Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, an aerial user equipment (UE) may measure a first offset associated with a downlink frame based at least in part on a time when a downlink signal is received from a terrestrial base station. The aerial UE may determine a second offset corresponding to a starting time for the downlink frame at the terrestrial base station. The aerial UE may transmit an uplink message in an uplink frame using a timing advance that is based at least in part on a value of the first offset and a value of the second offset relative to a starting time associated with a global navigation satellite system frame duration. Numerous other aspects are described.

Abstract: Aspects of the present disclosure provide apparatus, methods, processing systems, and computer readable mediums for determining a beamformer to apply to groups of two or more elements of a reconfigurable intelligent surface (RIS). The beamformer is applied to the groups of elements of the RIS to facilitate communications at the operating frequency by re-radiating radio signals via the elements of the RIS. For example, by grouping RIS elements in different manners and applying a beamformer (e.g., precoding weights) to the group as if the group were a single RIS element, the RIS can be reconfigured to behave differently to suit various operating frequencies of the radio signals.

Abstract: Methods, systems, and devices for wireless communications are described. In a wireless communications system, a user equipment (UE) may use partial frequency sounding with different frequency subhop patterns so that a portion (which may be referred to as a subhop) of configured sounding reference signal (SRS) resources (e.g., a hop) are sounded. In some cases, a UE may receive a control message from a network entity identifying the frequency subhop pattern. In some cases, the network entity may configure a UE to transmit repetitions of the SRS in a same hop across consecutive symbols to increase a probability that the transmissions are successfully received and decoded by the network entity. As such, the network entity may configure a repetition factor for the frequency subhop pattern. In some cases, the frequency subhop pattern may introduce a frequency overlap between subhops.

Abstract: Methods, systems, and devices for wireless communications are described. The method may include receiving a configuration of a set of multiple report slot offset parameters, where a subset of the set of multiple report slot offset parameters is associated with a bandwidth part of a set of multiple bandwidth parts configured for the UE, receiving, during a first slot, a message triggering a channel state information report on a physical uplink shared channel of the bandwidth part, selecting a second slot for transmitting the channel state information report based on the first slot and the subset of the set of multiple report slot offset parameters associated with the bandwidth part, and transmitting, during the second slot, the channel state information report.

Abstract: A UE in one of an RRC idle mode or an RRC inactive mode may generate an emergency message including one or more of GPS coordinates, a timestamp, a UE ID, a personal ID of a user of the UE, an emergency level, or an emergency type, and transmit the emergency message to an NR-NTN. The emergency message may be transmitted in a dedicated time or frequency resource. The base station may receive the emergency message from the UE and forward the UE information to a network.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a first indication to use, for a first wireless communication, an active downlink (DL) bandwidth part (BWP). The UE may receive a second indication to use, for a second wireless communication, a restricted DL bandwidth (BW) that is based at least in part on the active DL BWP. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may detect whether a data sample falls outside of a dataset used to train a machine learning model configured by a network device. For example, a base station may transmit control signaling to the UE to indicate an out-of-distribution (OOD) detection rule configuration that the UE uses to determine whether at least one data sample falls outside of the dataset. If the at least one data sample is determined to fall outside of the dataset using the OOD detection rule configuration, the UE may transmit an indication to the base station that indicates an OOD event has occurred for the at least one sample. Additionally, the base station may parameters for determining the OOD event, OOD detection patterns to indicate when to monitor for the OOD event, or a combination thereof.

Abstract: Certain aspects of the present disclosure provide techniques for multiple codebook channel state information (CSI) report prioritization. A method of wireless communications by a user equipment (UE) includes receiving a CSI report configuration that configures one or more CSI reference signal (CSI-RS) resource sets. Each CSI-RS resource set includes one or more CSI-RS resources. The CSI report configuration also configures a plurality of codebooks for reporting CSI. The method includes receiving a priority order for the plurality of codebooks and reporting CSI based on the CSI report configuration and the priority order.
