Abstract: Methods and apparatuses for channel and interference measurement in a wireless communication system. A method for operating a user equipment (UE) includes receiving a reporting setting and receiving a resource setting associated with the reporting setting. The reporting setting is configured with a higher layer parameter reportQuantity that is set to at least cri-SINR. The resource setting is configured with a higher layer parameter resourceType that is set to aperiodic, periodic, or semi-persistent. The method further includes receiving a first set of reference signals (RSs) through a first set of RS resources; receiving a second set of RSs through a second set of RS resources; measuring at least one RS in the first or second sets of RSs; and determining, based on the reporting setting and the measured at least one RS, one or more layer-1 signal-to-noise and interference ratios (L1-SINRs).

A method for operating a user equipment (UE) includes receiving a configuration for one or more of a plurality of physical uplink control channel (PUCCH) resources that are associated with one or more of a plurality of entity identities (IDs), respectively, and receiving information for associating the one or more PUCCH resources with the one or more entity IDs, respectively. The method further includes determining, based on the configuration and the information, a PUCCH resource for a target entity ID, from the plurality of entity IDs and transmitting the PUCCH resource for the target entity ID. The target entity ID corresponds to at least one of: a physical cell ID (PCI), a CORESETPoolIndex value, a PCI index pointing to a PCI, a reference signal (RS) resource ID, a RS resource set ID, and a RS resource setting ID.
