Abstract: A central unit (CU) transmits synchronization timing information for a multicast broadcast service (MBS) single frequency network (SFN) data transmission in a synchronous manner to multiple distributed units (DUs). The CU transmits the MBS SFN data transmission to the multiple DUs for synchronous transmission to one or more user equipments (UEs). A DU receives synchronization timing information for a MBS SFN data transmission in a synchronous manner with at least one additional DU. The DU transmits the MBS SFN data transmission with a timing based on the synchronization timing information.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a serving cell, an event-based measurement report configuration that indicates a measurement threshold and a beam quantity threshold that is two or more. The UE may determine that a first set of measurements of a first plurality of reference signals satisfy the measurement threshold. Each of the first plurality of reference signals may be associated with a corresponding one of a first plurality of beams. Accordingly, the UE may transmit, to the serving cell, a report based at least in part on the first set of measurements when the first plurality of beams includes a quantity of beams that satisfies the beam quantity threshold. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a non-terrestrial network (NTN) entity, a message that is associated with an uplink grant. The UE may select, based at least in part on the message, either a cell-specific offset or an updated offset that is indicated after initial access, as a timing offset that accounts for a propagation delay between a base station of the NTN and the UE. The UE may transmit, to the NTN entity, an uplink communication using the timing offset. Numerous other aspects are described.

Abstract: Certain aspects of the present disclosure provide techniques for bandwidth part (BWP) switching by frequency shifting and/or by transmission configuration indicator (TCI) state configuration. A method that may be performed by a user equipment (UE) includes receiving a BWP configuration indicating a frequency location and bandwidth of at least a first BWP; receiving signaling indicating at least one frequency shift to determine a second BWP from a frequency location of the first BWP; and communicating on the second BWP after performing a BWP switch from the first BWP to the second BWP based on the at least one frequency shift.

Abstract: A method for wireless communication includes validating a PUR configuration in a NTN based on location-related information associated with a satellite. For example, a UE may determine, based on location-related information of a satellite in a non-terrestrial network, whether a preconfigured uplink resource (PUR) configuration is valid. The UE may also transmit, to a base station (BS) via the satellite in response to determining that the PUR configuration is valid, a communication signal in a PUR. For example, the UE may determine, based on the location-related information associated with the satellite, if the parameter satisfies the threshold, and transmit UL data in a PUR occasion based on the determined parameter satisfying the threshold.

Abstract: An apparatus may be configured to communicate at least one pilot signal with another apparatus according to a first configuration, at least one of a lower frequency density or a higher time density being indicated by the first configuration than a second configuration for a type of pilot signal that includes the at least one pilot signal. The apparatus may be further configured to communicate with the other apparatus based on the at least one pilot signal. Another apparatus may be configured to receive, from a base station, spatial relationship information or transmission configuration indicator (TCI) state information corresponding to a directional beam at the UE for communication on a channel. The apparatus may be further configured to apply the directional beam for communication with the base station on another channel in a sub-6 gigahertz (GHz) frequency band.

Abstract: In some aspects, a user equipment (UE) may receive, via a first radio access technology (RAT), system information that identifies a set of frequencies of a second RAT and one or more available multicast or broadcast (MB) services. The UE may trigger a switch from a first multicast radio bearer (MRB), of the first RAT, to a first unicast dedicated radio bearer (DRB), of the first RAT, for reception of an MB service via the first RAT. The UE may transmit an indication that indicates the MB service or a frequency via which the MB service is available via the second RAT. The UE may receive an MRB configuration associated with receiving the MB service via a target base station using the second RAT. The UE may switch from a second unicast DRB, of the second RAT, to a second MRB, of the second RAT, after handover.
