For TD-SCDMA system,the closed-loop power control(PC)consists of inner-loop PC and outer-loop PC.The closed-loop PC algorithms in the system are elaborated,and a power control algorithm based on measurement statistics is produced.The closed-loop power control under some conditions such as different channel environment and different control parameters is simulated.It is found that the closed-loop PC can counteract the power loss of path loss and slow fading to a certain extent,so as to benefit the system performance.
