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: Techniques are discussed herein for providing on-demand positioning reference signals (PRS) to user equipment (UE). An example method for determining a location of a user equipment according to the disclosure includes receiving a first assistance data associated with a first positioning reference signal configuration, transmitting a request to modify one or more parameters of the first positioning reference signal configuration, receiving a second assistance data associated with a second positioning reference signal configuration, wherein the second positioning reference signal configuration is based at least in part on the request to modify the one or more parameters of the first positioning reference signal configuration, obtaining measurements from one or more positioning reference signals based at least in part on the second assistance data, and determining the location based at least on part on measurements obtained from the one or more positioning reference signals.

Abstract: Positioning of a UE is supported in a Radio Resource Control (RRC) Inactive state. The UE receives from a location server a request for periodic or triggered location and an indication of whether uplink, downlink, or uplink and downlink positioning will be used for subsequent location reporting events when the UE is in the RRC Inactive state. When an event is detected, the UE sends a first event report and a second event report to the location server to report the event and enable UE location while the UE is in the RRC Inactive state. The event reports are each sent with Small Data Transmission (SDT). The first event report may include a Request Assistance Data message indicating a request for an uplink (UL) Positioning Reference Signal (PRS) configuration and the second event report may include location measurement performed by the UE.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) performs a plurality of positioning measurements of a plurality of positioning reference signals (PRS) transmitted by at least one network node, transmits a first physical layer message having a fixed payload size, wherein the first physical layer message includes at least an indication of a type, a number, or both of a first set of positioning measurements of the plurality of positioning measurements to be included in a second physical layer message having a variable payload size, and transmits the second physical layer message having the variable payload size, wherein the second physical layer message includes at least the first set of positioning measurements, and wherein the variable payload size of the second physical layer message is based at least on the type, the number, or both of the first set of positioning measurements.

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: Methods and systems for wireless communication are provided. In one example, a method comprises: receiving, by a mobile device, a radio beam, the radio beam being a directional beam that propagates along an angle of departure with respect to an antenna that transmits the radio beam; identifying, by the mobile device, at least one of: the radio beam or a base station that operates the antenna; determining, by the mobile device, a position of the mobile device based on identifying at least one of the radio beam or the antenna of the base station; and outputting, by the mobile device, the position of the mobile device.

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.
