Abstract: Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) monitors one or more physical downlink control channel (PDCCH) candidates in a search space while in a radio resource control (RRC) inactive state, receives, while in the RRC inactive state, a positioning paging message from a network entity on at least one PDCCH candidate of the one or more PDCCH candidates, the positioning paging message configured to trigger an update to one or more parameters associated with an ongoing positioning session involving the UE, applies, while in the RRC inactive state, the update to the one or more parameters, and transmits, while in the RRC inactive state, an acknowledgment to the network entity in response to reception of the positioning paging message.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a base station (BS) transmits, to a user equipment (UE), a first configuration of a first radio access network notification area (RNA) associated with paging of the UE while the UE is in an radio resource control (RRC) INACTIVE state, the first RNA comprising a first set of cells. In a further aspect, the BS transmits, to the UE, a second configuration of a second RNA associated with positioning of the UE while the UE is in the RRC INACTIVE state, the second RNA comprising a subset of the first set of cells.

Abstract: Disclosed are techniques for wireless communication, and specifically for reconfigurable intelligent surface (RIS)-aided positioning. In some aspects, a base station (BS) may transmit, to a user equipment (UE), a first positioning reference signal (PRS). The BS may transmit, to RIS configured to reflect a received signal towards the UE, a second PRS. The BS may receive, from the UE, a downlink reference signal time difference (RSTD) measurement for the first PRS and the second PRS.

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: A signal processing method includes: receiving, at a UE, a PRS and a supplemental signal, the supplemental signal being a broadcast signal and spanning a first frequency range at least partially outside of a second frequency range spanned by the PRS; processing, at the UE, the PRS and the supplemental signal in combination, resulting in an effective signal bandwidth that is larger than the second frequency range, to determine position information; and at least one of: transmitting a capability message, from the UE to a network entity, indicating a processing capability of the UE to process, in combination, the PRS and the supplemental signal; or transmitting a signal-combination indication, from the UE to the network entity, indicating that the UE processed the PRS and the supplemental signal in combination to determine the position information.

Abstract: Disclosed are various techniques for wireless communication. In an aspect, a user equipment identifies a set of positioning sources, each positioning source comprising a positioning reference signal (PRS) resource, a PRS resource set, a PRS frequency layer, and/or a transmission/reception point. From the set of positioning sources, the UE identifies a consistency group comprising a collection of positioning sources grouped based on expected values of at least one metric of a reference signal from each positioning source, measured values of the at least one metric for the reference signal from each positioning source, and an error threshold. The UE identifies one or more subsets of positioning sources within the consistency group, each subset having at least one metric error value. The UE reports, to a network entity, information about the consistency group and information about at least one of the subsets of positioning sources within the consistency group.

Abstract: In an aspect, a radar controller determines a first transmission configuration for a reference radar signal on a first link from a first base station to a second base station, and a second transmission configuration for at least one target radar signal on at least one second link from the first base station to the second base station, the at least one target radar signal for sensing of at least one target, the first transmission configuration being different than the second transmission configuration. The radar controller transmits the first and second transmission configurations to the first and second base stations. The first base station transmits the reference radar signal and the at least one target radar signal in accordance with the respective transmission configurations.

Abstract: Method and apparatus to signal insertion loss for SRS antenna switching. The apparatus determines an insertion loss for each antenna of a plurality of antennas. The apparatus generates an offset matrix correction based at least on the insertion loss for each antenna of the plurality of antennas. The apparatus transmits the offset matrix correction to a base station. The apparatus may transmit an SRS, at a maximum power, from each antenna of the plurality of antennas to each receive antenna of the base station. The apparatus may collect insertion loss information for each antenna of the plurality of antennas. The insertion loss information indicates at least a power difference for each of the plurality of antennas at the UE.

Abstract: During a positioning session in which multiple location reports are provided, a user equipment (UE) that has little or no movement may provide an indication to an entity in the wireless network that there is no update for one or more location measurements. The UE may provide the indication to a serving base station in a Physical layer waveform. The base station may bypass the location server and provide an indication to an external client that the UE position has not changed. The UE may provide the indication to a location server in a location information report or by not sending a location information report by an expiration time. The indication of no update may be provided by a bit that indicates no location measurements are updated or that a particular location measurement is not updated.
