1. A user equipment (UE), comprising:
a transceiver configured to:
receive first information for a physical cell identifier (PCI) different from a serving cell PCI; and
receive second information for source or measurement reference signals (RSs) for the PCI; and
a processor operably connected to the transceiver, the processor configured to:
determine, based on one or more transmission configuration indicator (TCI) states, the first information, and the second information, a reception spatial domain filter for reception of at least one of downlink (DL) RSs and channels from the PCI;
measure, based on the first information and the second information, the measurement RSs, wherein resources of the measurement RSs from the PCI are configured in one or more channel state information (CSI) resource settings or in one or more CSI-RS resource sets; and
determine, based on the measured measurement RSs, the first information, and the second information, a beam report, wherein the beam report for the PCI is configured in one or more CSI reporting settings,
wherein the transceiver is configured to transmit the beam report for the PCI on an uplink (UL) channel, and
wherein a beam refers to a spatial property used to receive or transmit a source RS or a channel.
