    Abstract: This disclosure provides systems, methods, and devices for wireless communication that support fifth generation (5G) new radio (NR) radio frequency (RF) sensing with polarization configuration. In a first aspect, a method of wireless communication includes receiving at a network node participating in 5G NR RF sensing a first polarization indicator and a second polarization indicator from a network entity. The first polarization indicator is associated with transmission of a first reference sensing signal and the second polarization indicator is associated with reception of a second reference sensing signal. The network node performs sensing measurements using the first polarization indicator and the second polarization indicator and transmits a sensing measurement report including the sensing measurements associated with the second reference sensing signal to the network entity. Other aspects and features are also claimed and described.

    Abstract: In some implementations, an example method of wireless communication at a base station for wireless positioning a user equipment (UE) may comprise: transmitting, to a different device, assistance indicating a location of antenna reference points (ARPs) of the base station for a first set of TRPs configured for receiving uplink (UL) sounding reference signals (SRSs) different from a location of antenna reference points (ARPs) of the base station for a second set of TRPs configured for transmitting downlink (DL) position reference signals (PRSs). The method also comprises performing a measurement of a UL reference signal received by the first set of TRPs. And the method further comprises transmitting the measurement to the different device.

    Abstract: Methods, systems, and devices for wireless communication are described. Aspects of the disclosure describe narrow beam-based channel access that enables a device to communicate in a shared radio frequency spectrum band without performing channel access procedures. Specifically, aspects of the disclosure describe techniques for defining one or more directional beams as a narrow beam, where the relative narrowness of the beam may be determined in the context of interference (e.g., as opposed to being defined from a geometric perspective). For example, a particular beam may be determined to be a narrow beam, and therefore associated with communications in shared radio frequency spectrum bands without channel access procedures, based on one or more metrics and a number of spatial streams associated with the beam. A device may use such narrow beams for communications without channel access procedures in shared radio frequency spectrum bands.

    Abstract: Aspects presented herein may enable an ML module to associate RF fingerprints with beam directions and/or beam features to improve the uniqueness of RF fingerprints. In one aspect, network entity may receive, from one or more wireless devices, a plurality of first RF fingerprints, each of the plurality of first RF fingerprints being associated with at least one directional feature and a location. The network entity may receive a request to determine a position of a UE based on at least one second RF fingerprint associated with the UE or captured by the UE. The network entity may estimate the position of the UE based at least in part on matching the at least one second RF fingerprint to at least one of the plurality of first RF fingerprints.

    Abstract: This disclosure provides systems, methods, and devices for wireless communication that support machine learning (ML) positioning model monitoring and life cycle management. In some aspects, a user equipment (UE) may receive, from a network entity, a configuration message associated with a first set of reference signals and a second set of reference signals. The UE may perform first measurements based on the first set of reference signals received from a first set of transmit/receive points (TRPs) to generate first measurement data. The UE may perform second measurements based on the second set of reference signals received from a second set of TRPs to generate second measurement data. The UE may transmit, to the network entity, a reporting message based on the second measurements or based on the first measurement data and the second measurement data. Other aspects and features are also claimed and described.
