Methods for radio resource management in moving networks

A wireless transmit/receive unit (WTRU) configured to communicate in a non-terrestrial network (NTN) comprising a plurality of satellites, the WTRU comprising:

• a transceiver and a processor, wherein the transceiver and the processor are configured to:
• receive, from a network node, indications of a plurality of measurement configurations and a corresponding plurality of activation/deactivation criteria associated with the plurality of satellites, wherein the activation/deactivation criteria includes at least activation timing information;
• and
• perform measurements on satellite cell beams for satellites with active measurement configurations during corresponding active time ranges in accordance with the activation/deactivation criteria, and report results based on the measurements to NTN.
