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. Because the channel quality between the mobile terminal and the antenna of each base station is used to determine the cooperation antenna set dynamically, therefore, the determined cooperation antenna set includes the antennae that have very strong interference to the mobile terminal, or the antennae that have been strongly interfered by the mobile station. By performing signal joint processing to the antennae, signal interference among adjacent cells can be reduced, better accuracy for detecting mobile terminal signals can be obtained, the accuracy for receiving signals by the mobile station is improved, and namely the communication quality between the mobile terminal and the base stations is improved.
