Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a radio access network (RAN) node may transmit, to an access and mobility function (AMF) of a core network, a request associated with a location-based state of a user equipment (UE) served by the RAN node. For example, the location-based state of the UE may be associated with whether the UE is flying or whether the UE is driving. Accordingly, the RAN node may receive a message in response to the request. The RAN node may receive the message in response to the request from the AMF. Alternatively, the AMF may establish a connection between the RAN node and a location management function (LMF) of the core network such that the RAN node receives the message in response to the request from the LMF. Numerous other aspects are described.

Abstract: Methods, systems (100, 200), and devices (605, 705, 905) for wireless communications are described. For example, a method may include a receiving user equipment (UE) (115) identifying a measurement accuracy threshold associated with reporting a sensor measurement over a wireless communication link (125, 135) to the receiving UE (115). The receiving UE (115) may then transmit, to a measuring UE (115), a configuration indicating the measurement accuracy threshold for reporting to the receiving UE (115). The measuring UE (115) may make sensor measurements and identify measurement data that satisfies the measurement accuracy threshold based on the received configuration. The measuring UE (115) may then transmit, over the wireless communication link (125, 135), the subset of measurement data that satisfies the measurement accuracy threshold. The measuring UE (115) may refrain from transmitting a different subset of measurement data that does not satisfy the measurement accuracy threshold. Thus, improving communication quality by reducing the transmission of unnecessary sensor data and reducing over-the-air congestion.

Abstract: Aspects present herein relate to methods and devices for wireless communication including an apparatus, e.g., a UE and/or a base station. The apparatus may receive, from a base station, a security mode command message associated with secure sidelink communication with at least one other UE. The apparatus may also identify, based on the security mode command message, at least one of a RRC encryption key or a user plane encryption key. Additionally, the apparatus may receive, from the base station, an indication of at least one of a common base key or the RRC encryption key. The apparatus may also identify a physical layer sidelink encryption key based on at least one of the common base key or the RRC encryption key, the physical layer sidelink encryption key being associated with the secure sidelink communication with the at least one other UE.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may transmit, to a second UE via reflection by one or more passive devices, a first reference signal (RS) that is based at least in part on a shared first key that corresponds to a configuration of the one or more passive devices. The first UE may receive, from the second UE via reflection, a second RS that is based at least in part on the first key. The first UE may generate a second key based at least in part on a measurement of the second RS. The first UE may transmit a positioning reference signal that is based at least in part on the second key and that is associated with a measurement of a range between the first UE and the second UE. Numerous other aspects are described.

Abstract: A user equipment (UE) includes: a transceiver configured to send and receive communications signals wirelessly to and from a network entity; a memory; and a processor, communicatively coupled to the transceiver and the memory, configured to: send, via the transceiver to the network entity over a physical layer uplink channel, a positioning assistance request for the network entity to provide positioning assistance information indicating one or more parameters for signal exchange of one or more positioning reference signals between the UE and another device; receive the positioning assistance information from the network entity via the transceiver over a physical layer downlink channel; and perform one or more UE-device positioning functions in accordance with the positioning assistance information.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may determine to operate as a relay UE based on a set of thresholds configured for the first UE. The UE may transmit a relay discovery announcement on a communication channel of a sidelink to indicate support for relay communications. A remote UE may monitor for and receive the relay discovery announcement on the sidelink communications channel. The remote UE may select the relay UE based on a set of criteria for selecting a candidate relay UE. The remote UE and the relay UE may establish the relay communications based on the relay discovery announcement transmitted on the communications channel of the relay sidelink.

Abstract: Aspects relate to sidelink positioning using second stage sidelink control information (SCI-2). A first wireless communication device (e.g., first UE) may transmit SCI-2 including a sidelink positioning establishment message to establish a sidelink positioning session with at least a second wireless communication device (e.g., a second UE). Each of the first UE and second UE may then transmit positioning reference signals (PRSs) and generate and transmit sidelink positioning information based on the PRSs during the sidelink positioning session. The sidelink positioning information may further be transmitted via SCI-2.

Abstract: Certain aspects of the present disclosure provide techniques for configuring discontinuous reception on a sidelink connection between a remote user equipment (UE) and a relay UE. An example method generally includes determining a configuration for sidelink discontinuous reception (DRX) communications between the relay UE and a first remote UE, the configuration including a transmission configuration for communications from the relay UE to the first remote UE and a reception configuration for communications from the first remote UE to the relay UE; transmitting, to the first remote UE, a configuration message indicating the configuration for sidelink DRX communications between the relay UE and the first remote UE; and communicating with the first remote UE via a sidelink channel based on the configuration.
