Claim 4:
5. The method of space communication as claimed in claim 4, wherein
the control data relate to an implementation:
of a mechanism of contention access control on the random uplink UL data channel, including congestion control and stream control and taking into account parameters of a satellite-based or HAPS station-based communication channel, with selection of timeouts and selection of a mode of transmission as a function of the type of data to be transmitted; and/or
of a specific power control mechanism suited to the uplink UL data channel; and/or
of a Doppler drifts control mechanism; and/or
of an economizer mechanism for saving electrical energy of the at least one user terminal based on the provision of a temporal duty cycle information item representative of a temporal sharing of one and the same downlink DL data channel carrier frequency by several logical beams served by one and the same satellite.
