Definitions

  • the present invention relates to a system for realizing a level-2 cell change for non-terrestrial networks, according to the threshold values determined for the signal level and quality of the cell being served.
  • NTN Non-Terrestrial Networks
  • a method for wireless communication includes initiating, by a user equipment (UE), a registration process with a network entity of an NTN to access the NTN. The method also includes transmitting, by the UE to the network entity, UE capability information of the UE.
  • UE user equipment
  • the method further includes receiving, by the UE from the network entity, a handover command; this handover command comprises a handover time indicator associated with a target handover time for the UE to perform a handover operation from a first beam to a second beam.
  • a handover command comprises a handover time indicator associated with a target handover time for the UE to perform a handover operation from a first beam to a second beam.
  • a terminal added to the nonterrestrial network measures the signal quality.
  • the system prioritizes MAC (level 2) cell changes and performs RRC (level 3) cell changes, when necessary.
  • An objective of the present invention is to realize a system which is developed for realizing a level-2 cell change for non-terrestrial networks, according to the threshold values determined for the signal level and quality of the cell being served.
  • Another objective of the present invention is to realize a system which is developed for realizing a novel intercellular L2 (level 2) change at non-terrestrial networks with prioritized latency, signaling load and energy consumption
  • Another objective of the present invention is to realize a system which is developed for measuring signal quality and level from a user device.
  • Another objective of the present invention is to realize a system which is developed for preventing significant protocol changes on both the network and user terminal part via implementation of the cell change algorithm given in 3 GPP standards with minimum changes.
