Claim:
1. A method for handling inter-cell interference, comprising: obtaining downtilt coordination information of a local cell and obtaining downtilt coordination information of a neighbor cell; and setting a downtilt of a time-frequency resource block on an antenna of the local cell with respect to a to-be-coordinated user equipment based on the obtained downtilt coordination information of the local cell and the obtained downtilt coordination information of the neighbor cell, and wherein a useable range comprising a plurality of downtilts of the downtilt for the time-frequency resource block on the antenna of the local cell with respect to the to-be-coordinated user equipment within a service range of the local cell is determined according to the downtilt coordination information of the local cell and the downtilt coordination information of the neighbor cell which comprises any one or more of the following: optimal downtilt information of time-frequency resource blocks on an antenna of a cell with respect to user equipments within a service range of the cell, location information of user equipments within the service range of the cell, location information of a base station of the cell, use probabilities of downtilts on each time-frequency resource block on the antenna of the cell, probabilities that each time-frequency resource block on the base station of the cell is assigned to different user equipments, and downtilts not recommended for time-frequency resource blocks on an antenna of a neighboring cell.
