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: Access, mobility management and regulatory services are supported for satellite access to a 5G core network. A coverage area, e.g., a country or region, is divided into fixed virtual cells and fixed tracking areas. The UE receives configuration information for fixed cells and fixed tracking areas associated with a serving PLMN. The fixed cells and the fixed tracking areas are defined, independently of each other, as fixed geographic areas. A position of the UE is used to determine a fixed serving cell and/or fixed tracking area for the UE. A service operation for the UE is enabled for the serving PLMN based on the fixed serving cell or the fixed tracking area. A fixed cell may be associated with an overlapping fixed tracking area by assigning a color code to the tracking area and appending the color code to an ID for the fixed cell.

Abstract: A wireless network including user equipment (UE) and base stations is configured to perform position determination with low latency and high availability within the Time-Sensitive Networking (TSN) framework. For example, the UE may be integrated as a sensor in a motion control system or similar applications. The UE and base stations are synchronized with the TSN clock, and are configured to perform positioning measurements at a specific time point within the TSN framework. The time point, for example, may be a global sampling point, at which all sensor nodes in the TSN framework perform position measurements. A location server may be provided with the positioning measurements or a position estimate from the UE and provide the position estimate to an external client, such as a motion controller in a motion control system.

Abstract: The described techniques provide for a wireless base station to receive emergency instructions for aerial UEs from a third party system. The base station may generate a broadcast message including the emergency instructions, associated parameters, and an indication that the broadcast message is for aerial UEs. The base station may transmit a short message indicating aerial UEs to monitor for the broadcast message and may transmit the broadcast message accordingly. An aerial UE may receive the short message and the broadcast message and, based on the indication that the broadcast message is for aerial UEs, may decode emergency information of the broadcast message to obtain the emergency instructions and associated parameters. The aerial UE may perform one or more actions based on the decoded emergency instructions.

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, for a server, that includes a first information element and a second information element, wherein the first information element includes at least one field that is common to multiple positioning methods and wherein the at least one field comprises 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, wherein the second information element includes at least one field that is specific to a first positioning method, and performing positioning in response to the Request Location Information message.

Abstract: Access, mobility management and regulatory services are supported for satellite access to a Fifth Generation (5G) core network (5GCN). A location of a UE may be obtained by a UE or by a base station and used to determine a country in which the UE is located. The UE can then select a serving PLMN in the country of the UE which is accessible from a radio cell supported by a satellite. The UE can register with the serving PLMN and receive information from the serving PLMN concerning fixed cells and fixed tracking areas supported by the serving PLMN. If the UE attempt to register with a PLMN not in the country of the UE, a serving base station can reject the attempt and indicate the country to the UE.

Abstract: Access, mobility management and regulatory services are supported for satellite access to a 5G core network. Radio cells supported by a satellite may be moving as the satellite moves and may undergo changes, e.g. when a satellite is transferred from one earth station to another. A base station may broadcast a remaining lifetime for a radio cell (e.g. in a system information block) which indicates to UEs how much longer the radio cell can be accessed before a change occurs. A radio cell may also indicate support for one or more fixed tracking areas (TAs) in coverage of the radio cell. A base station may broadcast a remaining lifetime for each TA to indicate to UEs how much longer a TA will be supported by the radio cell. UEs can use the indications to perform cell change or handover to other radio cells and/or other satellites.

Abstract: Methods and techniques are described for supporting location services for a user equipment (UE) in a Fifth Generation wireless network in which a base station, such as a gNB or ng-eNB, broadcasts a Positioning Reference Signal (PRS) in a plurality of different directions and at a plurality of different times. A PRS muting configuration is used in which PRS is muted using a time based and angle based pattern to prevent interference between beams transmitted by other base stations and/or to prevent interference between beams transmitted simultaneously by a single base station. The time based and angle based muting pattern, for example, may provide an indication for each direction in the plurality of different directions and for each time in the plurality of different times and as to whether the PRS is transmitted or muted by the base station.

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.
