The present invention relates to a method and apparatus of a forward traffic channel power control for a code division multiple access (CDMA) wireless local loop system not having a hand-off function. The present invention distinguishes between a normal mode and a threshold mode in a CDMA wireless local loop. Here, the total power is lower than a predetermined power threshold value in the normal mode, and the total power arrives at the predetermined power threshold value in the threshold mode. In addition, the present invention varies method of increasing/reducing the forward traffic channel power according to the determined mode. As a result, method and apparatus according to the present invention effectively reduces the forward link interference signal at nearby cells, and provides a proper traffic quality.
