Abstract: Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) transmits a first signal for positioning (RS-P) (e.g., SRS, etc.) on a first link from the UE to a wireless network node (e.g., BS, UE, etc.). The UE receives, from the wireless network node, location assistance data that comprises information that indicates a line of sight (LOS) condition associated with the first link. The UE measures a second RS-P on a second link from the wireless network node to the UE that is reciprocal to the first link. The UE performs one or more positioning measurements, determines a location estimate of the UE, or both, based in part on the reception of the second RS-P on the second link and the indicated LOS condition, the indicated LOS condition associated with the second link based on link reciprocity between the first and second links.

Abstract: Disclosed are techniques for wireless sensing. In an aspect, a network node detects a collision between at least one wireless communication signal scheduled to be transmitted by the network node and two or more bundled radar reference signals scheduled to be transmitted by the network node, wherein the at least one wireless communication signal is scheduled to be transmitted during a gap between a first radar reference signal and a second radar reference signal of the two or more bundled radar reference signals; performs a collision avoidance operation based on detection of the collision, and transmits the two or more bundled radar reference signals.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a network node, an indication of a subset of tracking reference signal (TRS) resource sets from a plurality of TRS resource sets. The UE may receive, from the network node, a TRS availability indication bitmap that indicates an availability of a TRS associated with the subset of TRS resource sets. The UE may determine that the TRS is available based at least in part on the TRS availability indication bitmap. The UE may receive, from the network node, the TRS based at least in part on the TRS availability indication bitmap indicating that the TRS is available. Numerous other aspects are described.

Abstract: Position determination for a target user equipment (UE) uses a single base station and a plurality of sidelink UEs with known locations. The base station sends a reference signal to the target UE and sidelink UEs, and the target UE sends sidelink signals to each sidelink UEs. A range-sum for the range between the target UE and sidelink UE and the range between the sidelink UE and the base station can be determined for each sidelink UE, based on the time differences between the reception and transmissions of the reference signals measured by the target UE, and the time difference between reception of the reference signals measured by the sidelink UE. A differential in the range-sums can be determined and used to determine the position of the target UE.

Abstract: Techniques are provided for reducing the bandwidth required to receive reference signals with a user equipment (UE). An example method for positioning reference signal bandwidth adaptation includes determining a target accuracy, determining a positioning reference signal bandwidth based on the target accuracy, and transmitting a positioning reference signal based on the positioning reference signal bandwidth.

Abstract: Certain aspects of the present disclosure provide techniques for adaptive grouping for cooperative radar sensing. A method for wireless communications by a first network entity includes receiving, from a second network entity, first grouping information comprising an indication of a first plurality of network entities, the first grouping information associated with a first time-period; receiving, from the second network entity, second grouping information comprising an indication of a second plurality of network entities, the second grouping information associated with a second time-period; receiving a first radar signal during the first time-period; receiving a second radar signal during the second time-period; transmitting, to the second network entity, first sensing information based on the first radar signal; and transmitting, to the second network entity, second sensing information based on the second radar signal.

Abstract: Aspects presented may enable RF sensing to be adaptive to the environment to improve the sensing, performance, and/or the spectrum efficiency of cellular systems and the power efficiency of RF sensing nodes. In one aspect, an RF sensing node extracts one or more features for a set of objects of an area via at least one non-RF sensor. The RF sensing node transmits, to a network entity, the one or more features or at least one non-RF measurement derived from the one or more features. The RF sensing node receives, from the network entity, an RRS transmission configuration derived based on the one or more features or the at least one non-RF measurement transmitted to the network entity.

Abstract: In an aspect, a BS determines a CLI measurement resource configuration associated with first and second UEs, the reciprocal CLI measurement resource configuration comprising resources associated with both a CLI measurement procedure and an RTT measurement procedure between the first UE and the second UE. The BS transmits the reciprocal CLI measurement resource configuration to the first and second UEs. The first and second UEs perform both the CLI measurement procedure and the RTT measurement procedure with the second UE based on the resources associated with the reciprocal CLI measurement resource configuration.

Abstract: Disclosed are various techniques for wireless positioning. In an aspect, a base station calculates statistics of one or more time-angle metrics based on a signal received from a user equipment, and reports the statistics to a network entity, such as a location server, which uses the statistics to estimate a position of the UE. In some aspects, the network entity receives statistics from multiple base stations, which allows the network entity to more accurately determine the position of the UE. In some aspects, the base station reports the statistics to a network entity according to a statistics reporting configuration, which the network entity may provide to the base station.
