Abstract: Example embodiments provide signaling between a network node and a client node in non-terrestrial network which enables optimizing energy consumption of the client node. The client node may adapt its power saving mode duration to end at a suitable time for transmission based on information about transmission opportunities computed by the network node. The network nodes may be moving network nodes that operate at altitude, such as satellites. Apparatuses, methods, and computer programs are disclosed.

Abstract: According to an example embodiment, a network node device is configured to when the network node device is connected to a first satellite of a non-terrestrial network, identify at least one client device needing to be served by the network node device, wherein the at least one client device is currently served by a second network node device via a first cell provided by a second satellite of the non-terrestrial network; in response to identifying that the at least one client device needs to be served by the network node device, provide a second cell to at least one the client device via the second satellite; and after the at least one client device has performed a handover from the first cell to the second cell, switch the second cell to be provided by the first satellite.

Abstract: Various example embodiments relate to a solution for non-terrestrial network communication. A user device for non-terrestrial network communication may be configured to determine that a connection to a non-terrestrial network having a discontinuous coverage is unavailable, the non-terrestrial network providing at least one cell serving the user device; obtain data relating to cell availability of the at least one cell; determine a backoff time associated with a subsequent non-terrestrial network search based at least partly on the data relating to cell availability; and initiate a cell search of the non-terrestrial network again after expiration of the backoff time.

Abstract: A method, apparatus and computer program product are provided for cell change assistance in a non-terrestrial network. NTN, with a plurality of moving cells served by at least one satellite. A network element of the NTN provides cell change assistance information to a user equipment, UE, for selecting at least one moving cell of the plurality of moving cells. The UE receives cell change assistance information for selecting a cell for cell change. The cell change assistance information identifies at least a subset of the plurality of moving cells and us indicative of a geometric layout of at least the subset of the plurality of moving cells. The UE selects at least one moving cell from the plurality of moving cells as target cell for cell change, based on the received cell change assistance information

Abstract: An apparatus, method and computer program is described comprising: determining a set of candidate radio resources for transmitting data from a first communication node of a non-terrestrial network to a second communication node of the non-terrestrial network over a direct radio link; identifying one or more of the candidate radio resources as conflicting radio resources that conflict with at least one scheduled radio transmission in the non-terrestrial network based, at least in part, on a propagation delay associated with the at least one scheduled radio transmission and/or a propagation delay associated with the radio transmission by the first communication node; generating a subset of candidate radio resources by excluding the identified one or more conflicting radio resources from the set of candidate radio resources; and selecting a radio resource from the subset of candidate radio resources for transmitting the data over the direct radio link.
