摘要： A method and device for determining an antenna cooperation set, and a method and device for determining a base station cooperation set in the mobile communication field are provided. The method includes that a signal joint processing system obtains the channel quality between a mobile terminal and at least two base stations, determines the base stations, which are corresponding to the channel quality higher than the channel quality threshold, as the cooperation base station set of the mobile terminal.
