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.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for on-demand positioning. For example a method may include transmitting a request to participate in a UE positioning procedure, wherein the request indicates one or more parameters to be used by a location server in coordinating one or more base stations (BSs) to participate in the UE positioning procedure, and receiving signaling from the location server configuring the UE to participate in the UE positioning procedure.

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.

In an aspect, a user equipment (UE) measures one or more positioning reference signal (PRS) resources of at least one PRS instance, and processes the one or more PRS resources of the at least one PRS instance during a PRS processing gap, wherein the PRS processing gap comprises a period of time during which the UE prioritizes PRS processing over reception, processing, or both of other downlink signals and channels.

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.
