The embodiment of the invention discloses a method and a device for avoiding inter-cell interference and relates to the technical field of wireless communication. The inter-cell interference can be effectively avoided by low signaling interaction. The method comprises the following steps of: dividing users of a cell into safety users and collision users, wherein the safety users do not interfere with a neighbor cell or interfere with the neighbor cell in a preset range during downlink transmission of the users or when the users perform uplink transmission, and the collision users interfere with the neighbor cell out of the preset range during downlink transmission of the users or when the users perform uplink transmission; and assigning the collision users of the cell and the neighbor cell to different time frequency resources in a data transmission sub-frame. The invention is mainly applicable to avoiding of the inter-cell interference in cellular mobile communication systems.
