Patent ID: 7555266

Claim:
A method for data transmission in a radio communication system having at least two base stations and radio stations that are connected in each case to one of the base stations via wireless interfaces, at least a first base station having an antenna arrangement with a plurality of antenna elements and a signal processing device for transmitting and receiving data as a function of direction, comprising: transmitting data from the first base station to a first radio station communicating therewith in a cell, concurrently with transmission of data from a second base station adjacent to the first base station, to at least one second radio station communicating therewith in an adjacent cell which is adjacent to the cell; determining, at the first base station, whether downlink transmission of the data from the first base station causes a disturbance for the at least one second radio station in the adjacent cell; and reducing downlink transmission power of the antenna arrangement of the first base station only in a downlink direction that is directed towards the at least one second radio station in the adjacent cell when it is determined that downlink transmission of the data from the first base station does cause a disturbance for the at least one second radio station in the adjacent cell.
