SATELLITE, MOBILE TERMINAL, AND COMPLEMENTARY TERRESTRIAL COMPONENT IN OFDM BASED MULTI-BEAM SATELLITE SYSTEM REUSING THE SAME FREQUENCY BAND FOR ALL THE BEAMS, AND COMMUNICATION METHOD THEREOF |
摘要 |
Provided is a communication method of a mobile terminal in an orthogonal frequency division multiplexing (OFDM) based multi-beam satellite system reusing the same frequency band for all the beams, the method including: receiving location information of the mobile terminal from a satellite to determine a location of the mobile terminal within multiple beams; determining a subcarrier group for a communication with the satellite according to the location of the mobile terminal within the multiple beams; and communicating with the satellite using the subcarrier group for the communication with the satellite.
