Abstract: Methods and techniques are described for initiating a periodic and triggered location in a target UE. After an LCS Client requests initiation of periodic and triggered location reporting from the UE, two intermediate responses are returned by a network. A first response indicates that the periodic and triggered location request has been received and accepted by the network. A second response indicates that periodic and triggered location has been activated in the UE. Additionally, a periodic and triggered location request may include a maximum event sampling interval and a maximum reporting interval and one or more location triggers. The maximum event sampling interval can limit UE power consumption and the maximum reporting interval can detect when periodic and triggered location is no longer active in a UE. The location triggers may include periodic reporting, reporting using area events or reporting based on UE motion.

Abstract: Methods and techniques are described for supporting location services for a user equipment (UE) that is using Narrowband Internet of Things radio access or Cellular Internet of Things features to access a wireless network. The techniques include enabling support for a last known location of a UE, using previously obtained location measurements, when a UE is not reachable from a wireless network for positioning. The techniques also include limiting positioning protocol interaction between a UE and a location server via a reduced maximum message size, reduced message volume and longer response and retransmission timers. The techniques further include enabling a UE to obtain location measurements when not connected to a wireless network, enabling periodic and triggered location of a UE in which a UE evaluates location triggers while not connected to a wireless network, enabling use of deferred location and enabling improved location security.

Abstract: Methods and techniques are described for supporting location services for a user equipment (UE) using a location server and service based interfaces (SBIs) and SBI service operations in a Fifth Generation wireless network. The location server may be, e.g., a Location Management Function (LMF). 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 receive a location service request for the UE using an SBI and may communicate with another entity in the network, through a second entity and using an SBI, to obtain location information for the UE measured by the other entity. The LMF may determine a location for the UE based on the location information.

Abstract: Techniques are provided for reducing the delay in accumulating positioning measurements and improving positioning latency. An example method for reducing positioning measurement latency in a wireless network includes receiving assistance data including configuration information for a plurality of positioning reference signals, determining measurement gap requirements, requesting measurement gaps based on the measurement gap requirements, receiving measurement gap configuration information, determining a mobility state, and measuring or transmitting one or more positioning reference signals based at least in part on the measurement gap configuration information and the mobility state.

Abstract: A mobile station performs Observed Time Difference of Arrival (OTDOA) positioning by measuring a time of arrival (TOA) of downlink signals transmitted from a reference cell and one or more neighbor cells. Reference Signal Time Differences (RSTDs) are generated using TOA measurements from the reference cell and each neighbor cell. The mobile station reports to a location server location information, including the RSTD measurements and the times of measurement for the TOA measurements. The mobile station may further generate and report additional RSTD and/or TOA measurements and associated times of measurement for the reference cell and/or neighbor cells. A location server may use the RSTD measurements, the times of measurement and any TOA measurements to determine a position of the mobile station taking into account user motion and base station clock drift and/or may adjust the uncertainty of the resulting position.

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.

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 method of coordinating positioning signaling includes: sending, from a user equipment (UE), a request wirelessly for positioning service; receiving, at the UE, an indication of UE positioning signal times for sending UE positioning signals; and sending, from the UE, the UE positioning signals at the UE positioning signal times.

Abstract: Disclosed are techniques for determining round-trip time (RTT) of a user equipment (UE). In an aspect, each gNodeB in a plurality of gNodeBs measure signaling data related to an uplink RTT reference signal received from the UE and the downlink RTT reference signal transmitted by each gNodeB. The signaling data comprises one of a processing delay between a time of arrival (TOA) of the uplink RTT reference signal and a time of transmission (TOT) of the downlink RTT reference signal or a total RTT between the TOT of the downlink RTT reference signal and the TOA of the uplink RTT reference signal. The signaling data is sent to a single entity, other than the UE, e.g., another gNodeB or a location server, where signaling data relevant to the UE is aggregated. The aggregated signaling data may be sent to the UE to determine the RTT for the UE or used by the location server to determine the RTT for the UE.

Abstract: During a positioning session, a user equipment (UE) is provided with an early uplink grant to respond to a request for location service information from a location server. The location service information, for example, may be a request for positioning capabilities, a request for positioning measurements or a position estimate, and may be a request for a single, periodic or triggered location information. The early uplink grant may be requested by the UE prior to needing the uplink grant, e.g., before the positioning measurements have been completed. The location server may instigate the early uplink grant, e.g., at or near the same time that the location server sends the request for information to the UE. The early uplink grant may be used, e.g., during high priority or emergency related positioning sessions, in order to reduce delay in the UE providing a response to the request for location information.
