Abstract: A RAN location server function (e.g. for 5G New Radio), referred to as Location Management Component (LMC), may be included in a gNB and connected to a gNB Central Unit (gNB-CU). The gNB-CU may receive a location request for a UE (e.g. from an AMF) and may initiate a location session for the UE, including selecting an LMC for the location session. The gNB-CU may handover the UE to a new serving gNB during the location session. The LMC for the location session may then remain unchanged after the handover or may be changed to a new LMC to suit the new serving gNB. The location session may then continue using the original LMC if not changed or the new LMC if changed.

Abstract: Positioning assistance data (PAD) may be partitioned into positioning System Information Blocks (posSIBs) and periodically broadcast by a base station. A posSIB or scheduling information for a posSIB may include a validity time and a validity tag that indicates whether the PAD for a posSIB has changed. A user equipment (UE) may receive a posSIB comprising PAD and the validity time and the validity tag for the posSIB. The UE may then wait until the validity time expires and/or the validity tag in the scheduling information indicates a change of PAD before receiving a new instance of the posSIB. The validity time and validity tag may both be included in the posSIB, in which case the UE may receive the posSIB and then look at the validity tag to determine whether to decode and process the PAD.

Abstract: A wireless network including user equipment (UE) and base stations is configured to perform position determination with low latency and synchronized to a common time within a wireless network. The UE and base stations are configured to perform positioning measurements at a specific time point or within a window around the time point in a measurement period. The time point may be relative to a timing event within the wireless network, such as the beginning or end of a positioning reference signal window or a specific message in a layer 1 or layer 2 transmission. A location server may be provided with the positioning measurements or a position estimate from the UE and provide the position estimate to an external client within the measurement period.

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: Access, mobility management and regulatory services are supported for satellite access to a 5G core network. Radio cells supported by a satellite may be moving as the satellite moves and may undergo changes, e.g. when a satellite is transferred from one earth station to another. A base station may broadcast a remaining lifetime for a radio cell (e.g. in a system information block) which indicates to UEs how much longer the radio cell can be accessed before a change occurs. A radio cell may also indicate support for one or more fixed tracking areas (TAs) in coverage of the radio cell. A base station may broadcast a remaining lifetime for each TA to indicate to UEs how much longer a TA will be supported by the radio cell. UEs can use the indications to perform cell change or handover to other radio cells and/or other satellites.

Abstract: Techniques are discussed herein for supporting periodic or triggered location of a user equipment (UE) using Early Data Transmission (EDT). A location server (LS), such as a 5G LMF, sends a request to a UE for periodic or triggered location and includes a request and/or criteria for using EDT. After confirming the request, the UE monitors for periodic or triggering events and, for each detected event, sends an event report to the LS which may include location information. In embodiments, the UE establishes a signaling connection with a RAN node but not with a core network to send the event report using EDT. The RAN node may then release the signaling connection, either immediately or after the LS returns a single response to the UE.

Abstract: Methods and techniques are described for supporting different location solutions in a wireless network (e.g. a 5G network) in which two different location solutions coexist in the same wireless network, and where a network operator may migrate network support from one location solution to the other. For location support of emergency calls, handover of an emergency call can be supported from a network node (e.g. an AMF) that supports one location solution to a network node (e.g. another AMF) that supports the other location solution. The handover may be supported by transferring indications of the handover between network nodes (e.g. including a GMLC, AMF and/or an LMF) to enable reconfiguration of location support for the emergency call at an LRF and GMLC from one location solution to the other.

Abstract: Techniques are disclosed in which generic position methods in a wireless network allow positioning of a target user equipment (UE) that is served by any one (or more) of a number of different Radio Access Technologies (RATs) and that allow measurements by the UE of access nodes belonging to different RATs and/or measurements of the UE by access nodes for different RATs. With a generic position method, a common set of procedures, messages, and parameters may be defined that are applicable to multiple RATs and that do not require a location server to know in advance the serving RAT for a target UE.

Abstract: Disclosed are methods for aiding a mobile device in the acquisition of positioning reference signals (PRSs) transmitted in a cellular network in support of OTDOA positioning. In one implementation, a mobile device receives an offset parameter from a location server indicative of a difference in timing between transmission of a first PRS positioning occasion for a reference cell and transmission of a second PRS positioning occasion for a neighboring cell that supports multiple PRS configurations, where the second PRS positioning occasion is for a PRS configuration with a longest periodicity. The mobile device may determine an expected timing of PRS positioning occasions for other PRS configurations for the neighboring cell based on the offset parameter and may measure a Reference Signal Time Difference for the neighboring cell using the expected timing.

Abstract: Methods and techniques are described for enhancing positioning related protocols in order to indicate when one location session is different from another location session. One or more messages provided in a location session by a location server to a user equipment (UE) may include a session indication, such as a session identifier (ID), where a different session ID is provided for each location session. The session indication may be a new session indicator provided in an initial message in a location session or an end session indicator provided in a final message in a location session. An extra message may be sent by the location server indicating that the location session has ended. A correlation ID provided by a network entity to the location server may be included in messages as the session indication, e.g., where a different correlation ID is provided for each location session.
