摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) receives, from a serving base station, a medium access control control element (MAC-CE) indicating activation or deactivation of a semi-persistent (SP) sounding reference signal (SRS)-for-positioning, wherein a reserved bit in the MAC-CE or a logical channel identifier (LCID) of a MAC subheader of the MAC-CE indicates the activation or deactivation of the SP SRS-for-positioning, and transmits the SP SRS-for-positioning on one or more SRS resources configured for the UE, the SP SRS-for-positioning having transmission parameters adopted from a spatial relation reference signal for the SP SRS-for-positioning.

摘要： 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.

摘要： 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.

摘要： Disclosed are techniques for scheduling uplink (UL) and downlink (DL) physical layer resources for a serving node and a user equipment (UE) for round trip time (RTT) and observed time difference of arrival (OTDOA) based positioning. In an aspect, a serving node and/or a network entity configure the UL and DL physical layer resources, and inform the UE. A network node transmits RTT measurement (RTTM) signal to the UE and receives RTT response (RTTR) signals from the UE. The network node measures the times the RTTM signals are transmitted and the times the RTTR signals are received. The UE provides to serving node processing times indicating a duration between the UE receiving the RTTM signals and the UE transmitting the RTTR signals. The RTTs are calculated from the times measured by the network node and the processing times provided by the UE.

摘要： Techniques are provided for positioning of a mobile device in a wireless network using directional positioning reference signals (PRS), also referred to as PRS beamforming. In an example method, a plurality of directional PRSs are generated for at least one cell for a base station, such that each of the plurality of directional PRSs comprises at least one signal characteristic and a direction of transmission, either or both of which may be distinct or unique. The plurality of directional PRSs is transmitted within the at least one cell, such that each of the plurality of directional PRSs is transmitted in the direction of transmission. A mobile device may acquire and measure at least one of the directional PRSs which may be identified using the associated signal characteristic. The measurement may be used to assist position methods such as OTDOA and ECID and to mitigate multipath.
