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: A UE may include IoT NTN device, and the UE may acquire the GNSS location to perform the time/frequency pre-compensation. A NAS layer of the UE may initiate a connection request procedure based on the GNSS fix procedure at one or more lower layer of the UE. A network may transmit a paging request to the UE, and manage a paging response timer based on the GNSS fix procedure at the UE.

Abstract: A method, base station (BS), user equipment (UE), apparatus, and computer program product for wireless communication are provided. A BS and a UE may communicate using a narrowband Internet of Things (NB-IoT) communication system. However, a frequency, time, and/or power associated with transmission of a SIB1-NB on a non-anchor carrier may not be configured for NB-IoT. In some aspects, the BS may determine parameters, such as a time domain location parameter, a frequency domain location parameter, a quantity of repetitions, a power boosting parameter, and/or the like for a transmission in NB-IoT. In some aspects, a UE may determine to transmit a connection request message on a different carrier than a random access channel message.

Abstract: Aspects presented herein may enable a base station to map one or more DMRSs to one or more REs of a slot based on the locations of one or more CRSs in the slot and/or based on whether at least one DMRS overlaps with at least one CRS. In one aspect, the base station maps PDCCH DMRS of a first RAT to a CORESET based on whether CRS of a second RAT overlaps at least partially with the CORESET. The base station transmits the PDCCH DMRS mapped to the CORESET.

Abstract: Support for hybrid automatic repeat request acknowledgment feedback for multiple multicast services in 5G new radio (NR) is provided. Resource allocation techniques are provided to allocate uplink control channel resource for acknowledgment of downlink multicast data transmissions associated with one or more multicast services. An apparatus, such a user equipment (UE), receives multicast data associated with one or more multicast services from a base station. The apparatus determines an uplink resource, such as a physical uplink control channel (PUCCH) resource, for transmitting multicast acknowledgement feedback, such as positive acknowledgement (ACK)/negative acknowledgement (NACK) feedback, in response to the received multicast data. The apparatus transmits the acknowledgement feedback for the one or more multicast services to the base station in the determined uplink resource.

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: Aspects relate to one or more configurations for wireless communication via a radio frequency (RF) band. A user equipment (UE) and a base station (BS) may support communication on a first RF band. A first minimum bandwidth size may be defined for first RF band. The first minimum bandwidth size may be smaller than a second minimum bandwidth size defined for a second RF band available to the UE. The UE and the BS may each communicate via the first RF band according to a first configuration that is based on the first minimum bandwidth size.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may start a timer after a repetition of a communication, where calculation of a length of the timer includes an offset that corresponds to a propagation delay between the UE and a base station via a non-terrestrial network (NTN) entity. The UE may start a discontinuous reception (DRX) retransmission timer after expiration of the timer. Numerous other aspects are described.

Abstract: A user equipment may be configured to perform cell reselection during a gateway and/or satellite switch. In some aspects, the user equipment may select a current cell of a satellite device in a radio access network (RAN) and receive, from the satellite device, cell reselection information for identifying a destination cell for selection in response to a link modification. Further, the user equipment may select, via a cell reselection process, the destination cell based on the cell reselection information.
