System and method for multiple management of transmission resources of a space system for multi-cell radio communication

摘要

The system has a set of user terminals (10, 12, 14) receiving and transmitting service and signal messages from and to a transparent or bent-pipe communication satellite (6) i.e. relay, on a bidirectional wireless way (44), which consists of an outbound downlink (48) and an inbound uplink (46). The satellite transmits and receives the received and transmitted service and signal messages on the downlink and on the uplink. Control units (100, 102, 104) manage frequency and spatial resources of associated virtual cells (70, 72, 74), and pass the messages to the virtual cells. An independent claim is also included for a method for changing transmission resources within same virtual cell during communication of a terminal in a satellite cellular radio-communication system.
