发明名称 Method and apparatus for distributed power control in cellular radio systems
摘要 The present invention discloses a method of and apparatus for regulating the power of signals transmitted by transmitting units, such as mobiles or base stations, that are using the same channel in a cellular radio system. An iterative process is disclosed in which the demands of synchrony and coordination among the transmitting units are relaxed. The power of the signals converges at a geometric rate to optimal transmission powers, where the optimal transmission powers are defined as the minimum powers required to maintain the ratio of carrier power to co-channel interference power at least as large as some pre-fixed target value obtained from quality of service considerations. As a result of relaxing the demands of synchrony and coordination, expensive clock or timing mechanisms are not required, thereby reducing the costs of power control. <IMAGE>
