RECEPTION OF CSI-RS BASED ON QCL ASSUMPTION IN USER EQUIPMENTS WITH MIMIMUM CAPABILITY ON ACTIVE TCI STATES

摘要

A user equipment, UE has a minimum capability on active transmission configuration indicator, TCI, states, wherein the minimum capability on active TCI states supports a single active PDSCH TCI state and two active PDCCH TCI states. The UE determines if a PDSCH is scheduled or not on a same symbol as a channel state information reference signal CSI-RS, and if the PDSCH is not scheduled on the same symbol as a channel state information reference signal CSI-RS (510), the UE derives a quasi- colocation QCL assumption of the CSI-RS based on a default CSI-RS QCL assumption for UEs with the minimum capability on active TCI states (515). For instance, the UE may follow a default PDSCH QCL assumption, or a QCL assumption corresponding to a PDSCH TCI state selected by a MAC-CE, or corresponding to an active control resource set, CORESET, TCI state, or a PDSCH TCI configured by the radio resource control RRC.
