Abstract: Methods and apparatuses for beam management after channel setup. A method of operating a user equipment (UE) includes receiving at least one of synchronization signal/physical broadcast channel block (SSB) or channel state information reference signal (CSI-RS), measuring the at least one of the SSB or the CSI-RS, and determining downlink (DL) quasi-co-location (QCL) properties for DL communication based on the at least one of the SSB or the CSI-RS. The method further includes determining an uplink (UL) spatial domain filter for UL communication, receiving DL channels using the determined DL QCL properties until only one of only one joint TCI state or only one DL TCI state is configured, activated, or indicated to the UE, and transmitting UL channels using the determined UL spatial domain filter until only one of only one joint TCI state or only one UL TCI state is configured, activated, or indicated to the UE.

A method for operating a user equipment (UE) includes receiving a downlink control information (DCI) including at least one TCI codepoint indicating first and second TCI states; determining, based on the first or second TCI states, a third quasi co-location (QCL) assumption for receiving a physical downlink control channel (PDCCH); and receiving the PDCCH that schedules first or second transmission occasions of a first or second physical downlink shared channels (PDSCHs), respectively. The method further includes receiving information on PDSCH repetition schemes; determining, based on the first or second TCI states, a first QCL assumption for receiving the first PDSCH; and determining, based on the first or second TCI states, a second QCL assumption for receiving the second PDSCH.

Abstract: Methods and apparatuses for beam measurement and reporting in a wireless communication system. A method of operating a user equipment (UE) includes identifying an indication for reporting, in a channel state information (CSI) report, at least a first group of two resource indicators and corresponding beam metrics associated with a first entity identity (ID) and a second entity ID, respectively, and transmitting, in the CSI report, the first group of two resource indicators and the corresponding beam metrics. The first or second entity IDs correspond to at least one of: a physical cell identity (PCI) corresponding to a serving cell PCI or a PCI different from the serving cell PCI; and a PCI index pointing to a PCI corresponding to the serving cell PCI or a PCI different from the serving cell PCI in a list of PCIs that are higher layer configured to the UE.

Abstract: Methods and apparatuses for beam management, measurement and reporting for inter-cell operation in a wireless communication system. A method for operating a user equipment (UE) includes receiving a configuration for inter-cell operation, receiving a transmission configuration indication (TCI) state for a channel or a reference signal (RS), receiving information for configuring a TCI state group, and receiving an indication for associating the TCI state group with a physical cell identity (PCI). The method further includes determining, based on the information and the indication, an association between the TCI state and a PCI and determining, based on the TCI state and the association, a receive filter for reception of the channel or the RS.
