Abstract: Methods, systems, and devices for wireless communications are described. In some examples, a user equipment (UE) may receive, from a base station, a configuration associated with a layer to reference signal port mapping. In some cases, the UE may identify, based at least in part on the configuration, that at least one layer of a set of layers for receiving a downlink transmission from the base station is adapted based on at least one interference layer. In some cases, the adapted layer may be mapped to one or more reference signal ports. The UE may receive the downlink transmission and may decode the downlink transmission based on identifying that the at least one layer is adapted and the layer to reference signal port mapping.

Abstract: Aspects of the present disclosure relate to techniques for non-codebook based UL transmission. In some cases, a UE may signal, to a network entity, capability information of the UE for non-codebook uplink transmissions. The UE may then receive, signaling, from the network entity, indicating a plurality of sounding reference signal (SRS) configurations based at least on the signaled capability information, wherein at least one configuration indicates at least one SRS resource and determine a plurality of precoding candidates, wherein each precoding candidate is associated with a configured SRS resource. The UE may then transmit the SRSs using the associated precoding candidates.

Abstract: Disclosed are techniques for radio frequency (RF) sensing. In an aspect, a network entity (e.g., base station or road-side unit) may perform RF sensing in a first mode for sensing a horizontal angle using horizontal multiple input, multiple output (MIMO) radar with vertical beamforming, in which a two-dimensional MIMO antenna array is configured into a plurality of vertical columns, each column comprising a plurality of antenna elements configured to transmit as a phased array, each column transmitting a different orthogonal signal from the other columns. The network entity may perform RF sensing in a second mode for sensing a vertical angle using vertical MIMO radar with horizontal beamforming, in which the MIMO antenna array is configured into a plurality of horizontal rows, each row comprising a plurality of antenna elements configured to transmit as a phased array, each row transmitting a different orthogonal signal from the other rows.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive configuration information that specifies one or more parameters associated with generating, by the UE, a time domain covariance matrix specific to the UE. The UE may receive a channel state information (CSI) reference signal (CSI-RS). The UE may transmit, based at least in part on the CSI-RS and the one or more parameters, a CSI report, the CSI report including data representing the time domain covariance matrix. Numerous other aspects are described.

Abstract: Aspects of the present disclosure provide techniques for reducing channel state information (CSI) feedback overhead sent from one or more user equipments (UEs) to a network entity, such as a base station (BS) or gNodeB (gNB), while ensuring correct mapping of the CSI feedback at the network entity. In some cases, the overhead reduction may be achieved by converting the CSI feedback to size-reduced and further quantized representative coefficients (e.g., for multiple UEs). The quantized coefficients allow the network entity to recover the CSI feedback by de-quantizing and correctly mapping the quantized coefficients to recover the CSI feedback.

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: 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: 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: This disclosure provides systems, methods and apparatus for wireless communications. In one aspect, a device, such as a user equipment (UE) may receive a configuration including one or more channel state information (CSI) measurement resources associated with a set of CSI hypotheses. The set of CSI hypotheses may correspond to a set of transmission configuration indicator (TCI) states, or a CSI interference measurement (CSIIM) resource, or both. The UE may select a first CSI measurement resource of the one or more CSI measurement resources for a channel measurement based on a CSI hypothesis of the set of CSI hypotheses. The UE also may select the CSIIM resource or a second CSI measurement resource for an interference measurement based on the CSI hypothesis of the set of CSI hypotheses. The UE may, as a result, transmit a report based on the channel measurement or the interference measurement, or both.
