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.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a sidelink communication on a sidelink between the UE and another UE. The UE may transmit, on the sidelink, one or more feedback communications associated with the sidelink communication in a reporting period having a configurable periodicity and/or being configured to occupy an entire bandwidth of a resource pool configured for the sidelink. Numerous other aspects are provided.

Abstract: A method, a computer-readable medium, and an apparatus are provided. The apparatus communicates with a second apparatus, including transmitting or receiving a first transmission. The apparatus receives information about the second UE from a sensor at the first UE and/or from a BSM. The apparatus determines whether the first apparatus and the second apparatus are in a LOS condition based on a correlation of the information with one or more of a channel estimation, PMI feedback, or RI feedback. The apparatus may adapt a transmission parameter for a second transmission based on a predicted location of the first apparatus or the second apparatus. The transmission parameter may include at least one of a modulation, a code rate, a DMRS density, a precoder, a CSI-RS transmission periodicity or a feedback rate.

Abstract: Certain aspects of the present disclosure provide methods and apparatus for determining a Zone identifier (ID), Zone Center, and negative acknowledgement (NACK) ranges. Included are operations and means at a receiving user equipment (UE) to determine a current geographic location (GLL) of the receiving UE, and select a Zone ID based on a two-dimensional (2-D) lookup into an indexed array with the current GLL, the indexed array storing Zone data for one or more geographic Zones. The Zone data for each geographic Zone may be indexed according to geographic position, and include a Zone ID, Zone center, and one or more NACK ranges, each NACK range corresponding with a geographic Zone disposed about the geographic Zone corresponding to the Zone ID. Operations further include performing a NACK operation based on the selected Zone ID and a NACK range.
