Abstract:
Embodiments include methods for radio link monitoring (RLM) by a user equipment (UE) in a combined terrestrial and satellite wireless communication network. Such methods include, during a discontinuity in a connection between a UE and a terrestrial network node (TNN), performing RLM of the connection based on a second configuration. Such methods also include, before and/or after the discontinuity, performing RLM of the connection based on a first configuration. The connection includes a first link between the UE and a satellite and a second link between the satellite and the TNN. The discontinuity includes a link switch in at least one of the first link and the second link. The RLM before, during, and after the discontinuity can include various first, second, and third operations, respectively. Embodiments also include complementary methods performed by a TNN, as well as UEs and TNNs configured to perform operations corresponding to such methods.
