Abstract

A method by a wireless device includes determining whether one or more conditions for triggering measurement reporting have occurred and triggering the measurement reporting based on the occurrence of the one or more conditions. The one or more conditions for triggering the measurement reporting are based on at least one of: a timing advance value in a source cell; the wireless device being within a pre-determined distance of a satellite node serving the source cell and/or a candidate target cell of the wireless device; an expected time for the wireless device to be served in the source cell and/or in the candidate target cell; an elevation angle of the satellite node serving the source cell and/or the candidate target cell; a point in time configured by the network is reached; detection of an identifier associated with a specific cell.
