Abstract: The positioning capabilities of a User Equipment (UE) are stored in a core network to reduce positioning latency when the UE indicates that its positioning capabilities are stable and/or are long term valid. The UE may provide its positioning capabilities to a location server during a location session along with an indication of whether the positioning capabilities are stable. The location server may enable storage of the positioning capabilities for the UE in the core network, e.g., in the location server or another entity in the core network such as Access and Mobility Management Function (AMF), if there is an indication that the positioning capabilities are stable. The AMF may include a UE identifier in location requests with which the location server may retrieve the UE positioning capabilities if stored at the location server or may include the UE positioning capabilities if stored at the AMF.

Abstract: Disclosed are techniques for signaling of reception-to-transmission measurements from gNBs and user equipments (UEs) for round trip time (RTT) based positioning in wireless networks such as new radio (NR). In multi-RTT positioning, the flow of messages that are exchanged differ depending on the entity acting as the location server determining the position of the UE.

Abstract: In a particular embodiment, a method includes receiving a first set of location data and a second set of location data at a mobile device. The method includes locating a first reference point identifier that is included in the first set of location data and a second reference point identifier that is included in the second set of location data. The first reference point identifier field and the second reference point identifier field identify a common reference point. The method includes identifying first information in the first set of location data that is associated with the common reference point. The method also includes identifying second information in the second set of location data that is associated with the common reference point and spatially aligning the first set of location data with the second set of location data based on the common reference point to associate the first information with the second information.

Abstract: An external client requests the location of a UE using control plane signaling. The UE sends downlink location measurements, such as Reference Signal Time Differences, for a plurality of base stations (BSs) to a serving BS at a layer 1 or layer 2 protocol level and at first periodic intervals. The UE and the plurality of BSs send additional location measurements, such as receive time-transmission time differences, to the serving BS at second periodic intervals, which are longer than the first periodic intervals. The serving BS uses the additional location measurements and downlink location measurements to determine timing information, such as Real Time Differences, for the plurality of BSs. The serving BS determines the location of the UE using the downlink location measurements and the timing information at the first periodic intervals and sends the location to the external client using user plane signaling to reduce delay.

Abstract: In an embodiment, a UE selects between RS collision protocols to selectively monitor, on downlink resource(s) scheduled with overlapping transmissions of first and second RS types, either the first RS type or neither RS type. In another embodiment, a base station determines that a downlink resource(s) are scheduled with overlapping transmissions of first and second RS types, punctures the second RS type, and selectively transmits the first RS type on the overlapped downlink resource(s). In another embodiment, a base station establishes non-overlapping NPRS and eNPRS transmission schedules.

Abstract: Disclosed are techniques for handling of radio frequency front-end group delays (GDs) for round trip time (RTT) estimation. In an aspect, a network entity determines information indicating a network total GD and a user equipment (UE) determines information indicating a UE total GD. The network entity transmits one or more RTT measurement (RTTM) signals to the UE, each including a RTTM waveform. The UE determines one or more one or more RTT response (RTTR) payloads for one or more RTTR signals, each including a RTTR waveform. The UE transmits the RTTR signal(s) to the network entity. For each RTTR signal, a transmission time of the RTTR waveform and/or the RTTR payload is/are determined based on the UE total GD. The network entity determines a RTT between the UE and the network entity based on the RTTM signal(s), the RTTR signal(s), and the information indicating the network total GD.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) engaged in a positioning session with a plurality of transmission-reception points (TRPs) receives a downlink positioning reference signal (DL-PRS) configuration specifying one or more DL-PRS resource sets of a DL-PRS instance, wherein all DL-PRS resources of the one or more DL-PRS resource sets of the DL-PRS instance are scheduled within a time window, and receives an uplink PRS (UL-PRS) configuration specifying one or more UL-PRS resource sets, wherein all of the one or more UL-PRS resources are scheduled within the time window. The UE may perform, during the time window, measurements of DL-PRS transmissions on one or more DL-PRS resources of the one or more DL-PRS resource sets, and transmit, during the time window, at least one UL-PRS on the one or more UL-PRS resources.

Abstract: A wireless network including user equipment (UE) and base stations is configured to perform position determination with low latency and synchronized to a common time within a wireless network. The UE and base stations are configured to perform positioning measurements at a specific time point or within a window around the time point in a measurement period. The time point may be relative to a timing event within the wireless network, such as the beginning or end of a positioning reference signal window or a specific message in a layer 1 or layer 2 transmission. A location server may be provided with the positioning measurements or a position estimate from the UE and provide the position estimate to an external client within the measurement period.

Abstract: This disclosure provides methods, devices, and systems for beam group reporting for positioning in new radio (NR) wireless communications systems. In some wireless communications systems, multiple PRS resources, e.g., a beam group, received by a user equipment (UE) from the same network entity may be used to produce a combined Time of Arrival (TOA) measurement for the reference or target to derive an Reference Signal Time Difference (RSTD) estimate. The UE provides to a network entity an indication of the PRS resources in the beam group, which may be specifically or generally identified. Additionally, parameters associated with the beam group are provided, such as a relative quality of the TOA measurement for each PRS resource in the subset, a spread of the TOA measurements in the subset, a relative signal strength of each PRS resource in the subset, or a spread of the signal strength in the subset.

Abstract: A method of coordinating positioning signaling includes: identifying a first user equipment (UE) served by a base station and a second UE served by the base station, the base station being configured to send a base station positioning signal wirelessly at a plurality of base-station-transmission times; allocating first times to the first UE, for sending first UE positioning signals, and second times to the second UE, for sending second UE positioning signals, at least one of the first times being different from at least one of the second times; sending a first communication to cause the first UE to send at least a respective one of the first UE positioning signals at each of the first times; and sending a second communication to cause the second UE to send at least a respective one of the second UE positioning signals at each of the second times.
