Abstract: A user equipment (UE) is configured for supporting positioning using sounding reference signal (SRS) periodic burst transmissions that includes a plurality of sets of SRS transmissions, where each set of SRS transmissions includes a repetition of SRS resources. The configuration for the SRS periodic burst transmissions includes a start time for the SRS periodic burst transmissions, a repetition configuration for the SRS resources within each set, and a repetition configuration for the plurality of sets of SRS transmissions. The configuration may be received in a Radio Resource Control (RRC) configuration message or a Medium Access Control-Control Element (MAC-CE) message that activates the SRS periodic burst transmissions, and the SRS periodic burst transmissions may be deactivated with a RRC reconfiguration message or another MAC-CE message.

Abstract: Aspects presented herein may enable a UE to store multiple sets of UE processing capabilities at one or more entities, and to activate one of the stored sets based on the UE's current processing availabilities to improve positioning latency. In one aspect, a UE transmits, to at least one of a second UE, a base station, or a network entity, a plurality of capability sets associated with UE positioning processing, the plurality of capability sets including at least a first capability set corresponding to a first level of the UE positioning processing and a second capability set corresponding to a second level of the UE positioning processing, the first level being different from the second level. The UE transmits, to the at least one of the second UE, the base station, or the network entity, an indication to activate one of the plurality of capability sets for UE positioning.

Abstract: In an aspect, a user equipment (UE) may measure one or more positioning reference signals (PRS) transmitted by one or more transmission-reception-points (TRPs). The UE may measure one or more backscattered signals received from one or more ambient Internet-of-things (IoT) anchor devices, wherein the one or more backscattered signals correspond to the one or more PRS received at the one or more ambient IoT anchor devices.

Abstract: In some implementations, a first UE may receive an indication of the positioning session in which the first UE is to participate, wherein the first UE is to participate by sending and/or receiving SL-PRS via an SL communication link with a second UE. The first UE may obtain, with the first UE, the SL PRS DRX configuration for the positioning session, wherein: the SL PRS DRX configuration for the positioning session designates a plurality of DRX cycles during the positioning session, each DRX cycle having a respective ON duration and a respective OFF duration. The first UE may monitor the SL communication link for the positioning information with the first UE in accordance with the SL PRS DRX configuration.

Abstract: Positioning measurements to determine the location of a user equipment (UE) may be obtained within a configured time window, such as a measurement time window or positioning reference signal (PRS) processing window. If one or more position measurements cannot be obtained within the configured window, the measuring entity may provide an error report to the positioning entity indicating that it was unable to obtain one or more positioning measurements within the configured time window. The error message may be provided in the provide location information report. The error message may include the timing of the error within the configured time window, e.g., whether the error occurred at the beginning or end of the configured time window. The error message may further indicate the cause of the error, such as failure to receive a PRS processing window, or that the PRS had low priority relative to downlink signals or channels.

Abstract: A first sensing entity may receive, from a second sensing entity, a sensing information message that may include a first set of sensing attributes associated with a set of objects within an area associated with the first sensing entity. The first sensing entity may transmit a set of sensing signals at a target object. The first sensing entity may receive a set of reflected sensing signals based on the set of sensing signals and the target object. The first sensing entity may measure a second set of sensing attributes associated with the target object based on the set of reflected sensing signals and the first set of sensing attributes. The measured second set of sensing attributes may be more accurate than a set of sensing attributes that are not based on the first set of sensing attributes.

Abstract: Aspects presented herein may improve radio frequency (RF) sensing accuracy for an RF sensing node by enabling the RF sensing node to perform RF sensing using multiple antenna/antenna panels. In one aspect, a UE transmits, to a sensing entity, an indication of a capability to perform RF sensing using a set of antenna panels. The UE receives, from the sensing entity based on the indication, a configuration to perform an RF sensing operation using a subset of antenna panels in the set of antenna panels, where each antenna panel in the subset of antenna panels is configured to perform a corresponding RF sensing operation for each antenna panel. The UE performs, based on the configuration, the RF sensing operation via each antenna panel in the subset of antenna panels.

Abstract: Aspects presented herein may enable a network entity to associate one or more positioning related parameters between a UE and an NTN base station with a scheduling offset, a position of the NTN base station, and/or a time. In one aspect, a network entity identifies a scheduling offset that is associated with an NTN base station. The network entity transmits, to a UE communicating with the NTN base station, one or more of: a set of expected RSTD values associated with the NTN base station, a set of compensation factors associated with the set of expected RSTD values, a set of uncertainty values associated with the set of expected RSTD values, a set of expected DL-AoD values/uncertainties associated with the NTN base station, or a set of expected AoA values/uncertainties associated with the NTN base station, where one or more of these parameters are derived based on the scheduling offset.
