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: A communication system including a UE, a base station, and a PLMN is disclosed. The UE may access a radio cell supported by a communication satellite. The UE may select a preferred PLMN for each of multiple potential geographic locations of the UE. The UE may transmit, to the base station via the radio cell and the communication satellite, an indication of the preferred PLMN for each of the multiple potential geographic locations of the UE. The base station may attempt to determine a current geographic location of the UE. The base station may determine a serving PLMN as the preferred PLMN for the current geographic location of the UE and may later determine a second PLMN if the current geographic location changes. The base station determination may not be visible to the UE which may reduce UE signaling and resource usage.

Abstract: Techniques described herein provide means by which cell information indicative of a location of a UE may be conveyed to a location server over a 5G NR data connection using a SUPL message with an LTE cell ID data field. In some embodiments, for example, the UE may include the Cell ID of a LTE neighbor cell or information regarding a 5G NR serving cell, such as a portion of the 5G NR Cell ID or a reserved value or sequence identifying the 5G NR serving cell. The techniques may be applicable to the Secure User Plane Location (SUPL) solution defined by OMA and may enable a UE and a SUPL Location Platform (SLP) to support location of the UE using a version of SUPL without explicit support of 5G NR wireless access.

The enhancements allow the LMF to interact with just one UE of the group of UEs and for an LCS Client or AF to indicate a preference for the one UE.

Abstract: In some implementations, a server may obtain wireless network coverage information from crowdsourcing devices, where the wireless network coverage information indicates characteristics of wireless network coverage at different locations along various routes of travel. The server may determine a wireless coverage map of an area based on the wireless network coverage information, where the wireless coverage map comprises, for locations along one or more routes of travel within the area, a respective wireless coverage indication indicative of a level of wireless coverage for wireless networks at the respective location. The server may send route-based coverage information to a mobile device for a particular route, where the route-based coverage information includes the respective wireless coverage indication, from the coverage map, for one or more locations along the particular route.

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: Disclosed are techniques for communication. In an aspect, a location server receives, from a network entity serving a reference device, a registration request for the reference device to operate as a reference location device (RLD), the registration request including one or more parameters enabling the location server to communicate with the reference device via a positioning protocol, instigates a positioning procedure with the reference device via the positioning protocol based on the one or more parameters; receives one or more reference positioning measurements from the reference device during the positioning procedure via the positioning protocol; and determines one or more correction terms for positioning one or more user equipments (UEs) based, at least in part, on a location of the reference device and the one or more reference positioning measurements.

Abstract: The positioning capabilities of a User Equipment (UE) are stored in a core network to reduce positioning latency when the UE indicates that its positioning capabilities are stable and/or are long term valid. The UE may provide its positioning capabilities to a location server during a location session along with an indication of whether the positioning capabilities are stable. The location server may enable storage of the positioning capabilities for the UE in the core network, e.g., in the location server or another entity in the core network such as Access and Mobility Management Function (AMF), if there is an indication that the positioning capabilities are stable. The AMF may include a UE identifier in location requests with which the location server may retrieve the UE positioning capabilities if stored at the location server or may include the UE positioning capabilities if stored at the AMF.

Abstract: In some implementations, a user equipment (UE) may exchange a plurality of sidelink (SL) positioning protocol (SLPP) messages with other UEs in a plurality of UEs, where the plurality of SLPP messages are exchanged via direct wireless SL communications. At least one message of the plurality of SLPP messages may comprise a Request Capabilities message, a Provide Capabilities message, a Request Assistance Data message, a Provide Assistance Data message, a Request Location Information message, or a Provide Location Information message. The UE may perform the positioning based, at least in part, on the plurality of SLPP messages. The UE may further exchange SLPP messages with a location server (e.g. LMF) which may assist the UE to perform the positioning and may enable the location server to obtain location results for the plurality of UEs. SLPP procedures may be defined to manage the SL positioning.

Abstract: Sidelink positioning of a plurality of UEs may be performed using a sidelink (SL) positioning protocol (SLPP) in either a session mode or a sessionless mode. In the session mode, one UE in the plurality of UEs may discover the other UEs, determine a session for SLPP, indicate the session to the other UEs, and exchange a plurality of SLPP messages with the other UEs, where the SLPP messages are part of the session and enable the sidelink positioning. In the sessionless mode, a UE may not discover some or all other UEs in the plurality of UEs and may exchange a plurality of SLPP messages with the other UEs, where the SLPP messages are not part of a session but enable the sidelink positioning. The two modes may each apply to SL positioning using SL PRS signals as well as WiFi, UWB and GNSS signals.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may access a serving network via a satellite while in a first state with the serving network, the first state comprising a connected state. The UE may transmit, to the serving network and based on a determination that a coverage gap associated with the satellite is upcoming, a coverage gap indication that indicates that the coverage gap is upcoming. The UE may transition from the connected state to a second state at or before a start of the coverage gap. Numerous other aspects are described.

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.
