Patent ID: 7218946

Claim:
An outer loop power control apparatus in a mobile communication system, comprising: a raw BER (Bit Error Rate) calculation unit for calculating a raw BER of a received frame; and a controller for: (a) if a raw BER of a present received frame is greater than or equal to a threshold raw BER, decreasing a target energy to noise ratio (Eb/No) by a product of a first step coefficient and a decrement unit, (b) if the raw BER of the present received frame is less than the threshold raw BER, determining if the raw BER of the present received frame is greater than or equal to a raw BER of a previous received frame, and (c) if the raw BER of the present received frame is less than the raw BER of the previous received frame, decreasing the target energy to noise ratio (Eb/No) by a product of a second step coefficient and the decrement unit.
