Abstract
The present disclosure relates to a 5G or 6G communication system for supporting data transmission rates higher than that of a 4G communication system such as LTE. More particularly, the present disclosure relates to a method and apparatus in which a base station transmits a synchronization signal via a satellite and a terminal detects the synchronization signal in a communication system.
Claims15
A method performed by a terminal supporting non-terrestrial network (NTN) communication in a wireless communication system, the method comprising:
- identifying a synchronization raster to perform initial access for NTN communication;
- and
- receiving a synchronization signal block (SSB) from a satellite based on the identified synchronization raster,
- wherein a position of the synchronization raster is identified by a global synchronization channel number (GSCN),
- wherein each GSCN is determined based on a first parameter related to an order of clusters formed by at least one synchronization raster and a second parameter related to an order of synchronization rasters included in a cluster.
A terminal supporting non-terrestrial network (NTN) communication in a wireless communication system, comprising:
- a transceiver to transmit and receive signals;
- and
- a controller connected to the transceiver,
- wherein the controller is configured to:
- identify a synchronization raster to perform initial access for NTN communication, and
- receive a synchronization signal block (SSB) from a satellite based on the identified synchronization raster,
- wherein a position of the synchronization raster is identified by a global synchronization channel number (GSCN),
- wherein each GSCN is determined based on a first parameter related to an order of clusters formed by at least one synchronization raster and a second parameter related to an order of synchronization rasters included in a cluster.
