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.

Abstract: An entity in a wireless network is configured to increase transmission of a positioning reference signal (PRS) at each of a plurality of transmitters, where the increase in transmission of PRS at each of the plurality of transmitters is coordinated to avoid interference to or from non-PRS transmission in the wireless network. The increase in the transmission of PRS may be performed by a server, such as a location management function (LMF) or location management component (LMC), a base station, such as a gNB, ng-eNB, or eNB, or by a combination of the server and base station. The entity may determine the increase in transmission of the PRS in response to location requests for a plurality of user equipments (UEs), notification reports from a plurality of base stations, or requests for increased PRS from a plurality of UEs.

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: 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: A UE receives a first configuration for at least one RRM measurement gap. The UE receives one or more PRSs prior to the at least one RRM measurement gap. The UE identifies whether a processing availability of the UE during the at least one RRM measurement gap is sufficient to process the one or more PRSs. The UE processes the one or more PRSs, where in response to the processing availability of the UE during the at least one RRM measurement gap, the one or more PRSs are processed during the at least one RRM measurement gap; and in response to lack of the processing availability of the UE sufficient to process the one or more PRSs during the at least one RRM measurement gap, the one or more PRSs are processed, at least in part, outside of the at least one RRM measurement gap.

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: 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.
