The technology that controls the uplink power in LTE system plays an important role in improving the user experience of cell users and network capacity,restraining inter-cell interference,as well as ensuring system performance.Aimming at the limitation of conventional uplink power control method in LTE system,a control algorithm of inner power with the minimum interference is proposed,thus ensuring the minimum singal-to-noise ratio required in communication quality, minimizing overall interference, effectively improving quality of network and system capacity,and promoting users’ experience.
