Abstract: During a positioning session between a user equipment (UE) and a location server, the location server may send the base station a request to suspend the Radio Resource Control (RRC) connection with the UE. For example, the location server may send a request to the base station recommending suspension of the connection or may provide an indication of the amount of time during which position related messages between the UE and the location server are not expected. The base station may determine whether to suspend the connection with the UE, thereby placing the UE in an inactive state based on the information provided. The base station may further determine whether to suspend the connection based on data activity of the UE. While in an inactive state, the UE and base station store UE connection context, which may be used to quickly resume the connection.

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: Uplink high efficiency location of a user equipment (UE) includes initiating periodic or triggered location in the UE by a location server (LS) in a wireless network. The UE enters an idle state and monitors for triggering events. After detecting an event, the UE transmits an uplink positioning signal (UPS) to a base station, where the UPS encodes UPS data comprising a UE ID, an ID for the LS, an authentication code (AC) and location measurements. UPS transmission occurs in an uplink positioning occasion shared with other UEs. The location measurements may be ciphered but other UPS data is unciphered. The base station obtains additional location measurements and transfers the UPS data and the location measurements to the LS. The LS authenticates the UE ID using the AC, determines the UE location using the location measurements and transfers the location to an external client.

Abstract: Methods and techniques are described for supporting location services for a user equipment (UE) in a Fifth Generation wireless network using a Location Management Function (LMF) based control plane (CP) location solution. The LMF serves as the main anchor point for location support instead of an Access and Mobility Management Function (AMF). The LMF may be in either a serving Public Land Mobile Network (PLMN) for a UE or in a Home PLMN for a roaming UE. The LMF may obtain location information for a UE via an AMF from a Next Generation Radio Access Network or the UE and may interact with a Gateway Mobile Location Center to receive location requests from and return location information to an external client. The LMF solution may be more efficient and require less implementation than an AMF based CP location solution.

Abstract: In some implementations, a user equipment (UE) may implement a ranging support protocol layer comprising one or more ranging support elements. The UE may communicate, using the one or more ranging support elements of the ranging support protocol layer, with a corresponding ranging support protocol layer in one or more other UEs, wherein the communicating is conducted via at least one lower protocol layer implemented at the UE. The UE may provide, at the ranging support protocol layer, a positioning service to an upper protocol layer implemented at the UE, the positioning service based at least in part on the communicating.

Abstract: According to embodiments, an example method of positioning a user equipment (UE) by a location server in a wireless communications network, the method may comprises receiving a request to perform positioning of the UE and receiving a notification from a first base station indicating that a transmission path between the first base station and the UE is via an intelligent reflecting surface (IRS). The method may further comprise responsive, at least in part, to receiving the notification, preventing the positioning of the UE from being based on a reference signal transmitted through the transmission path between the first base station and the UE.

Abstract: Techniques are described for securely locating a user equipment (UE). Positioning measurements from the UE, which may be spoofed or not spoofed, are received by a location server, and used to determine a location uncertainty, which is used to determine whether the positioning measurements may be spoofed. The location uncertainty, for example, may be compared to an expected location uncertainty for positioning measurements that are not spoofed. If the location uncertainty is greater than the expected location uncertainty by more than a predetermined threshold, the positioning measurements may be spoofed. Positioning assistance data provided to the UE including information related to transmission times and transmission locations for positioning signals may be incomplete or inaccurate. Spoofed positioning measurements generated by a UE based on the incomplete or inaccurate information will include errors that produce a relatively large uncertainty compared to actual positioning measurements for which uncertainty would be smaller.

Abstract: During positioning of a user equipment (UE), for example, during an emergency call, a civic location of the UE may be determined. For example, during a location session in a wireless network, a UE may detect a WiFi access point (AP) and obtain the civic location of the WiFi AP from the AP. The UE may provide the civic location to a location server in the wireless network, which may treat the civic location as the civic location of the UE. The location server may validate the civic location using a geodetic location, e.g., obtained based on measurements from a satellite positioning system and/or base stations in the wireless network. The location server may further verify that the UE is proximate to the WiFi AP using WiFi positioning measurements performed by the UE. The validated civic location can be provided to an external client, e.g. a PSAP.

Abstract: A method of wireless communication by a user equipment (UE) includes determining whether the UE transitioned between an international area and a national area. The method also includes triggering a public land mobile network (PLMN) selection of a network for receiving service, in response to the UE having transitioned between the international area and the national area. A method of wireless communication by a UE includes performing a PLMN search for a higher priority PLMN. The method also includes determining a list of candidate PLMNs based on the search. The method further includes selecting a PLMN from among the list of candidate PLMNs in response to an identity of a serving PLMN not being a shared mobile country code (MCC). The candidate PLMNs have either an MCC the same as an identity of the serving PLMN or a shared MCC. The selected PLMN has a higher priority than the serving PLMN.

Abstract: Techniques are described to support call routing and location for a user equipment (UE) with satellite wireless access to a serving PLMN. The UE sends a Session Initiation Protocol (SIP) INVITE message to a network node, such as a P-CSCF, that includes an indication of satellite access for the UE. In response the network node sends a request to another network node for a cell ID for a fixed cell in which the UE is located. The fixed cell can be independent of satellite radio cells for the serving PLMN. The network node may receive the cell ID for the fixed cell and sends the SIP INVITE message to another network node (e.g., an E-CSCF or LRF) with the cell ID for the fixed cell. The other network node may use the cell ID to route the SIP INVITE message or obtain an approximate location of the UE.
