An allocation method for allocating time-frequency telecommunication resources in a wireless satellite telecommunication system, said satellite telecommunication system comprising a satellite, user terminals UE (20_1, 20_2), the satellite being suitable for simultaneously implementing multiple telecommunication beams (B_1, B_2) that are each associated, at a given time, with a separate user terminal UE (20_1, 20_2) and for dynamically re-centring each beam on the UE associated with said beam; each telecommunication beam (B_1, B_2) being established according to time-frequency resources selectively allocated to the associated UE (20_1, 20_2); said method comprising the following steps implemented by an electronic resource allocation unit: - obtaining the position of each UE (20_1, 20_2); and being characterised in that: - given a set of grids (G1, G2) each representing at least a portion of the Earth's surface and each containing a plurality of non-contiguous areas distributed in the grid, the distance between any two areas of a grid being above a determined non-zero threshold associated with the grid, the allocation of the time-frequency resources relative to a time T is performed by applying at least the following rule, at least one and the same time-frequency resource being associated with the grid beforehand: said time-frequency resource associated with the grid may be allocated to each of 2 UEs (20_1, 20_2) only if the obtained positions of said 2 UEs are in separate areas from said plurality of non-contiguous areas distributed in the grid. said satellite telecommunication system comprising a satellite, user terminals UE (20_1, 20_2), the satellite being suitable for simultaneously implementing multiple telecommunication beams (B_1, B_2) that are each associated, at a given time, with a separate user terminal UE (20_1, 20_2) and for dynamically re-centring each beam on the UE associated with said beam; each telecommunication beam (B_1, B_2) being established according to time-frequency resources selectively allocated to the associated UE (20_1, 20_2); said method comprising the following steps implemented by an electronic resource allocation unit: - obtaining the position of each UE (20_1, 20_2); and being characterised in that: - given a set of grids (G1, G2) each representing at least a portion of the Earth's surface and each containing a plurality of non-contiguous areas distributed in the grid, the distance between any two areas of a grid being above a determined non-zero threshold associated with the grid, the allocation of the time-frequency resources relative to a time T is performed by applying at least the following rule, at least one and the same time-frequency resource being associated with the grid beforehand: said time-frequency resource associated with the grid may be allocated to each of 2 UEs (20_1, 20_2) only if the obtained positions of said 2 UEs are in separate areas from said plurality of non-contiguous areas distributed in the grid. - obtaining the position of each UE (20_1, 20_2); and being characterised in that: - given a set of grids (G1, G2) each representing at least a portion of the Earth's surface and each containing a plurality of non-contiguous areas distributed in the grid, the distance between any two areas of a grid being above a determined non-zero threshold associated with the grid, the allocation of the time-frequency resources relative to a time T is performed by applying at least the following rule, at least one and the same time-frequency resource being associated with the grid beforehand: said time-frequency resource associated with the grid may be allocated to each of 2 UEs (20_1, 20_2) only if the obtained positions of said 2 UEs are in separate areas from said plurality of non-contiguous areas distributed in the grid.
