The time offset between the reception of the DL DCI and the reception of the PDSCH corresponding to the DCI may be referred to as a scheduling offset.

Further, the above-mentioned given threshold value may be referred to as “threshold”, “threshold for offset between a DCI indicating a TCI state and PDSCH scheduled by the DCI”, “threshold-Sched-Offset”, a schedule offset threshold value, a scheduling offset threshold value, an offset threshold value, or the like.

The scheduling offset threshold value may be based on the UE capability, and may be based on, for example, the delay caused by decoding the PDCCH and beam switching. The information of the scheduling offset threshold value may be configured from the base station using higher layer signaling, or may be transmitted from the UE to the base station.

Further, if the scheduling offset is less than the scheduling offset 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 parameter(s) used for PDCCH quasi co-location indication of the lowest CORESET-ID in the latest slot in which one or more CORESETs within the active BWP of the serving cell are configured for the UE.

For example, the UE may assume that the DMRS ports of PDSCH are quasi co-located with the DL-RS based on the TCI state activated for the CORESET corresponding to the lowest CORESET-ID. The latest slot may be, for example, a slot that receives the DCI that schedules the PDSCH.

Note that the CORESET-ID may be an ID (ID for identifying CORESET) configured by the RRC information element “ControlResourceSet”.
