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.

Abstract: Disclosed are various techniques for wireless communication. In an aspect, a user equipment (UE) may receive, from a requesting entity, a request for information relating to a channel condition of the UE. The requesting entity may comprise a base station or a location server, for example. The UE may determine information relating to the channel condition of the UE. The UE may send, to the requesting entity, the information relating to the channel condition of the UE. In some aspects, the UE may receive location assistance data from the requesting entity along with a request to perform a location measurement; the UE may perform the location measurement and send location information to the requesting entity. The location information may comprise a location measurement result, the UE's estimate of its own location, or both.

Abstract: Certain aspects of the present disclosure provide techniques for performing a public land mobile network (PLMN) selection procedure based on allowed PLMN(s) in a particular country of a user equipment (UE). An example method generally includes determining a country in which the UE is located, creating a list of available PLMNs, that are allowed to be selected in the country in which the UE is located, for access to a non-terrestrial network (NTN), and performing a PLMN selection procedure for access to the NTN based on the list of available PLMNs and the country in which the UE is located.

Abstract: Satellite access to a public land mobile network (PLMN) with a Fifth Generation (5G) core network (5GCN) is supported by a serving satellite NodeB (gNB). The gNB determines or verifies a country in which a user equipment (UE) is located to ensure that the UE is located in the same country as the 5GCN. The gNB receives assistance data from a location server and receives UE measurements of DL signals from a plurality of satellites, e.g., GNSS satellites and/or communication satellites. The assistance data may be solicited or unsolicited by the gNB. The gNB uses the UE measurements and assistance data to determine a location and country of the UE. The gNB allows access by the UE to the 5GCN when the country matches a country of the 5GCN and may provide the 5GCN with an indication of whether the country of the UE was verified.

Abstract: Methods and techniques are described for efficiently supporting periodic and triggered location services for a user equipment (UE) in a Fifth Generation wireless network. A serving core network (CN) node, such as an AMF, receives a request for periodic or triggered location for the UE from another CN entity, such as a GMLC, and transfers the request to a location server, such as an LMF, which initiates and establishes the periodic and triggered location session with the UE. The serving CN node then releases all resources for the location request. The UE monitors for periodic or trigger events and reports each event to a location server which forwards an event report, optionally containing a UE location, to an external client via a CN entity, such as GMLC. The event reporting can be efficient because a serving CN node is not materially involved.

Abstract: A user equipment (UE) and a Secure User Plane Location (SUPL) Location Platform (SLP) support a SUPL positioning session for at least one uplink or uplink-downlink position method, such as uplink Angle of Arrival or multi-Round Trip Time. To support SUPL positioning for uplink or uplink-downlink position methods, the UE provides an identifier for a serving Access and Mobility Management Function (AMF) and an identifier for the UE to the SLP in a SUPL message. The SLP may exchange positioning messages with a serving base station for the UE using the identifier for the serving AMF and the identifier for the UE. The exchange of positioning messages may enable the SLP to request the serving base station to instigate transmission of uplink positioning reference signals by the UE which may be a key enabler for an uplink or uplink-downlink position method.

Abstract: An external client requests the location of a UE using control plane signaling. The UE sends downlink location measurements, such as Reference Signal Time Differences, for a plurality of base stations (BSs) to a serving BS at a layer 1 or layer 2 protocol level and at first periodic intervals. The UE and the plurality of BSs send additional location measurements, such as receive time-transmission time differences, to the serving BS at second periodic intervals, which are longer than the first periodic intervals. The serving BS uses the additional location measurements and downlink location measurements to determine timing information, such as Real Time Differences, for the plurality of BSs. The serving BS determines the location of the UE using the downlink location measurements and the timing information at the first periodic intervals and sends the location to the external client using user plane signaling to reduce delay.
