1. A method performed by a user equipment (UE) for handling physical downlink shared channel (PDSCH) reception, the method comprising:
receiving, from a base station (BS), a first PDSCH configuration in a common frequency resource (CFR) configuration for a multicast PDSCH, the first PDSCH configuration including a first aperiodic resource set configuration;
receiving, from the BS, a second PDSCH configuration in a bandwidth part (BWP) configuration for a unicast PDSCH, the second PDSCH configuration including a resource configuration and a second aperiodic resource set configuration, wherein:
the resource configuration is used for configuring one or more zero-power (ZP) channel state information-reference signal (CSI-RS) resources,
the resource configuration is absent in the first PDSCH configuration,
the first aperiodic resource set configuration is used for configuring a first list of ZP CSI-RS resource sets associated with the resource configuration,
each of the first list of ZP CSI-RS resource sets includes at least one of the one or more ZP CSI-RS resources, and
the second aperiodic resource set configuration is used for configuring a second list of ZP CSI-RS resource sets associated with the resource configuration;
receiving, from the BS, first downlink control information (DCI) scheduling the multicast PDSCH, the first DCI including a first field for triggering a first aperiodic ZP CSI-RS; and
determining, based on the first field, a first ZP CSI-RS resource set, which is not available for reception of the multicast PDSCH, from the first list of ZP CSI-RS resource sets.
