Abstract: Apparatus, methods, and computer program products for disaggregated UE are provided. An example method includes establishing a connection session. The example method may further include sharing a subscription credential with the second UE. The example method further includes transmitting a request for establishing a first protocol data unit (PDU) session via the second UE using the subscription credential. The example method further includes receiving, from the second UE, a radio resource control (RRC) configuration via the connection session to support a radio bearer with the radio access network.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may synchronize a transmission timing with the second UE via a communication link with the second UE. The UE may transmit a sidelink transmission on the communication link with an offset before or after the sidelink transmission and in accordance with the transmission timing, wherein a duration of the offset is based at least in part on a propagation delay between the first UE and the second UE, a maximum supported communication range of the first UE, or a range associated with the communication link. Numerous other aspects are provided.

Abstract: Aspects for reducing interference for transmissions in unlicensed frequency bands are disclosed. An apparatus, e.g., a user equipment (UE) with information to transmit, identifies before transmitting the information in an unlicensed frequency spectrum, a specified duration of a listen-before-talk (LBT) operation in that spectrum. Based on the specified duration, the UE reduces a transmission time duration of a slot of the UE to increase a time duration of a remainder of the slot sufficient to prevent, or decrease the likelihood of, a transmission by the UE in the slot from interfering with an LBT operation by another UE.

Abstract: To facilitate coexistence of a first radio access technology (RAT) and a second RAT, methods, apparatuses, and computer program products are provided. An example method of a first wireless device operating based on a RAT includes receiving a sidelink resource reservation from a second wireless device based on a second RAT, the sidelink resource reservation indicating a first set of resources. The example method further includes determining whether to exclude, from a candidate resource set for the first RAT within a sidelink resource pool for the first RAT, resources that overlap with the set of reserved resources for the second RAT. The example method further includes transmitting a sidelink transmission using one or more sidelink transmission resources selected from the candidate resource set in the sidelink resource pool for the first RAT.

Abstract: Techniques for wireless communications are described. A communication device, such as a user equipment (UE) may determine a resource usage level in a wireless communications system. Additionally or alternatively, the UE may determine a transmission property associated with sidelink communication at the UE. The UE may adjust, based on the determined resource usage level in the wireless communications system or the determined transmission property associated with the sidelink communication at the UE, or a combination thereof, a sensing mode of a sensing procedure or a sensing parameter of the sensing procedure, or a combination thereof. In some examples, the UE may identify a set of resources used for the sidelink communication at the UE based on the adjusted sensing mode or the adjusted sensing parameter, or a combination thereof. The UE may perform the sidelink communication based on the sensing mode or the sensing parameter, or a combination thereof.

Abstract: Certain aspects of the present disclosure provide a method for wireless communications by a transmitter UE. The method generally includes transmitting data to at least one receiver UE in an unlicensed spectrum used for sidelink communication, determining if a resource in a slot is available for the at least one receiver UE to provide acknowledgment feedback for the data transmission, and transmitting a reservation signal in the slot if the resource is determined to be available.

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: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive information identifying a shared channel occupancy for a packet transmission resource; determine a range metric for die shared channel occupancy based at least in part on location information; determine whether to share the shared channel occupancy for packet transmission using the packet transmission resource based at least in part on the range metric; and selectively transmit one or more packets in the shared channel occupancy based at least in part on a result of determining whether to share the shared channel occupancy. Numerous other aspects are provided.

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: 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.
