Abstract: A user equipment (UE) configures a first search space (SS) set of a first slot group for multi-slot physical downlink control channel (PDCCH) monitoring (MSM) and a second SS set of a second slot group for MSM. The second SS set comprises a first type of common search space (CSS) limited to a maximum number of locations. The UE then performs MSM using the first SS set and the second SS set.

Abstract: User equipment (UE) operation in a single frequency network (SFN). The UE may receive one or more transmission configuration indication (TCI) states corresponding to one or more downlink resources, receive a demodulated reference signal (DMRS) wherein the DMRS is quasi co-located (QCLed) with one or more channel state information reference signal (CSI-RS) from multiple cells of a SFN and quasi co-location (QCL) information is included in the one or more TCI and determine a time and frequency offset corresponding to each of the multiple cells based on the CSI-RS.

Abstract: Systems and method are provided for determining access link direction beams for smart repeaters (SMRs). An SMR may be configured with a set of SMR transmission beam indicator (TBI) state (SMR-TBI State) configurations. The SMR-TBI State configurations in the set respectively comprise an SMR-TBI State identifier (ID), a cell index, and a reference signal associated with a beam for an access link between the SMR and a user equipment (UE). The SMR may receive, through a backhaul link from a base station, an indication of one or more active SMR-TBI States. For at least one of the one or more active SMR-TBI States, the SMR may forward a signal between the base station and the UE using the beam associated with the reference signal in a corresponding SMR-TBI State configuration.

Abstract: Some aspects of this disclosure relate to apparatuses and methods for supporting channel state information (CSI) report configuration for measuring time-domain channel properties (TDCP) of a channel between a user equipment (UE) and a base station. The UE can receive a CSI report configuration from the base station to configure a CSI report, where the CSI report configuration includes an indicator related to a number of tracking reference signal (TRS) resource sets for measuring TDCP of the channel. A TRS resource set can include at least two symbols in a slot for CSI reference signals (CSI-RS), and the slot is repeated to form multiple slots having a periodicity. The UE can further configure the number of TRS resource sets based on a CSI resource setting associated with the CSI report configuration, monitor the configured number of TRS resource sets to perform CSI report measurements.

Abstract: A user equipment (UE) monitors a Physical Downlink Control Channel (PDCCH) in multiple component carriers (CC). The UE determines if the UE is operating in carrier aggregation (CA) mode having a first CC in a first frequency band and a second CC in a second frequency band. When the UE is operating in CA with a first CC in the first frequency band and the second CC in the second frequency band, the UE determines a span pattern for PDCCH symbols being received on the first and second CC and selects a PDCCH monitoring type based on, at least, the span pattern. A UE also determines if a first CC and a second CC of a CA combination are collocated and selects a PDCCH monitoring type based on, at least, the determination of whether the first and second CC are collocated.

Abstract: Approaches are described for receiving downlink signals simultaneously where analog beamforming is being used to increase the link budget between the base station and user equipment (UE). Alternatives within these approaches include the UE determining the synchronization signal block (SSB) to receive when there are multiple SSBs from different cells in a slot, and determining whether there are other signals in the same symbols with the selected SSB based on the type of signal and the SSB's functionality. In the case where there are another downlink signals channel state information-reference signal (CSI-RS) or physical downlink shared channel (PDSCH) from another cell, the UE selects the corresponding quasi co-location (QCL) assumption to receive the signals. Optionally, the UE can report whether it can support one or two QCL-TypeD at a time and whether it supports SSBs in different cells multiplexed in overlapped symbols.
