A method for anonymizing movement data of road users equipped with a position detection device involves collecting movement data in the form of individual time- and position-related data records and transmitting the collected movement data to a backend server. At least some data records are transmitted indirectly via at least one other vehicle, or the position or time reference in at least some data records is made noisy prior to the transmission.

Disclosed are a method and an apparatus for configuring relay communication information, and an electronic device, and pertains to the field of communication technologies.

A method for organizing a data transmission network relates to information technologies and is intended to create an information transmission network between two or more points at a distance. The technical result of the claimed solution is a simplification in structure and a reduction in build time and the cost of network usage. The method is built on a node indexing algorithm based on a minimum number of packet retransmissions from modem to node. The method allows the use of a plurality of optionally moveable modems in a network and the use of wired and wireless networks, does not require the presence of a powerful base station, does not require additional time for rebuilding a network when signal transmission conditions are changed or when the number of nodes in a network is changed, allows a network structure to be built and the built structure to be further optimized, and does not require the nodes to store information about the network environment, which substantially lowers the cost of the solution.

Disclosed are techniques for wireless communication that over come problems associated with conventional approaches including load balancing and handover efficiency issues. In one aspect a wireless communication technique takes into account the load of a donor gNB before a relay decides to reselect from one donor gNB to another. In another aspect, a wireless communication technique ensures that relays are handed over to base stations that will be able to serve the relay as the mobile relay continues to follow its expected path (e.g. streets or tracks).
