Method and device for use in non-terrestrial network (ntn)

A User Equipment (UE) comprising:

• a processor;
• a receiver;
• and
• a transmitter;
• the receiver configured to perform a measurement on a first radio signal, wherein the first radio signal is associated with a neighboring cell of a neighbor node;
• the processor configured to determine a measurement value based on the measurement performed on the first radio signal;
• the processor further configured to determine a reference value based on the signaling;
• the processor further configured to determine whether the measurement value is greater than the reference value;
• the processor further configured to determine, based on a distance threshold, whether a relative positional relationship between a geographical location of the UE and a reference geographical area is fulfilled;
• and
• the transmitter configured to, on a condition that the measurement value is greater than the reference value, and the relative positional relationship between the geographical location of the UE and the reference geographical area is fulfilled, transmit a second radio signal.
