By the balance of communication link power, SNR balance guidelines and BER balance, under the base to meet the requirements of systems and not affecting thequality of call. Finally, the open-loop/closed-loop variable step length reverse power control is introduced, its principle is under the original open-loop power control to select suitable power control step by the new power control bit, and achieves a balanced system fastest and most effective.Keywords: Step, Power-control, Brethren interference, Proximity effect

依据通信链路的功率平衡准则、信噪比平衡准则和误码率平衡准则，在满足系统要求和不影响通话质量的基础上，最后提出了开环/闭环可变步长的反向功率控制，其原理是在原有的开环功率控制的基础上，依据新的功率控制比特，来选取合适的功率控制步长，以最快、最有效的方法使系统达到平衡。
