Abstract: A mobile device supports positioning with positioning reference signals (PRS) on multiple beam by dividing the PRS processing into two separate modes, an acquisition mode and a tracking mode. In acquisition mode, the mobile device performs a fast scan of all of the beams from a base station transmitting PRS using less than the full set of resources for the PRS, i.e., less than the full bandwidth and/or less than the full number of repetitions of the PRS. The mobile device may select the best beams to use for positioning, e.g., based on signal strength metric. In tracking mode, the mobile device tracks the PRS from only the selected beams using the full set of resources for the PRS. The mobile device may return to acquisition mode after a predetermined number of positioning occasions or if the selected beams are no longer valid due to movement or change in conditions.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) receives, from a location server, a positioning reference signal (PRS) configuration for a downlink-and-uplink-based positioning session between the UE and the location server, waits, based on a determination that a sounding reference signal (SRS) configuration for the downlink-and-uplink-based positioning session has not been received from a serving base station of the UE, for reception of the SRS configuration from the serving base station until expiration of a timer, and determines, based on the expiration of the timer, whether the SRS configuration was received.

Abstract: Disclosed are techniques related to wireless communication system in which a network node (e.g., a base station, gNB, etc.) may be allowed to puncture a reference signal (RS) to deliver high priority data (e.g., URLLC data) to a user equipment (UE) that is not currently being served by the network node. The RS may comprise a puncturable subset and an unpuncturable subset. The puncturable subset may comprise resources of the RS that are allowed to be punctured, and the unpuncturable subset may comprise resources of the RS that are prohibited from being punctured. The network node may transmit the RS such that unpuncturable subset indicates whether or not the puncturable subset of the RS has or has not been punctured.

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.

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: A mobile device and base station are enabled to support improved positioning accuracy in the presence of phase noise in high frequency radio network, such as in 5G New Radio network operating in mmWave. Phase Tracking Reference Signal (PTRS) may be transmitted with Positioning Reference Signals (PRS) and used for positioning and/or used to correct the phase offset between symbols in the PRS. A request may be made to transmit PTRS alone or with the PRS, or that the PRS is transmitted with a specific PRS frame structure, e.g., with a specific comb value, that minimizes the impact of phase noise. The PTRS or a phase ramp of the staggered symbols in the PRS may be used to estimate and correct the phase offset. Less than all of the symbols transmitted in the PRS may be used to generate positioning measurements to minimize the impact of phase noise.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a UE transmits, at a first time during a measurement window for positioning purposes, a first uplink reference signal in accordance with a first timing adjustment parameter, wherein the first time is offset from a downlink frame time of a base station by an amount of the first timing adjustment parameter, determines whether to use a second timing adjustment parameter, transmits, in response to the determination to use the second timing adjustment parameter, at a second time during the measurement window, a second uplink reference signal in accordance with a second timing adjustment parameter, wherein the second time is offset from the downlink frame time of the base station by an amount of the second timing adjustment parameter, and transmits a report indicating that the second timing adjustment parameter has been applied to at least the second uplink reference signal.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) receives at least one positioning reference signal (PRS) resource from a reference transmission-reception point (TRP) and one or more neighboring TRPs, and processes the at least one PRS resource during a time window, wherein a length of the time window is less than or equal to an integer number of orthogonal frequency division multiplexing (OFDM) symbols of the at least one PRS resource that the UE is capable of processing, buffering, or both within the time window.
