1. A user equipment (UE) comprising:
a transceiver; and
a processor operably coupled to the transceiver, the processor configured to;
identify whether a parameter of a higher layer configuration for a control resource set (CORESET), received from a base station, is set as enabled or not;
when the higher layer parameter is set as enabled, for downlink (DL) control information (DCI) of a first DCI format:
identify an indication field is present in the DCI of the first DCI format, conveying a DL assignment, transmitted by a physical DL control channel (PDCCH) on the CORESET, and
identify a first quasi co-location (QCL) parameter for a physical DL shared channel (PDSCH) antenna port based on the indication field; and
when the higher layer parameter is not set as enabled, for the DCI of the first DCI format thereby indicating that the indication field is absent or DCI of a second DCI format different from the first DCI format is received:
use a second QCL parameter for PDSCH which is identical to a QCL parameter used for receiving the PDCCH, and
control the transceiver to receive, from the base station, data over the PDSCH using the first QCL parameter or the second QCL parameter.
