Patent ID: 10917212

Abstract:
A method of default Quasi-Co-Location (QCL) assumption for Physical Downlink Shared Channel (PDSCH) reception in NR network is proposed. When PDSCH is scheduled by a DCI over PDCCH after a Scheduling Offset, the spatial RX filter for the PDSCH reception can be determined according to a QCL indication conveyed by the DCI. When the Scheduling Offset for PDSCH reception scheduled by DCI is less than a time duration, then a default QCL assumption is applied. UE assumes that the DMRS ports of PDSCH of a serving cell are QCLed with the RS(s) with respect to QCL parameter(s) used for PDCCH QCL indication of a CORESET. The CORESET is associated with a UE-monitored search space in the latest slot with the lowest CORESET-IF on an active BWP on the serving cell.
