Method and apparatus for channel measurement and reporting in CORESET basis
A UE includes a receiver configured to receive a first configuration for a first CORESET, a second configuration for a reception of a first CSI-RS, and the first CSI-RS. The first configuration includes a first TCI state. The TCI state for a CORESET indicates a set of quasi co-location properties for a PDCCH reception in the CORESET. A PDCCH includes a DCI format. The second configuration includes a first set of REs and the first TCI state. The UE also includes a processor operably connected to the receiver. The processor is configured to compute a first CQI value, based on the first CSI-RS, for a first PDCCH reception in the first CORESET and at least one CQI value based on the first CQI value. The UE further includes a transmitter operably connected to the processor, the transmitter configured to transmit a channel that includes the at least one CQI value.
