Abstract: A 5G communication system between at least one mobile terminal and a core network, the communication system includes at least one satellite, an access network comprising a plurality of base stations and a gateway disposed between the satellite and one of the base stations, the satellite and the gateway being able to exchange service frames comprising uplink service frames and downlink service frames, the uplink service frames having to be temporally aligned with the downlink service frames around a time reference point.

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 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.
