Abstract: Devices, methods and computer programs for timing advance variation compensation in wireless communications are disclosed Timing advance variation for a client device communicating with a network node device at least partially via an air/space born vehicle communication connection is determined based on measurements on uplink signaling from the client device. A timing advance compensation function curve from a set of predetermined timing advance compensation function curves is selected, such that the selected timing advance compensation function curve corresponds with the determined timing advance variation. An indication of the selected timing advance compensation function curve is signaled to the client device.

Abstract: According to an aspect, there is provided a controller of a pool of terminal devices comprising means for performing the following. Initially, information on requirements of data traffic to be handled by the pool of terminal devices and data traffic statistics for the pool are maintained in a memory of the controller. Upon receiving results of scanning of available radio access networks and capabilities from one or more primary terminal devices, the controller analyzes the results of the scanning, the requirements of the data traffic and the data traffic statistics to determine optimal radio access configurations for the pool of terminal devices for satisfying the requirements of the data traffic. Then, the controller configures the pool of terminal devices for providing radio access according to the optimal radio access configurations. Finally, the controller provides radio access using the pool of terminal devices according to the optimal radio access configurations.

Abstract: A serving network node may be configured to determine an altitude position state of a terminal device. The altitude position state may be determined using information in a plurality of reports received from the terminal device, the reports comprising at least one indication of signal reception quality (201). For example, the altitude position state may be determined by comparing the at least one indication of the signal reception quality of the plurality of reports to a comparison model, or by comparing cells in the plurality of reports to information of cells in a certain area (202). Further, more reports may be requested from the terminal device for improved certainty of the determining, if needed. The determined altitude position state of the terminal device may further be transmitted, as a part of a handover process, to a handover target network node (203).
