A method performed by a wireless device includes receiving ephemeris data from a network node associated with a first cell. The ephemeris data is associated with a satellite serving a second cell, and the ephemeris data is coarse ephemeris data comprising less than full accuracy than full ephemeris data. The wireless device uses the coarse ephemeris data to locate a beam associated with the second cell and synchronizes with the second cell.

Configuration of measurement requirements on cells and beams in NR is made more efficient by, in a user equipment, UE, receiving, information from a network node, which information indicates: a first number K of beams to be measured by the UE, and a second number L of cells in which the UE is required to measure the first number K of beams. The UE then carries out measurements using the received information; and performs at least one operational task based on a result of the measurements.

According to some embodiments, a method of operating a network node is provided. A first information element IE is provided including an indication of an added synchronization signal block/physical cell identity SSB/PCI. The indication of the added SSB/PCI indicates an SSB and associated PCI that are associated with a radio link. A second IE is provided including the indication of the added SSB/PCI.
