Abstract
Provided is an operation method of user equipment in communication with a satellite in a non-terrestrial network, the operation method including receiving a synchronization signal block (SSB) burst through wide beams from the satellite, performing, based on the SSB burst, an indexing operation on narrow beams corresponding to the wide beams, estimating an optimal narrow beam, based on the indexed narrow beams, and performing random access to the satellite, based on the estimated narrow beam.
Claims20
An operation method of user equipment in communication with a satellite in a non-terrestrial network, the operation method comprising:
- receiving a synchronization signal block (SSB) burst through wide beams from the satellite;
- performing, based on the SSB burst, an indexing operation on narrow beams corresponding to the wide beams;
- estimating an optimal narrow beam, based on the indexed narrow beams;
- and
- performing random access to the satellite, based on the estimated narrow beam.
An operation method of user equipment in communication with a satellite in a non-terrestrial network, the operation method comprising:
- receiving a synchronization signal block (SSB) burst through wide beams from the satellite;
- obtaining indexing assistance information included in the SSB burst;
- performing, based on the indexing assistance information, an indexing operation on narrow beams corresponding to the wide beams;
- selecting one of the indexed narrow beams;
- and
- performing random access to the satellite, based on the selected narrow beam.
User equipment comprising:
- a radio frequency (RF) circuit configured to receive a synchronization signal block (SSB) burst through wide beams from a satellite in a non-terrestrial network;
- and
- a processor configured to perform, based on the SSB burst, an indexing operation on narrow beams corresponding to the wide beams, estimate an optimal narrow beam, based on the indexed narrow beams, and perform random access to the satellite, based on the estimated narrow beam.
