Abstract: 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.

Abstract: Techniques are disclosed for supporting positioning of a target user equipment (UE) that accesses a wireless network via a mobile base station relay (MBSR). The MBSR functions as an Integrated Access and Backhaul (IAB) node accessing the wireless network via a donor base station. The MBSR receives a request for positioning information from a location server via the donor base station related to positioning of the target UE. After determining the positioning information by performing positioning functions of a base station, the MBSR returns the positioning information to the location server via the donor base station, where the positioning information enables positioning of the UE. The location server determines a location of the target UE based at least partially on the positioning information received from the MBSR.

Abstract: A user equipment (UE) accesses a public land mobile network (PLMN) and obtains an address of a server and authorization data. The UE sends the server a request for coverage data based on the address and including the authorization data. After verifying the authorization data, the server sends the coverage data to the UE, which enables the UE to determine whether access to the PLMN is possible at one or more locations of the UE, at one or more future times, and using one more radio access technologies (RATs), including non-terrestrial network (NTN) RAT(s) and/or terrestrial network (TN) RAT(s). The authorization data may include a temporary identifier for the UE that may be ciphered and may enable verification of the authorization data. The request for coverage data may indicate signal levels needed by the UE to access the NTN and TN RATs and the locations and the future times.

Abstract: Methods and apparatus are described for reducing end-to-end latency for location determination of a user equipment (UE). Location requests from an external client for a UE may be supported using control plane signaling. Location reports to the external client may be supported with user plane signaling to minimize delay. An event report with location information may be sent using user plane signaling to the external client (or Application Function) directly or via a Location Management Function (LMF) or Gateway Mobile Location Center (GMLC) or via both the LMF and GMLC. If the LMF or GMLC receive an event report from the UE, the LMF or GMLC may send the event report to the external client with user plane signaling. A periodic or triggered cumulative event report may be sent to the LMF, GMLC or external client using control plane signaling to confirm the periodic or triggered location request remains operational.

Abstract: A method of measuring positioning signals at a user equipment (UE) includes: obtaining, at the UE, one or more transmission characteristics corresponding to each of a plurality of positioning signals; obtaining, at the UE, topographic information regarding physical features of a region associated with the UE and the plurality of positioning signals; determining, at the UE, one or more selected positioning signals, of the plurality of positioning signals, to measure based on the one or more transmission characteristics and the topographic information; and measuring, at the UE, the one or more selected positioning signals to produce one or more measurements.

Abstract: Latency in location of a user equipment (UE) is reduced by requesting and scheduling the location of the UE in advance of the time of when it is needed. A positioning request from an external client or the UE may indicate the time that the location is to be determined or measured. A location management function (LMF) may manage and coordinate location measurements for the UE prior to the location determination time. The LMF may schedule downlink and/or uplink measurements to be performed at the desired time. Either the LMF or a location server associated with a serving base station for the UE may be assigned to receive positioning measurements and obtain the location of the UE. The location server or LMF may send the location to the UE or the external client. User plane transport may be used to further reduce latency.

Abstract: The location of a user equipment (UE) is determined at a scheduled location time based on location measurements for the UE received from one or more other entities. The location measurements are obtained at a plurality of times based on the scheduled location time. An uncertainty of the location that indicates a difference between the location and an actual location of the UE at the scheduled location time is determined and the location and the uncertainty of the location are sent to a requesting entity. The uncertainty of the location is based on a location uncertainty and a time uncertainty relative to the scheduled location time, which are combined into a single location uncertainty.

Abstract: Disclosed are techniques for communication. In an aspect, a first network entity receives an integrated access and backhaul (IAB) node information message from a second network entity, the IAB node information message including one or more parameters for at least one transmission-reception point (TRP) of a base station, wherein the at least one TRP corresponds to an IAB node, and wherein the one or more parameters are related to the at least one TRP corresponding to the IAB node, and performs one or more positioning operations based on the one or more parameters to locate a target user equipment (UE) engaged in a positioning session with a location server.

Abstract: Techniques are discussed herein for efficiently supporting broadcast of location assistance data (AD) in a wireless network to assist in locating a user equipment (UE). A location server (LS) may send some location AD, which may be optionally ciphered, to base stations for broadcast in cells supported by the base stations. Capability information provided by a UE to the LS indicating a level of support by the UE for receiving broadcast AD and supporting ciphering may enable the LS to determine whether, and what type of, additional AD needs to be sent to the UE by point to point means. An LS may use capability information received from a large number of UEs to assist in determining the types of location assistance data to be broadcast and usage of ciphering.

Abstract: Disclosed are techniques for determining round-trip times (RTTs) between a user equipment (UE) and multiple base stations. In an aspect, the UE transmits an RTT measurement signal whose arrival time is measured by each of the base stations, and each of the base stations returns an RTT response signal whose arrival times are measured by the UE. In another aspect, the base stations each transmit an RTT measurement signal and the UE returns an RTT response signal. The receiver of the RTT measurement signal may include the measured arrival time in a payload of the RTT Response signal. Alternatively, the measured arrival time(s) of the RTT Measurement signal(s) and the transmission time(s) of the RTT Response signal(s) are sent in a separate message. The RTT signals can be wideband signals using low reuse resources.
