  • Publication number: 20240284528
    Abstract: Disclosed are techniques for sidelink positioning. In an aspect, an initiator user equipment (UE) transmits a first request to create a sidelink positioning protocol (SLPP) session to each recipient UE among a set of one or more recipient UEs, and receives first responses from the set of one or more recipient UEs that each indicate an acceptance or rejection of the SLPP session by the recipient. A group of one or more UEs for participation in the SLPP session is determined by the initiator UE from among recipient UEs from which a respective first response that indicates the acceptance of the SLPP session is received. In another aspect, a UE transmitting an SLPP message may indicate a first casting mode (e.g., unicast, groupcast, broadcast, etc.) of the SLPP message and may optionally indicate a second casting mode (e.g., unicast, groupcast, broadcast, etc.) for response(s) to the SLPP message.

  • Patent number: 12047904
    Abstract: Disclosed are methods and apparatuses for resolving aliasing ambiguities produced when using channel state information reference signal, a sounding reference signal (SRS) or other transmission as a positioning reference signal (PRS) occupying a subset of tones of a PRS bandwidth. The aliasing ambiguity results in a plurality of different possible positioning measurements, such as time of arrival (TOA), reference signal timing difference (RSTD), or reception to transmission difference (Rx?Tx). The aliasing ambiguity may be resolved using a previous position estimate that may be used to produce an approximation of the expected positioning measurement. A position estimate may be generated using a multiple stage PRS configuration, in which one or more stages provide a coarse position estimate that has no ambiguity, which can be used to resolve the ambiguity of a more accurate position estimate resulting from the PRS signal.

  • Patent number: 12047903
    Abstract: This disclosure provides methods, devices, and systems for multi-level configuration and reporting for positioning in new radio (NR) wireless communications systems. In some wireless communications systems, a network entity may determine a position or location of a supported user equipment (UE) using radio access network information. The information may be associated with UE-assisted positioning techniques, such as a positioning reference signal (PRS) transmission by the base station and reporting of radio signaling measurements by the UE. The UE may support a multi-level configuration for reporting the radio signaling measurements, including determined report quantities on one or more of a resource level, a set level, or a setting level for the PRS transmission, or generally for the network entity. The described techniques may improve robustness associated with the reporting and, in some examples, reduce signaling overhead associated with determining a positioning and location of the UE.

  • Publication number: 20240244580
    Abstract: A position of a user equipment (UE) may be determined using downlink based solutions (e.g. OTDOA), uplink based solutions (e.g. UTDOA), or combined downlink and uplink based solutions (e.g. RTT). The serving gNBs may request neighboring gNBs to produce downlink reference signal transmissions to a target UE and/or measure uplink reference signal transmissions from the target UE. The serving gNB may receive the uplink reference signal measurements from neighboring gNBs and obtain an own uplink reference signal measurement and forward to the UE or another network entity all the uplink reference signal measurements. The UE may use the uplink reference signal measurements, along with the UE's own downlink reference signal measurements to determine RTTs. The serving gNBs or another entity may keep the uplink reference signal measurements and may determine RTTs after receiving the downlink reference signal measurements from the UE.

  • Patent number: 12041574
    Abstract: Techniques described herein are directed to improving the positioning of a target user equipment (UE) using an enhanced repeater disposed in a wireless network. In some embodiments, the enhanced repeater may include logically distinct user equipment (UE) functionality and distributed unit (DU) functionality. The UE functionality may enable setup with other entities of the network, e.g., an upstream location management function (LMF), such that the enhanced repeater is recognized as capable of positioning. The DU functionality may enable generation of downlink positioning signals (e.g., DL-PRS) at the enhanced repeater so as to obviate relaying of DL-PRS generated elsewhere in the network. The enhanced repeater may perform uplink measurements based on uplink positioning signals receive from the target UE, and report the uplink measurements to the LMF, enabling the LMF to calculate the position of the UE with fewer errors than if the uplink positioning signals were simply relayed.

  • Patent number: 11997563
    Abstract: A mobile station performs Observed Time Difference of Arrival (OTDOA) positioning by measuring a time of arrival (TOA) of downlink signals transmitted from a reference cell and one or more neighbor cells. Reference Signal Time Differences (RSTDs) are generated using TOA measurements from the reference cell and each neighbor cell. The mobile station reports to a location server location information, including the RSTD measurements and the times of measurement for the TOA measurements. The mobile station may further generate and report additional RSTD and/or TOA measurements and associated times of measurement for the reference cell and/or neighbor cells. A location server may use the RSTD measurements, the times of measurement and any TOA measurements to determine a position of the mobile station taking into account user motion and base station clock drift and/or may adjust the uncertainty of the resulting position.
