The invention refers to a method for dynamically setting the radiation pattern of an antenna of a base station connected to User Equipments in a cellular telecommunications network by obtaining data of the positions of User Equipments located under coverage of the base station during a predetermined period of time; statistically treating said data of the positions of User Equipments to obtain at least one statistical parameter of said data, and changing the radiation pattern of the antenna depending on the result of comparing said at least one statistical parameter with a pre-established value.
