    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: Disclosed are techniques for determining a distance (or range) between a first wireless entity and a second wireless entity. In an aspect, the first wireless entity transmits a first positioning reference signaling (PRS) signal to the second wireless entity at a first time, where the first PRS signal is received by the second wireless entity at a second time, and receives a second PRS signal from the second wireless entity at a third time, where the second PRS signal is transmitted by the second wireless entity at a fourth time. The first wireless entity enables the distance to be determined by a location computing entity, for example, by a location server, based on the first, second, third, and fourth times. The first wireless entity may be a mobile device or a base station and the second wireless entity may be the other of the mobile device or base station.

    Abstract: Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) receives, from a transmission point, a first positioning reference signal (PRS) muting pattern for a first subgroup of PRS resources of a first PRS resource set, wherein the first PRS muting pattern comprises a plurality of N bits representing a plurality of N PRS occasions of the first subgroup of PRS resources, wherein each bit of the plurality of N bits represents a corresponding PRS occasion of the plurality of N PRS occasions of each PRS resource of the first subgroup of PRS resources, and wherein the plurality of N PRS occasions comprises a plurality of active PRS occasions of the first subgroup of PRS resources, and measures, during at least one of the plurality of active PRS occasions of the first subgroup of PRS resources, PRS received from the transmission point.

    Abstract: A RAN location server function (e.g. for 5G New Radio), referred to as Location Management Component (LMC), may be included in a gNB and connected to a gNB Central Unit (gNB-CU). The gNB-CU may receive a location request for a UE (e.g. from an AMF) and may initiate a location session for the UE, including selecting an LMC for the location session. The gNB-CU may handover the UE to a new serving gNB during the location session. The LMC for the location session may then remain unchanged after the handover or may be changed to a new LMC to suit the new serving gNB. The location session may then continue using the original LMC if not changed or the new LMC if changed.

    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.
