ABSTRACT:
An outer loop power control apparatus and method in a mobile communication system are disclosed. If a first received frame has no errors and the raw BER of the first received frame is equal to or greater than a predetermined raw BER, a power control mode is changed to an adjustment mode. If a second received frame following the first received frame has no errors and the raw BER of the second received frame is less than the threshold raw BER in the adjustment mode, a target Eb/No is decreased by a product of a first step coefficient and a decrement unit. If the raw BER of the second received frame is equal to or greater than the threshold raw BER, the raw BERs of the first and second received frames are compared. If the raw BER of the second received frame is less than the raw BER of the first received frame, the target Eb/No is decreased by a product of a second step coefficient and the decrement unit.
