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: A network entity in a wireless network supports routing of an emergency call for a user equipment (UE) to a Public Safety Answering Point (PSAP) based on determining whether Location Based Routing (LBR) is needed according to the serving cell for the UE. LBR may be needed when multiple PSAPs have jurisdiction over the serving cell coverage area, in which case an early location fix, based on early location information from the UE (e.g. obtained using LPP), and a later final location fix may be obtained. The early location fix is used to perform LBR to an appropriate PSAP. The final location fix is more accurate and is provided later to the PSAP for emergency dispatch. If LBR is not needed, the serving cell identity may be used to route the call to the PSAP instead of an early location fix, which can reduce latency.

Abstract: An entity in a wireless network is configured to increase transmission of a positioning reference signal (PRS) at each of a plurality of transmitters, where the increase in transmission of PRS at each of the plurality of transmitters is coordinated to avoid interference to or from non-PRS transmission in the wireless network. The increase in the transmission of PRS may be performed by a server, such as a location management function (LMF) or location management component (LMC), a base station, such as a gNB, ng-eNB, or eNB, or by a combination of the server and base station. The entity may determine the increase in transmission of the PRS in response to location requests for a plurality of user equipments (UEs), notification reports from a plurality of base stations, or requests for increased PRS from a plurality of UEs.

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: In an aspect, to perform inter-frequency measurements by a user equipment (UE) in a carrier aggregation mode, the UE receives assistance data identifying one or more reference signal occasions for one or more neighbor cells, receives information identifying one or more subframes during which the one or more neighbor cells do not carry data transmissions, identifies, for a first reference signal occasion of the one or more reference signal occasions, a first subframe of the one or more subframes that overlaps the first reference signal occasion, tunes, during the first subframe, a first active carrier receiver of a plurality of active carrier receivers away from a first frequency on which the first subframe is transmitted to a second frequency on which the first reference signal occasion is transmitted, and measures, by the first active carrier receiver, the first reference signal occasion on the second frequency during the first subframe.

Abstract: Methods and systems for wireless communication are provided. In one example, a method comprises: receiving, by a mobile device, a radio beam, the radio beam being a directional beam that propagates along an angle of departure with respect to an antenna that transmits the radio beam; identifying, by the mobile device, at least one of: the radio beam or a base station that operates the antenna; determining, by the mobile device, a position of the mobile device based on identifying at least one of the radio beam or the antenna of the base station; and outputting, by the mobile device, the position of the mobile device.

Abstract: Techniques are discussed herein for efficiently providing wireless emergency alerts (WEA) to a mobile device. The techniques include broadcasting a warning message from a base station in a wireless network within a cell for the base station and including an interior cell or exterior cell indication and a geographic area description for an external cell. A receiving mobile device may then display the warning message to a user either unconditionally when an interior cell is indicated or after verifying the mobile device is located within the geographic area for an exterior cell. The wireless network may determine interior versus exterior cell status by determining interior cells to be wholly within the geographic area and exterior cells to be partly within the geographic area.

Abstract: Techniques for supporting positioning for a terminal (sometimes referred to herein as a target device) in a wireless network are described. In an aspect, positioning for a target device includes receiving a Request Location Information message that indicates at least one positioning method from a plurality of supported positioning methods. The Request Location Information message comprises common parameters that are applicable to all positioning methods indicated in the Request Location Information message. The common parameters comprise a quality-of-service (QoS), an indication of whether periodic location information is requested, an indication of whether triggered location information is requested, or any combination thereof. Positioning is performed in response to the Request Location Information message and can include determining a location estimate for a location of the target device.

Abstract: Disclosed are techniques for determining a distance (or range) between a first wireless entity and a second wireless entity. In an aspect, the first wireless entity transmits a first positioning reference signaling (PRS) signal to the second wireless entity at a first time, where the first PRS signal is received by the second wireless entity at a second time, and receives a second PRS signal from the second wireless entity at a third time, where the second PRS signal is transmitted by the second wireless entity at a fourth time. The first wireless entity enables the distance to be determined by a location computing entity, for example, by a location server, based on the first, second, third, and fourth times. The first wireless entity may be a mobile device or a base station and the second wireless entity may be the other of the mobile device or base station.

Abstract: Methods and apparatuses are presented for obfuscating the locations of terrestrial wireless transceivers, including wireless access points and femtocells. According to some embodiments, a method may receive, by a mobile device, data for a terrestrial wireless transceiver, wherein the data includes location coordinates of the terrestrial wireless transceiver, and wherein the location coordinates include an error term. Additionally, the method may include determining the error term based on the data. Furthermore, the method may include determining a corrected location of the terrestrial wireless transceiver by removing the error term from the location coordinates. In some instances, the data can further include a unique identifier associated with the terrestrial wireless transceiver, and wherein the error term is further determined based on the unique identifier.
