1. A method for selecting, by a multi-antenna base station of a wireless communications system, at least one transmission beam to transmit data to at least one terminal, the method comprising:
determining a grid of N2 transmission beams intended to cover a portion of the space served by the base station and generated by using N1 antennas of the base station, where N1 and N2 designating integers such that N2>N1, and
selecting one or more non-adjacent beams of the grid to transmit data to at least one terminal during at least one given time interval.
