Abstract:
A method of controlling forward power of a mobile communication system, comprising the steps of:searching for an EI (erasure indicator) bit of reverse traffic channel frame by a control station, to determine if forward power control is required or not, the reverse traffic channel frame being transmitted from a mobile; controlling the forward power according to a transmission rate previously stored when the control station determines if a power control is required; and searching for the EI bit of reverse traffic channel frame after the controlling of forward power and varying the transmission rate according to information on a forward powers, wherein a variable rate run state and variable erasure run state of a full-rate run state are selectively transferred, to control the forward power, and the large power decreasing value BIG-DOWN when the EI bit of the reverse channel frame is continuously received as â€œ0â€ , and the power control value is raised with the large power increasing value BIG-UP after waiting of a predetermined period of frame when the EI bit is received as â€œ1â€ , and wherein in order to confirm the effect of an increase in the power control value, the control station determines if a power control is required after waiting of a predetermined period of time (FULL-WAIT)+1.
