Abstract: A method is provided for compensating time differences for the time alignment of uplink service frames and downlink service frames, the uplink service frames and the downlink service frames being exchanged between a satellite and a mobile terminal. The mobile terminal belonging to a 5G cell comprising a cell centre, the pre-compensation is calculated on the basis of a main beam directed towards the centre (O) of the cell (5G).

Abstract: A ground station with P antennas for individually tracking a satellite out of an origin first moving satellite S1 and a destination second moving satellite S2 comprises, connected in series, a multi-channel reception and processing device and a combination device with configurable diversity, and comprises a device for managing diversity and seamless handover of a reception communication link from the origin first satellite S1 to the destination second satellite S2. The diversity and seamless handover management device is configured to manage and coordinate the execution of a succession of k seamless and unitary antenna handovers Bi, and during each seamless and unitary handover Bi, control the antennas, the multi-channel reception and processing device and the combination device with configurable diversity by determining and sending to them respectively: satellite acquisition pointing commands, and commands for alignment in time and in phase of the P signals received as input of the multi-channel reception and processing device generated as a function of measurements of time and phase deviations of P-1 signals received as input in relation to the signal received as input taken as reference signal, and a setpoint for selection of the output processed signals to be combined as a function of the scheduling of the handover from the first diversity configuration C1 to the second diversity configuration C2 and as a function of measurements of qualities of the signals received as input of the reception and processing device.

Abstract: A method for allocating time-frequency telecommunication resources in a telecommunication system includes a satellite, user terminals UE (20_1, 20_2), the satellite simultaneously rendering multiple telecommunication beams (B_1, B_2) that are each associated with a separate user terminal UE (20_1, 20_2) and dynamically re-centering each beam on the associated UE; the method comprising: given a set of grids each representing at least a portion of the Earth's surface and each comprising a plurality of areas, the distance between any two areas of a grid being above a determined non-zero threshold associated with the grid, the time-frequency resources are allocated relative to a time T by applying at least the following rule: a time-frequency resource associated with the grid may be allocated to each of 2 UEs (20_1, 20_2) only if the positions of the 2 UEs are in separate areas of the grid.

Abstract: A method comprises a preprocessing step consisting, in the gateway station, in pre-segmenting the data as a function of the carrier frequency which is dedicated to them on the downlink DL, in reassembling and in encapsulating the pre-segmented data in successive basic frames DL BB-Frames, that can be transmitted over the downlink, each basic frame DL BB-Frame of the downlink being encapsulated by addition of a specific transport header DL BB-TH on the downlink and a data field, and a step consisting, in the gateway station, in incorporating the different basic frames DL BB-Frames of the downlink in the data field of the different basic frames UL BB-Frames of the uplink.
