Abstract: Methods and apparatuses for dynamic beam indication and switching in a wireless communication system. A method performed by a user equipment (UE) includes receiving, in downlink control information (DCI), at least a first DCI field to indicate a first transmission configuration indication (TCI) codepoint and receiving radio resource control (RRC) signaling including a first parameter indicating whether a second DCI field indicating a second TCI codepoint is present in the DCI. The method further includes identifying, based on the first parameter, a presence or absence of the second DCI field in the DCI and identifying, based on the first and second DCI fields, a set of a first TCI state and a second TCI state. The first DCI field is a TCI field, and the second DCI field uses one or more bits of one or more existing DCI fields in the DCI.

Abstract: Methods and apparatuses for indication of dynamic beam switching via downlink control information (DCI) in a wireless communication system. A method includes receiving radio resource control (RRC) signaling including a parameter indicating a first group of transmission configuration indication (TCI) states and a second group of TCI states; receiving, in a first DCI, a first indicator and a TCI state update; and receiving, in a second DCI, a second indicator. The method further includes determining, based on the first indicator, whether the TCI state update belongs to a first TCI state from the first group of TCI states or a second TCI state from the second group of TCI states; and identifying, based on the second indicator, the first TCI state or the second TCI state to be used for receiving a physical downlink shared channel (PDSCH) or transmitting a physical uplink shared channel (PUSCH).

Abstract: Apparatuses and methods for receiving physical downlink shared channel (PDSCH) or monitoring physical downlink control channel (PDCCH) candidate in an inter-cell system. A method for operating a user equipment includes receiving an indicator for inter-cell operation; receiving first information of one or more first synchronization signal blocks (SSBs) associated with a serving cell physical cell identity (PCI); and receiving second information of one or more second SSBs associated with a PCI different from the serving cell PCI. The method further includes determining, based on the first information, one or more first resources for receiving the one or more first SSBs and determining, based on the second information, one or more second resources for receiving the one or more second SSBs. The first or second resources correspond to at least one of: (1) resource elements (REs), (2) physical resource blocks (PRBs) and (3) orthogonal frequency division multiplexing (OFDM) symbols.

Abstract: Apparatuses and methods for aperiodic channel state information (CSI) resource configuration, measurement, and reporting in a wireless communication system. A method for operating a user equipment (UE) includes receiving, in a DCI format, a channel state information (CSI) request for one or more entity identities (IDs) and receiving configuration information for an aperiodic CSI (A-CSI) trigger state. The method further includes determining, based on the CSI request, the A-CSI trigger state; determining, based on the determined A-CSI trigger state and the configuration information, one or more CSI resources associated with the one or more entity IDs; and generating one or more CSI reports based on the determined CSI resources. The entity IDs correspond to 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, or a RS resource setting ID.
