According to one or more of the embodiments herein, systems and techniques for satellite relaying for geolocation and mitigation of Global Navigation Satellite System (GNSS) denial are provided. In one embodiment, a method comprises: receiving, at a processing device from a communication satellite along a communication path, a message initiated by a transmitting device and indicating a transmission time, the communication path having a target device with an unknown distance to the communication satellite; determining a reception time upon receiving the message, (the processing device and the transmitting device have synchronized clocks); determining a time difference between the transmission time and the reception time; calculating a distance between the communication satellite and the target device based on a portion of the determined time difference associated with only traversal of a portion of the communication path between the communication satellite and the target device; and performing action(s) based on the distance.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a network node may transmit, and a user equipment (UE) may receive, signaling indicating one or more common timing offset parameters that are based at least in part on one or more delays between a satellite and a reference point in a non-terrestrial network (NTN). The UE may determine a transmit time for an uplink signal based at least in part on the one or more common timing offset parameters and a starting time associated with an uplink slot in which the uplink signal is to arrive at the reference point. The UE may transmit the uplink signal at the transmit time. Numerous other aspects are described.

A method for providing authenticated correction information, in particular orbit, clock and bias/offset correction information, to a mobile receiver in a GNS system, including: receiving raw data from satellites at a plurality of reference stations; forwarding the raw data received at the reference stations to a central computation unit, in particular to a single central computation unit, using a data stream, in particular a common data stream; determining the correction information at the computation unit based on the raw data received from the different reference stations and transmitting the correction information via at least one satellite to the receiver for reliably determining a position of the mobile receiver.

An apparatus for determining a position of a user device, UE, of a wireless communication network is described. The wireless communication network includes a radio access network, RAN, and a plurality of non-terrestrial network, NTN, components, like an airborne vehicle or a spaceborne vehicle, operating on a bent pipe principle for a transmission between the UE and the RAN. The wherein the apparatus is to receive (1) for bent pipe transmissions between the UE and the RAN via at least two different NTN components respective values indicative of a distance between the UE and the RAN, or (2) one or more Doppler values for each link between the UE and the at least two NTN components. The apparatus is to obtain positions of the at least two NTN components, and determine the position of the UE using the obtained positions of the at least two NTN components and the values or one or more Doppler values.

The invention provides a method and an architecture for deploying non-terrestrial cellular network base stations, so as to enable cellular network coverage in remote areas, where no fixed infrastructure is available. The proposed methods allow for efficient power management at the terminal devices that need to synchronize to the airborne or spaceborne cellular base stations. This is particularly important for IoT devices, which have inherently limited power are computing resources.

Systems and methods for enabling communications via tablature for an application are disclosed. A system may include at least one processor configured to generate a table containing cells for holding values and enable association of a communications rule with a specific cell of the table, wherein the communications rule includes a trigger that automatically activates when a specific value in the specific cell meets a criterion. The processor may trigger the communications rule when the specific value in the specific cell meets the criterion, and communicate, upon triggering of the communications rule, a message relating to the specific value in the specific cell meeting the criterion.

There is disclosed at least a method for receiving a road object observation associated with the road object for a first link. The first link is associated with at least one second link. A first heading data is determined for the received road object observation. A matched location is determined for the received road object observation on the at least one second link. A second heading data is determined for the received road object observation, based on the determined matched location.
