Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may select, while operating using a first beam corresponding to a cell, a second beam corresponding to the cell based at least in part on a set of beam information associated with the second beam, wherein a first narrowband is associated with the first beam and a second narrowband is associated with the second beam. The UE may communicate with a wireless communication device that provides the cell using the second beam. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communication are described. In some examples a user equipment (UE) may transmit a message indicative of a capability of the UE to perform one or more propagation delay compensation (PDC) operations for limited band communications. In such examples, the limited band communications may be associated with communications via a carrier having a carrier bandwidth below a threshold bandwidth and the limited band communications may be associated with a link budget for a clock synchronization service. Such PDC operations may include a timing advance (TA) based PDC operation, a round trip time (RTT) based PDC operation, or both. The UE may receive a unicast control message that indicates a PDC operation of the one or more PDC operations for the limited band communications by the UE. In accordance with the unicast control message, the UE may perform the PDC operation for the limited band communications.

Abstract: Apparatuses and methods for altitude-dependent measurement and reporting configurations are described. An apparatus is configured to receive, from a network node, a measurement object configuration, where the measurement object configuration indicates at least one altitude parameter associated with a set of SSBs. The apparatus is also configured to measure a SSB value for each SSB in the set of SSBs based on the measurement object configuration and an altitude of the UE. An additional apparatus is configured to configure, for a UE, a measurement object configuration, where the measurement object configuration indicates at least one altitude parameter associated with a set of SSBs. The additional apparatus is also configured to provide the set of SSBs indicated in the measurement object configuration.

Abstract: Certain aspects of the present disclosure provide techniques for beam selection for random access. A method that may be performed by a user equipment (UE) includes receiving, from a network entity, via a first beam, system information associated with at least a first plurality of beams that are within a coverage area of the first beam. The method also includes selecting a second beam among at least the first plurality of beams based at least in part on the system information and performing a random access procedure via the selected second beam.

Abstract: Non-terrestrial networks (NTNs) may establish uplink (UL) and downlink (DL) radio frame timing structures to efficiently account for propagation delay and propagation delay variation associated with communications in the NTN. NTNs may manage (synchronize) radio frame timing structures of base stations (e.g., satellites) and user equipment (UEs) in the NTN. Further, UEs may determine timing advance (TA) values to be applied to UL transmissions based on their respective scheduling offset (e.g., offset in UL and DL radio frame timing structures), as well as based on propagation delay or round trip time (RTT). As such, served UEs may determine UL timing such that UL transmissions from the UEs to a satellite arrives at the satellite in a time synchronized manner. In other cases, a satellite may determine UL timing, based on reception timing, such that various UEs in the NTN may implement uniform UL and DL radio frame timing structures.

Abstract: A user equipment (UE) receives one or more timing advance commands from a non-terrestrial network (NTN). The UE resets, after a GNSS fix, a cumulative timing advance value based on the one or more timing advance commands from the NTN and transmits an uplink transmission with a timing advance based on a self-estimated delay and the cumulative timing advance value. The UE may adjust a self-estimated delay based on at least one GNSS fix. The UE may transmit an uplink transmission with a timing advance based on the adjusted self-estimated delay and a cumulative timing advance value based on the one or more timing advance commands from the NTN.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a synchronization signal/physical broadcast channel (SS/PBCH) block index, associated with an SS/PBCH block, based at least in part on a set of bits included in a payload of a PBCH of the SS/PBCH block, a demodulation reference signal (DMRS) sequence included in the PBCH, a scrambling sequence associated with the PBCH, or an interleaving associated with the PBCH. Numerous other aspects are described.

Abstract: A user equipment (UE) selects or reselects a target cell of a non-terrestrial network or resumes connectivity with the target cell after a satellite handover for a permanently fixed low Earth orbit (LEO) cell. The target cell is a serving or non-serving cell. The UE determines a cell type of the target cell. The cell type may be a LEO cell type, a geostationary Earth orbit (GEO) cell type, a moving cell type, a fixed cell type, a temporarily fixed LEO cell type, or a permanently fixed LEO cell type. The UE completes selection or reselection of the target cell or completes the connectivity with the target cell, based on the cell type.

Abstract: RACH occasion repetition and PRACH format selection in an NTN are disclosed. The base station may determine, based on at least one beam, a first PRACH configuration for at least one first UE and a second PRACH configuration for at least one second UE. The base station may transmit, to at least one of the at least one first UE or the at least one second UE, an indication of the first PRACH configuration and the second PRACH configuration. The UE, based on whether it is a first UE or a second UE, may select, based on the received indication, the first PRACH configuration or the second PRACH configuration for at least one beam. The UE may initiate, via the at least one beam, a RACH procedure for the selected first PRACH configuration or the selected second PRACH configuration.
