    摘要: A method, apparatus, and system for transmitting and controlling uplink diversity signals in a mobile communication device. While in a soft handoff situation, a mobile communications device may receive a phase feedback signal from a non-serving base station. The mobile device may calculate a modified phase parameter based on the phase feedback signal from the non-serving base station in order to minimize interference with the non-serving base station, for example, by calculating a modified value of a phase difference in a direction opposite to the direction desired by the non-serving base station. In some embodiments of the invention, the mobile device may determine whether to calculate the modified phase parameter in a direction opposite to the direction indicated by the phase feedback signal of the non-serving base station based on a comparison of power feedback signals received from the non-serving and serving base stations.
