Abstract: Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) detects a conflict between a first sidelink reference signal transmission from a first sidelink UE and a second sidelink reference signal transmission from a second sidelink UE, wherein the first sidelink reference signal transmission at least partially overlaps with the second sidelink reference signal transmission in at least one time resource, at least one frequency resource, or both, and transmits a collision report to a third sidelink UE, the collision report including at least a collision type indicator indicating whether the first sidelink reference signal transmission and the second sidelink reference signal transmission have the same scrambling identifier.

Abstract: Disclosed are systems, apparatuses, processes, and computer-readable media for wireless communications. For example, an example of a process for performing sidelink positioning at a user equipment (UE) includes receiving, at the UE, a resource block including a plurality of sidelink symbols in a slot. The slot includes a plurality of slot portions. For instance, a first slot portion of the plurality of slot portions may include at least a first sidelink symbol with at least a first sidelink positioning reference signal (SL-PRS) resource and a second slot portion of the plurality of slot portions may include at least a second sidelink symbol with at least a second SL-PRS resource. The process may further include processing, by the UE, at least one SL-PRS resource in each of the plurality of slot portions of the slot.

Abstract: Disclosed are techniques for wireless positioning. In an aspect, a user equipment (UE) receives positioning assistance data from a location server, the positioning assistance data including at least a first expected measurement value and a first expected measurement uncertainty value defining a first search window during which the UE is expected to measure a first plurality of positioning reference signal (PRS) resources transmitted by a first transmission-reception point (TRP), determines a best symbol hypothesis that is common to a first set of PRS resources of the first plurality of PRS resources, wherein the best symbol hypothesis is a symbol within the first search window during which a signal strength of each PRS resource of the first set of PRS resources is maximized, and measures each PRS resource of a second set of PRS resources of the first plurality of PRS resources only during the best symbol hypothesis.

Abstract: Aspects presented herein may enable a UE to measure a subset of a bandwidth of PRSs, such that the UE may measure the PRSs without retuning bandwidth. In one aspect, a UE measures at least one quality metric associated with one or more channels for one or more PRSs. The UE receives, from a base station, the one or more PRSs via the one or more channels. The UE measures the one or more PRSs using at least one measuring BW of a plurality of measuring BWs, the plurality of measuring BWs being based on at least one of the measured at least one quality metric meeting a quality metric threshold, a BW for the one or more PRSs being greater than or outside of a BW for an ABWP, or a UE system BW being greater than the BW for the one or more PRSs.

Abstract: A wireless device may receive environment information associated with an area. The wireless device may simulate a set of positioning measurements based on the environment information. The wireless device may calculate a positioning environment based on the simulated set of positioning measurements. The wireless device may calculate the positioning environment further based on a set of measured positioning signals obtained by the wireless device. The wireless device may output the positioning environment to train a positioning model. The wireless device may output the positioning environment by training the positioning model at the wireless device based on the positioning environment. The wireless device may output the positioning environment by transmitting the positioning environment to a training entity to train the positioning model.

Abstract: Aspects presented herein may enable a UE to prioritize PRS and different DL channels in an RRC-inactive/idle state. In one aspect, a UE receives one or more PRSs and at least one DL channel in a measurement period and during an RRC-inactive state or an RRC-idle state, the one or more PRSs occupying a range of symbols that do not overlap with the at least one DL channel in time. The UE selects at least some portion of the one or more PRSs or at least some portion of the at least one DL channel for processing based on whether the range of symbols is within a time threshold of the at least one DL channel. The UE processes, based on the selection, the at least some portion of the one or more PRSs or the at least some portion of the at least one DL channel.

Abstract: Disclosed are techniques for wireless positioning. In an aspect, a network entity may determine that at least one sidelink positioning reference signal (SL-PRS) resource should be cancelled or rescheduled. The network entity may send, to at least one user equipment (UE), a sidelink cancellation indication (SLCI) indicating the at least one SL-PRS resource to be cancelled or rescheduled. In another aspect, a UE may determine that at least one SL-PRS resource should be cancelled or rescheduled. The UE may cancel or reschedule the at least one SL-PRS resource.

Abstract: Techniques are provided for passive positioning of user equipment (UE) with backhaul messaging. An example method for providing passive positioning information includes transmitting, with a first wireless node, assistance data associated with at least a first reference signal and a second reference signal, transmitting, with the first wireless node, the first reference signal at a first time via one or more over-the-air signals, providing instructions via a wired network connection to enable a second wireless node to transmit the second reference signal at a second time, and transmitting, with the first wireless node, turnaround time information based on the first time and the second time.

Abstract: Disclosed are techniques for communication. In an aspect, a first network entity monitors performance of a machine learning positioning model based on one or more parameters, wherein the machine learning positioning model is used for positioning a user equipment (UE), and transmits, to a second network entity, a failure indication for the machine learning positioning model based on a number of failures of the machine learning positioning model satisfying a maximum number of failures before expiration of a failure timer.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) initiates a positioning procedure in a first type of UE positioning mode, switches, during the positioning procedure, from the first type of UE positioning mode to a second type of UE positioning mode based on one or more criteria associated with a quality of a position estimate provided by the first type of UE positioning mode being satisfied, and continues the positioning procedure in the second type of UE positioning mode.
