Abstract: Techniques are provided for transmitting Positioning Reference Signals (PRSs) in cells supporting two different Radio Access Technologies (RATs), where the two RATs (e.g. 4G LTE and 5G NR) employ dynamic spectrum sharing. To avoid interference between the PRSs and between the two RATs, the PRSs may be time aligned to the same set of PRS positioning occasions, and may be assigned orthogonal characteristics such as different muting patterns, orthogonal code sequences, different frequency shifts or different frequency hopping. UEs supporting both RATs may be enabled to measure PRSs for both RATs. UEs supporting only one RAT (e.g. 4G LTE) may be enabled to measure PRSs for just this RAT. A location server such as an LMF, E-SMLC or SLP may provide assistance data to UEs, and request measurements from UEs, for PRSs in one or both RATs.

Abstract: Methods of assisting an emergency situation at a first User Equipment (UE) may comprise detecting the emergency situation; and sending an Emergency Services (ES) request comprising discovery information, wherein the ES request is sent by broadcast using a Long Term Evolution (LTE) Direct service, a WiFi Direct service, or a Peer-to-Peer (P2P) service. Disclosed embodiments also pertain to methods of assisting an emergency situation at a first UE, wherein the method is performed on a second UE and comprises receiving from the first UE an ES request comprising the discovery information for the first UE, wherein the ES request is received using an LTE Direct service; a WiFi Direct service or a P2P service. Disclosed embodiments further pertain to methods of communicating by first UE and/or second UE with a Public Safety Answering Point (PSAP) in order to assist discovery of the second UE by the first UE.

Abstract: Techniques are discussed herein for supporting periodic or triggered location of a user equipment (UE) using control plane (CP) optimization with optional use of 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 CP optimization. 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 association with a RAN node to send the event report using CP optimization and optionally using EDT. The RAN node may then release the signaling association after the LS returns a single response to the UE.

Abstract: Location services may be provided for user equipment (UE) devices in a radio access network (RAN) such as a Fifth Generation (5G) RAN. Location services may be supported by separate positioning domains that may include a Device to Device domain, a RAN domain and a core network (CN) domain. The RAN domain may include a location server function (LSF) that may support positioning services autonomously within the RAN or in collaboration with a D2D or CN domain. The CN domain may include a location server (LS) that may support control plane and/or user plane location. The RAN domain may enable high volume and low latency location service whereas the CN domain may enable high accuracy service and services for external clients.

Abstract: Techniques are provided for positioning of a mobile device in a wireless network using directional positioning reference signals (PRS), also referred to as PRS beamforming. In an example method, a plurality of directional PRSs are generated for at least one cell for a base station, such that each of the plurality of directional PRSs comprises at least one signal characteristic and a direction of transmission, either or both of which may be distinct or unique. The plurality of directional PRSs is transmitted within the at least one cell, such that each of the plurality of directional PRSs is transmitted in the direction of transmission. A mobile device may acquire and measure at least one of the directional PRSs which may be identified using the associated signal characteristic. The measurement may be used to assist position methods such as OTDOA and ECID and to mitigate multipath.

Abstract: Techniques are described for providing assistance data corresponding to a plurality of access points (APs). The techniques include, in part, providing assistance data to a mobile device. The assistance data comprises group data that is common among the plurality of APs. The group data is associated with a group identifier (ID). The techniques further include providing the group ID and a set of AP-specific information for at least one of the plurality of APs. The group data may include information corresponding to a common grid, common location area and/or common characteristics of the APs.

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: Angle of arrival (AOA) and differential AOA (DAOA) positioning for a user equipment (UE) is enhanced by using the UE's inertial sensors to track UE motion and change in angular UE orientation. UE location may be computed, by the UE or a location server, using triangulation for AOA measurements relative to a global reference frame or using multilateration for DAOA measurements. The computed UE location may remain accurate even when the UE is moving while obtaining measurements. The UE can also use AOA and DAOA measurements using 3D angles to increase accuracy when the UE and measured base stations are not in the same horizontal plane. 3D angles can also be used to identify whether the UE is close to a serving base station to improve accuracy further. Various non-AOA measurements may also be used to supplement AOA and DAOA measurements.

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: 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.
