1. A user equipment (UE) for wireless communication, comprising:
at least one memory; and
at least one processor coupled with the at least one memory and configured to cause the UE to:
receive a Channel State Information (CSI) report configuration for Physical Downlink Control Channel (PDCCH) transmission using transmitting-receiving identities, wherein the CSI report configuration comprises an Information Element (IE) with a reportQuantity part including a field comprising one or more of a CSI Reference Signal (RS) Resource Indicator (CRI) index for aggregation level or a Synchronization Signal Block (SSB) index for aggregation level;
receive a CSI resource configuration indicating CSI resources from the transmitting-receiving identities;
receive one or more of a RS or a SSB in the CSI resources from the transmitting-receiving identities;
generate a CSI report in a format according to the CSI report configuration, wherein the CSI report comprises an indication of channel quality, the indication of channel quality comprises a value of an aggregation level, and the CSI report is generated based at least in part on one or more of the RS or the SSB; and
transmit the generated CSI report.
