1. An apparatus for wireless communication at a user equipment (UE), comprising:
a processor; and
memory coupled with the processor, the processor and memory configured to:
receive, from a satellite at a first time period, a first control message comprising a configuration of a target cell to use at a second time period for performing a handover procedure from a source cell to the target cell, the second time period occurring after the first time period;
store the configuration of the target cell included in the first control message;
receive, from the satellite, a second control message at the second time period based at least in part on storing the configuration included in the first control message, the second control message triggering the UE to use the configuration included in the first control message to perform the handover procedure from the source cell to the target cell, the second control message being different from the first control message, wherein the second control message indicates that a context of the UE is relocated to the target cell, and wherein the UE is configured to store the configuration for a duration at least from receiving the first control message until receiving the second control message; and
perform the handover procedure from the source cell to the target cell using the configuration of the target cell included in the first control message in response to receiving the second control message.
