In one exemplary embodiment, a mobile device may comprise: a communication interface configured to monitor signals from a plurality of satellites, a processor configured to determine impairment of one or more satellites in the plurality of satellites using the signals form the plurality of satellites, a memory configured to store a status of the determined impairment of one or more satellites in the plurality of satellites, and the communication interface that transmits the status of the determined impairment of the one or more satellites in the plurality of satellites to a server. The processor further determines a position of the mobile device using the status of the determined impairment of one or more satellites in the plurality of satellites, and stores the determined position and a corresponding digital certificate indicative of authenticity of the determined position in a memory.

Disclosed are techniques for wireless positioning. In an aspect, a user equipment (UE) performs at least one positioning procedure with at least one transmission-reception point (TRP), and transmits a positioning report for the at least one positioning procedure via first low layer signaling or both the first low layer signaling and second signaling different than the first low layer signaling.

The present disclosure relates to a communication method and system for converging a 5.sup.th-Generation (5G) communication system for supporting higher data rates beyond a 4.sup.th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. The disclosure relates to a method for positioning, which includes sending a positioning information request by a first entity to one or more second entities, receiving positioning information response by the first entity. In addition, the disclosure further relates to a method for positioning, which includes sending a request message related to positioning by a first entity to a second entity, and receiving a response message from a second entity by the first entity.

In one example, a processing system including at least one processor may receive a first set of location reports for a device in an environment including a plurality of wireless beacons, determine, based on the first set of location reports for the device, a first location of the device in the environment, initiate, based on the first location of the device in the environment, a sending of a content item toward the device, receive a second set of location reports for the device, determine, based on the second set of location reports for the device, a second location of the device in the environment, and provide, based on the first location of the device in the environment and the second location of the device in the environment, a metric indicative of an effectiveness of the content item in causing movement of a user of the device in the environment.

Improved systems, apparatus, and methods for enhanced positioning of an airborne relocatable communication hub supporting wireless devices are described. Such a method begins with moving an aerial communication drone operating as the airborne relocatable communication hub to a first deployed airborne position, detecting a first signal broadcast by a first wireless device using a communication hub interface on the drone, and detecting a second signal broadcast by a second wireless device using the communication hub interface. The method has the drone comparing a first connection signal strength for the first signal and a second connection signal strength for the second signal, and repositioning the aerial communication drone to a second deployed airborne position based upon the comparison. Once repositioned at the second deployed airborne position, the method has the drone linking the first and second wireless devices using the communication hub interface on the aerial communication drone.

In an aspect, a communications node (e.g., TRP or UE) obtains (e.g., measures) timing group delays associated with different positioning procedures to determine time drift information, and reports the time drift information to an external entity for position estimation.

A processing system including at least one processor may obtain a location of a mobile device and a barometric pressure reading of the mobile device, identify a weather reference area and a ground reference area containing the location, and calculate an elevation of the mobile device from the barometric pressure reading of the mobile device and a barometric pressure metric of a weather reference point of the weather reference area, where the weather reference point has a predetermined elevation. The processing system may then determine a height of the mobile device over a ground level of the location based upon the elevation of the mobile device that is calculated and based upon an elevation of a ground reference area containing the location and provide a report of the location of mobile device including the height of the mobile device over the ground level that is determined.

This invention provides a method, and a network node for implementing said method, of operating a network node to control a first Unmanned Aerial Vehicle, UAV, in a wireless telecommunications network, the method comprising: determining a collision risk for the first UAV; determining a reporting rate for the first UAV based on the collision risk; and sending a reporting rate update message to the first UAV so as to cause the first UAV to report its position at the determined reporting rate. This invention also provides a method, and an Unmanned Aerial Vehicle for implementing said method, of operating an Unmanned Aerial Vehicle, UAV, in a wireless telecommunications network, the method comprising the steps of: receiving a reporting rate update message from a network node in the wireless telecommunications network, the reporting rate update message including a reporting rate; determining position of the UAV; and sending a position report message to the network node at the reporting rate, the position report message including the determined position.

Group common Downlink Control Information (DCI) for Aperiodic Positioning Reference Signal (AP-PRS) triggering is described herein. Embodiments for such AP-PRS may include AP-PRS triggering commands and/or positioning measurement request commands, and may be mapped to one or more bits of different blocks of the group common DCI to identify different aspects of the AP-PRS, such as one or more Positioning Frequency Layers (PFLs), PRS identifiers (PRS-IDs), PRS resource sets, and/or PRS resources.

During a positioning session in which multiple location reports are provided, a user equipment (UE) that has little or no movement may provide an indication to an entity in the wireless network that there is no update for one or more location measurements. The UE may provide the indication to a serving base station in a Physical layer waveform. The base station may bypass the location server and provide an indication to an external client that the UE position has not changed. The UE may provide the indication to a location server in a location information report or by not sending a location information report by an expiration time. The indication of no update may be provided by a bit that indicates no location measurements are updated or that a particular location measurement is not updated.
