A power control device for a CDMA communication system using different kinds of spreading codes. In the power control device for a base station device, a first channel generator generates a first channel signal by spreading first input data with an orthogonal code and a second channel generator gene

A power control device for a CDMA communication system using different kinds of spreading codes. In the power control device for a base station device, a first channel generator generates a first channel signal by spreading first input data with an orthogonal code and a second channel generator generates a second channel signal by spreading second input data with a quasi-orthogonal code. The second channel signal has a gain higher than that of the first channel signal. A first gain controller controls power of the first channel signal and a second gain controller controls power of the second channel signal. An adder adds the first channel signal to the second channel signal, and a spreader spreads a signal output from the adder with a pseudo-random noise (PN) code. The base station transmits a response request message to a mobile station via the second channel, and retransmits the response request message after increasing a transmission power of the second channel when a response message is not received from the mobile station.
