DEVICE AND METHOD FOR MONITORING RADIO RESOURCES FOR SATELLITE COMMUNICATION SYSTEMS

摘要

The invention relates to a device for monitoring the radio resources (100) of a satellite communication system, said radio resources being used by user equipment (102) in order to transmit and receive digital data by means of radio links (103, 104), a radio link being associated with a current operating point used for data transmission, an operating point corresponding to a modulation and MCS coding scheme associated with a frequency bandwidth B, said links being implemented using at least one satellite (101) as a communications relay. The device includes means for storing a set of predetermined values of the carrier-to-noise ratio (C/N)req required to reach the various rate values D, said values corresponding to various operating points that can be selected for data transmission, for acquiring the values of the C/N ratio when receiving at maximum power, for deducing the acquired values of the C/N ratio corresponding to operating points other than the current operating point, and for selecting an optimum operating point by radio link such that C/N is greater than or equal to (C/N)req. The invention also relates to a method for monitoring the radio resources of a satellite communication system.
