A reverse power control method for a WLL is disclosed, in which the number of times of power control value transmission is reduced to 1. The disclosed method complements the related method, in which the power control of a radio interface unit is performed in units of 0.5 dB, so that power is controlled more concretely and flexibly. Unnecessary power consumption due to power control in the WLL system is thus reduced, and the load of the system is reduced, improving the reliability of the communication system.
