摘要： Disclosed are techniques for sidelink positioning. In an aspect, an initiator user equipment (UE) transmits a first request to create a sidelink positioning protocol (SLPP) session to each recipient UE among a set of one or more recipient UEs, and receives first responses from the set of one or more recipient UEs that each indicate an acceptance or rejection of the SLPP session by the recipient. A group of one or more UEs for participation in the SLPP session is determined by the initiator UE from among recipient UEs from which a respective first response that indicates the acceptance of the SLPP session is received. In another aspect, a UE transmitting an SLPP message may indicate a first casting mode (e.g., unicast, groupcast, broadcast, etc.) of the SLPP message and may optionally indicate a second casting mode (e.g., unicast, groupcast, broadcast, etc.) for response(s) to the SLPP message.

摘要： Satellite access to a PLMN with a Fifth Generation (5G) core network (5GCN) is supported by a serving satellite NodeB (gNB). The gNB determines or verifies the country in which a user equipment (UE) is located to ensure that the UE is located in the same country as the PLMN. The gNB may determine the country of the UE based on UE measurements from broadcast satellite signals and a positioning ID (PID) broadcast for each radio cell. The PID frequently changes to prevent spoofing. The gNB may use multiple UE measurements from a moving radio cell over a period of time to generate a more accurate location for the UE. The gNB may indicate to a 5GCN whether the country of the UE has been verified. The 5GCN will determine the location and country of the UE if the gNB indicates that the country is not fully verified.

摘要： Techniques for verifying a user equipment (UE) location in a non-terrestrial network (NTN) are disclosed. In some embodiments, such techniques may involve receiving location data of the target UE; obtaining one or more locations of one or more other UEs that are within a sidelink communication range of the target UE; receiving sidelink measurements obtained by the one or more other UEs relative to the target UE or by the target UE obtained for the one or more other UEs; and verifying the location data of the target UE (e.g., a location of the target UE) based at least on the sidelink measurements and the one or more locations of the one or more other UEs. The location verification may ensure that the target UE only accesses an NTN that is allowed to serve the location of the target UE.

摘要： Methods and techniques are described for enhancing positioning related protocols in order to indicate when one location session is different from another location session. One or more messages provided in a location session by a location server to a user equipment (UE) may include a session indication, such as a session identifier (ID), where a different session ID is provided for each location session. The session indication may be a new session indicator provided in an initial message in a location session or an end session indicator provided in a final message in a location session. An extra message may be sent by the location server indicating that the location session has ended. A correlation ID provided by a network entity to the location server may be included in messages as the session indication, e.g., where a different correlation ID is provided for each location session.

摘要： 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.

摘要： 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.

摘要： Techniques are provided for obtaining environmental information using radio frequency sensing by one or more wireless devices. An example method of crowd sensing and/or environmental detection using radio frequency sensing with one or more wireless devices includes providing radio frequency sensing assistance data to one or more wireless devices, receiving radio frequency sensing reports from the one or more wireless devices, determining one or more environmental characteristics based on the radio frequency sensing reports. Environmental characteristics can include a location or movement of one or more target objects, or attributes of one or more target objects (e.g., one or many people, vehicles, animals, drones or other target objects), or any combinations thereof. This may assist with monitoring of a crowd or road traffic and/or with identifying and tracking a particular person or vehicle.

摘要： Techniques are provided for coordinating radio frequency (RF) sensing by a plurality of wireless devices. Wireless devices obtain RF sensing coordination information that includes orthogonality information for transmission and reception of RF sensing signals to reduce or eliminate interference between RF sensing by different devices. The orthogonality information may be provided by a server, another wireless device, or a group of wireless devices. The orthogonality information is used by a wireless device to transmit and receive RF sensing signals that are orthogonal to RF sensing signals transmitted and received by other nearby wireless devices. The orthogonality information may be for orthogonality in a spatial domain, time domain, frequency domain, code domain, or some combination of these. The wireless devices perform RF sensing operations based at least in part on the RF sensing coordination information and report the RF sensing results.

摘要： Certain aspects of the present disclosure provide a method of wireless communication by a user equipment (UE). The method generally includes performing a mobility procedure to establish a connection in a target radio access technology (RAT) while maintaining a context established in a source RAT, wherein one of the source RAT or target RAT is a terrestrial network (TN) RAT and the other is a non-terrestrial network (NTN) RAT and sending a tracking area update (TAU) request after establishing the connection in the target RAT.

摘要： 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.
