Abstract: Techniques are described for supporting satellite wireless access for a user equipment (UE) using fixed tracking areas (TAs). TA identities (TAIs) are broadcast in a satellite radio cell by a base station indicating which TAs are covered by the radio cell. A UE can access a radio cell if at least one broadcast TAI is not forbidden for the UE. A base station provides the TAIs broadcast in a radio cell and a TAI for a TA in which a UE is located to a core network node to support access by the UE. The core network node uses the broadcast TAIs to decide whether UE access is allowed and uses the broadcast TAIs and the TAI to assign a UE registration area. The UE may transfer all the broadcast TAIs to a forbidden TAI list if UE access is rejected by the core network node.

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: During a positioning session, a wake up signal (WUS) configuration for a user equipment (UE) operating in a discontinuous reception (DRX) mode may be adapted to avoid dormant secondary serving cells (SCells) for positioning. The location server, for example, may configure positioning assistance data and scheduling of uplink sounding reference signals (SRS) to exclude SCells that are included in a dormancy list for the UE. The location server, alternatively, may provide to a serving base station supporting a primary serving cell (PCell) for the UE an indication of the SCells to be used for positioning. The SCells may be removed from the dormancy list during the positioning session or may be brought out of dormancy for all or selected monitoring occasions during the positioning session.

Abstract: A mobile device is disclosed. The mobile device may receive one or more wireless local area network (WLAN) signals. The mobile device may determine Channel State Information (CSI) data from the one or more WLAN signals. The mobile device may determine one or more environmental characteristics associated with an environment of the mobile device based on the CSI data. The mobile device may send information indicative of the one or more environmental characteristics to a location server (LS), or determine a position of the mobile device based at least in part on the one or more environmental characteristics, or any combination thereof.

Abstract: Techniques are discussed herein for providing on-demand positioning reference signals (PRS) to user equipment (UE). An example method for determining a location of a user equipment according to the disclosure includes receiving a first assistance data associated with a first positioning reference signal configuration, transmitting a request to modify one or more parameters of the first positioning reference signal configuration, receiving a second assistance data associated with a second positioning reference signal configuration, wherein the second positioning reference signal configuration is based at least in part on the request to modify the one or more parameters of the first positioning reference signal configuration, obtaining measurements from one or more positioning reference signals based at least in part on the second assistance data, and determining the location based at least on part on measurements obtained from the one or more positioning reference signals.

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: 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: Location services for a user equipment (UE) are supported with a Network Exposure Function (NEF) serving as a focal point for any location request. An entity that needs the location of the UE sends a location request to the NEF in the home PLMN or Visited PLMN for the UE. The location request includes, e.g., a type of location request, a required location accuracy, a required response time or some combination of these. The NEF determines whether to use a Gateway Mobile Location Center (GMLC) or a serving Access and Mobility Management Function (AMF) for the UE to obtain the UE location based on the content of the location request and sends the location request to the GMLC or serving AMF accordingly. Additionally, if the serving AMF is used, a serving base station may obtain the UE location and send the UE location to the serving AMF.

Abstract: Techniques are described to support call routing and location for a user equipment (UE) with satellite wireless access to a serving PLMN. The UE sends a Session Initiation Protocol (SIP) INVITE message to a network node, such as a P-CSCF, that includes an indication of satellite access for the UE. In response the network node sends a request to another network node for a cell ID for a fixed cell in which the UE is located. The fixed cell can be independent of satellite radio cells for the serving PLMN. The network node may receive the cell ID for the fixed cell and sends the SIP INVITE message to another network node (e.g., an E-CSCF or LRF) with the cell ID for the fixed cell. The other network node may use the cell ID to route the SIP INVITE message or obtain an approximate location of the UE.

Abstract: Methods and systems for wireless communication are provided. In one example, a mobile device is configured to: obtain beam support information of a plurality of cells; perform measurements of one or more signals at the mobile device based on the beam support information of the plurality of cells to support a location determination operation for the mobile device; and transmit results of the measurements of the one or more signals to at least one of a location server or to a base station to support the location determination operation. The beam support information may include: a number of beams supported at each cell of the plurality of cells, information to identify each beam of the number of beams supported at the each cell, beam width information of the each beam, and/or Positioning reference Signals (PRS) codebook information which encapsulates the beams which are enabled along various elevation and azimuth angles.
