHs) by higher layer signaling (M (M≥1) TCI states for PDSCH (QCL-Info for M PDSCHs) may be configured by higher layer signaling). Note that the number M of TCI states configured for UE may be limited by at least one of UE capability and a QCL type.

DCI used for scheduling of PDSCH may include a given field (which may be referred to as, for example, a TCI field, a TCI state field, or the like) indicating a TCI state for the PDSCH. The DCI may be used for scheduling PDSCH of one cell, and may be referred to as, for example, DL DCI, DL assignment, DCI format 1_0, or DCI format 1_1.

Whether or not the TCI field is included in the DCI may be controlled by information provided from a base station to the UE. The information may be TCI field information (TCI-PresentInDCI) indicating whether a TCI field is present or absent in the DCI. The TCI field information may be configured in the UE by, for example, higher layer signaling.

When more than eight types of TCI states are configured for UE, MAC CE may be used to activate (or specify) eight or less TCI states. The MAC CE may be referred to as a TCI states activation/deactivation for UE-specific PDSCH MAC CE. A value of the TCI field in DCI may indicate one of the TCI states activated by MAC CE.

If a time offset between reception of DL DCI and reception of PDSCH corresponding to the DCI is equal to or greater than a given threshold value, the UE may assume that the DM-RS ports of PDSCH of a serving cell are quasi co-located with the RS(s) in the TCI state with respect to the QCL type parameter(s) given by the TCI state indicated by the DCI.
